Scenario Analysis: This scenario is professionally challenging because it requires balancing the imperative for continuous quality improvement and the advancement of neurosurgical oncology with the ethical and regulatory obligations surrounding patient data, research integrity, and the translation of findings into clinical practice. The pressure to innovate and improve outcomes must be tempered by rigorous adherence to established protocols and ethical guidelines to ensure patient safety and maintain public trust. Correct Approach Analysis: The best professional practice involves a systematic, multi-faceted approach that integrates simulation, quality improvement initiatives, and research translation under a robust ethical and regulatory framework. This includes establishing clear protocols for simulation-based training, ensuring its fidelity and relevance to clinical scenarios. Quality improvement efforts should be data-driven, utilizing anonymized patient outcomes and process metrics to identify areas for enhancement, with findings rigorously documented and shared. Research translation requires a structured pathway from discovery to implementation, involving peer review, ethical board approval for any research involving patient data or interventions, and careful evaluation of evidence before widespread adoption. This approach prioritizes patient well-being, data privacy, and the scientific validity of advancements, aligning with the principles of responsible innovation and evidence-based medicine. Incorrect Approaches Analysis: One incorrect approach involves prioritizing the immediate implementation of novel techniques based on anecdotal evidence or preliminary simulation results without rigorous validation or ethical review. This bypasses essential quality control mechanisms and can expose patients to unproven or potentially harmful interventions, violating the principle of “do no harm” and failing to adhere to research ethics guidelines that mandate thorough evaluation before clinical application. Another unacceptable approach is to conduct quality improvement initiatives or research in silos, without transparent data sharing or integration into broader learning systems. This limits the potential for widespread benefit, hinders collaborative advancement, and may lead to duplicated efforts or the perpetuation of suboptimal practices. It also fails to meet expectations for a culture of continuous learning and improvement within the specialty. A further flawed approach is to rely solely on simulation without a clear strategy for translating those simulated skills and insights into tangible improvements in patient care. Simulation is a tool, not an end in itself. Without a defined pathway for quality improvement and research translation, the investment in simulation may not yield its full potential for enhancing patient outcomes, representing a missed opportunity for advancing the field. Professional Reasoning: Professionals should adopt a framework that emphasizes a cyclical process of learning, improvement, and innovation. This begins with identifying areas for improvement through data analysis and patient feedback. Simulation can then be used to develop and refine new techniques or protocols. Rigorous, ethically approved research is essential to validate these advancements. Finally, a structured process for translating validated research findings into clinical practice, coupled with ongoing quality monitoring, ensures that patient care consistently benefits from the latest evidence-based advancements. Transparency, ethical oversight, and a commitment to patient safety must underpin every step.

Scenario Analysis: This scenario is professionally challenging because it requires balancing the need for rigorous assessment and competency assurance with fairness and support for candidates undergoing a high-stakes examination. Misinterpreting or misapplying retake policies can lead to undue stress, perceived unfairness, and potentially compromise the integrity of the assessment process. Careful judgment is required to ensure policies are applied consistently and ethically, while also considering individual circumstances where appropriate and within policy. Correct Approach Analysis: The best professional practice involves a thorough understanding and consistent application of the established blueprint weighting, scoring, and retake policies as outlined by the Pan-Asia Neurosurgical Oncology Competency Assessment framework. This approach prioritizes transparency, fairness, and the maintenance of high standards for neurosurgical oncology practice. Adherence to these documented policies ensures that all candidates are assessed against the same criteria, and that retake decisions are based on objective performance metrics and predefined conditions, thereby upholding the credibility of the assessment. Incorrect Approaches Analysis: One incorrect approach involves making subjective exceptions to retake policies based on perceived effort or personal circumstances not explicitly covered by the assessment framework. This undermines the principle of equal treatment for all candidates and can introduce bias, potentially leading to a perception of unfairness and compromising the standardized nature of the competency assessment. It deviates from the objective criteria established for ensuring competence. Another incorrect approach is to interpret the blueprint weighting and scoring in a manner that allows for arbitrary adjustments to a candidate’s score to influence retake eligibility. This bypasses the established scoring mechanisms and compromises the integrity of the assessment’s design, which is intended to objectively measure specific competencies. Such actions can lead to unqualified individuals being deemed competent or qualified individuals being unfairly penalized. A further incorrect approach is to apply retake policies inconsistently across different candidates, perhaps due to personal relationships or external pressures. This is a direct ethical failure, violating principles of fairness, impartiality, and professional integrity. Inconsistent application erodes trust in the assessment process and can have serious implications for patient safety if competence is not accurately determined. Professional Reasoning: Professionals involved in competency assessments should adopt a decision-making framework that prioritizes adherence to established policies and guidelines. This involves: 1) Clearly understanding the assessment blueprint, scoring rubrics, and retake policies. 2) Applying these policies consistently and objectively to all candidates. 3) Documenting all assessment decisions and the rationale behind them. 4) Seeking clarification from assessment authorities when faced with ambiguous situations. 5) Recognizing the ethical imperative to uphold the integrity and fairness of the assessment process, which ultimately serves to protect patient welfare.

Scenario Analysis: This scenario is professionally challenging because it requires balancing the immediate need for surgical intervention with the ethical imperative of informed consent, especially when dealing with a vulnerable patient population and potential communication barriers. The neurosurgeon must navigate complex family dynamics and ensure the patient’s autonomy is respected, even if the patient’s capacity to consent is compromised. Careful judgment is required to avoid coercion while ensuring the patient receives appropriate care. Correct Approach Analysis: The best approach involves a multi-faceted strategy that prioritizes obtaining informed consent directly from the patient to the greatest extent possible, while also engaging the family as surrogate decision-makers when the patient’s capacity is diminished. This includes a thorough explanation of the diagnosis, prognosis, treatment options (including risks, benefits, and alternatives), and the opportunity for the patient to ask questions. If the patient lacks capacity, the neurosurgeon should seek consent from the legally authorized surrogate decision-maker, ensuring they understand their role and the patient’s previously expressed wishes or best interests. This aligns with fundamental ethical principles of patient autonomy and beneficence, and is supported by general medical guidelines emphasizing patient-centered care and shared decision-making. Incorrect Approaches Analysis: One incorrect approach is to proceed with surgery solely based on the family’s consent without making a diligent effort to assess the patient’s capacity or involve them in the decision-making process to the extent possible. This fails to uphold the principle of patient autonomy and could lead to treatment that is not aligned with the patient’s own values or wishes. Another incorrect approach is to delay surgery indefinitely due to minor communication barriers or the family’s initial reluctance, without adequately exploring ways to overcome these obstacles or reassessing the urgency of the situation. This could compromise patient safety and well-being by delaying necessary treatment, potentially violating the principle of beneficence. A further incorrect approach is to pressure the family into consenting to the surgery by emphasizing the dire consequences of inaction without fully exploring all available palliative or less invasive options, or without ensuring the family feels adequately informed and supported in their decision-making. This can be perceived as coercive and undermines the ethical foundation of informed consent. Professional Reasoning: Professionals should employ a structured decision-making process that begins with a comprehensive assessment of the patient’s medical condition and capacity to consent. This should be followed by open and honest communication with the patient and their family, providing clear and understandable information about all treatment options. When capacity is questionable, a formal assessment should be conducted. The process should involve shared decision-making, respecting the patient’s values and preferences, and ensuring that any surrogate decision-maker is acting in the patient’s best interest. Documentation of all discussions and decisions is crucial.

Scenario Analysis: This scenario is professionally challenging because it requires a nuanced understanding of the purpose and eligibility criteria for a specialized competency assessment. Misinterpreting these requirements can lead to wasted resources, missed opportunities for professional development, and potentially undermine the integrity of the assessment process itself. Careful judgment is required to align individual aspirations and qualifications with the stated objectives of the Critical Pan-Asia Neurosurgical Oncology Competency Assessment. Correct Approach Analysis: The best approach involves a thorough review of the official documentation outlining the purpose and eligibility for the Critical Pan-Asia Neurosurgical Oncology Competency Assessment. This documentation, typically provided by the organizing body, will clearly define the target audience, the specific skills and knowledge the assessment aims to evaluate, and the prerequisite qualifications or experience necessary for candidates. Adhering to these published guidelines ensures that individuals are applying for an assessment that aligns with their professional goals and that they meet the established standards for participation. This upholds the principle of fairness and ensures that the assessment serves its intended purpose of identifying and validating high-level competency in Pan-Asian neurosurgical oncology. Incorrect Approaches Analysis: Relying solely on anecdotal evidence or informal discussions with colleagues about the assessment’s purpose and eligibility is professionally unacceptable. This approach risks misinterpreting the assessment’s objectives and can lead to individuals applying who do not meet the actual requirements, or conversely, qualified individuals being deterred from applying due to misinformation. This failure to consult official sources undermines the transparency and validity of the assessment process. Assuming that any neurosurgeon with an interest in oncology is automatically eligible, without verifying specific criteria, is also professionally unsound. The Critical Pan-Asia Neurosurgical Oncology Competency Assessment is likely designed for a specific level of expertise and experience within the subspecialty, not for general interest. This broad assumption disregards the specialized nature of the assessment and the need for demonstrated proficiency. Focusing exclusively on the perceived prestige or career advancement opportunities associated with the assessment, without first confirming eligibility and purpose, represents a misaligned professional motivation. While career advancement is a valid outcome, it should not supersede the fundamental requirement of meeting the assessment’s stated purpose and eligibility criteria. This approach prioritizes personal gain over adherence to established professional standards. Professional Reasoning: Professionals should approach such assessments by prioritizing official information. This involves actively seeking out and meticulously reviewing the assessment’s charter, guidelines, and eligibility requirements published by the governing body. If any ambiguities exist, direct communication with the assessment administrators is the most appropriate next step. This systematic and evidence-based approach ensures that decisions regarding participation are informed, ethical, and aligned with the assessment’s intended outcomes.

Scenario Analysis: This scenario is professionally challenging because it requires balancing the immediate need for patient care with the ethical and regulatory obligations surrounding informed consent, particularly when dealing with complex and potentially life-altering neurosurgical oncology procedures. The pressure to act quickly in a critical situation can sometimes lead to shortcuts that compromise patient autonomy and legal compliance. Careful judgment is required to ensure that all necessary steps are taken to obtain valid consent, even under duress. Correct Approach Analysis: The best professional practice involves a structured approach to obtaining informed consent that prioritizes clear communication and patient understanding. This includes ensuring the patient (or their legally authorized representative) fully comprehends the nature of the proposed surgery, its risks, benefits, and alternatives, and has the capacity to make a decision. Documentation of this process, including the patient’s understanding and voluntary agreement, is paramount. This aligns with the fundamental ethical principle of patient autonomy and the regulatory requirement for documented informed consent before medical procedures. Incorrect Approaches Analysis: One incorrect approach involves proceeding with surgery based on a verbal agreement from a family member without a formal assessment of the patient’s capacity or a documented consent process. This fails to uphold patient autonomy if the patient is capable of consenting and bypasses the legal requirement for documented informed consent, potentially exposing the medical team and institution to legal repercussions. Another incorrect approach is to delay necessary surgery significantly to obtain exhaustive, non-urgent consent discussions, potentially jeopardizing the patient’s outcome. While thoroughness is important, it must be balanced with the urgency of the clinical situation. The failure here lies in not adapting the consent process to the emergent nature of the condition while still ensuring core elements of consent are met. A third incorrect approach is to rely solely on a pre-existing general consent form signed at admission, without specific discussion of the neurosurgical oncology procedure. General consent forms typically do not cover the specific risks, benefits, and alternatives of complex surgical interventions, rendering the consent for this particular procedure invalid and ethically insufficient. Professional Reasoning: Professionals should employ a tiered approach to informed consent. In emergent situations, the focus shifts to obtaining consent as quickly as possible while still ensuring the patient or their representative understands the critical information. This involves a clear, concise explanation of the immediate necessity, the proposed intervention, and the most significant risks and benefits. If the patient lacks capacity, the process must involve the legally authorized representative, with a clear understanding of their role. Documentation should reflect the circumstances and the information provided. The decision-making framework should prioritize patient well-being, respect for autonomy, and adherence to legal and ethical standards, adapting the process to the clinical context without compromising its core integrity.

This scenario presents a professional challenge due to the inherent risks associated with neurosurgical oncology procedures, specifically the use of energy devices. Ensuring patient safety and optimal surgical outcomes requires meticulous attention to operative principles, appropriate instrumentation selection, and strict adherence to energy device safety protocols. The complexity arises from the need to balance effective tumor resection with the preservation of critical neural structures, where even minor deviations can have significant consequences. Careful judgment is required to anticipate potential complications and implement preventative measures. The best professional practice involves a comprehensive pre-operative assessment and planning phase that includes a thorough review of the patient’s imaging, a detailed surgical strategy, and a specific plan for energy device utilization. This includes confirming the availability of appropriate devices, ensuring all safety checks are completed, and that the surgical team is familiar with the specific device settings and potential risks. During the procedure, continuous monitoring of energy device application, including visual confirmation of tissue interaction and appropriate power settings, is paramount. Post-operatively, a review of the procedure, including any intra-operative events related to energy device use, contributes to continuous learning and improvement. This approach aligns with the ethical principles of beneficence and non-maleficence, prioritizing patient well-being and minimizing harm. It also implicitly adheres to best practice guidelines for surgical safety, which emphasize thorough preparation and intra-operative vigilance. An approach that prioritizes immediate intra-operative decision-making based on perceived tissue response without a pre-established energy device protocol is professionally unacceptable. This failure to plan can lead to suboptimal energy application, potentially causing unintended thermal injury to adjacent healthy tissue or inadequate tumor ablation. Such an approach neglects the fundamental principle of risk mitigation through proactive planning and may violate guidelines that mandate a structured approach to surgical technology use. Another professionally unacceptable approach is to delegate the responsibility for energy device safety checks and settings solely to junior members of the surgical team without direct senior oversight or verification. While teamwork is essential, ultimate responsibility for patient safety rests with the senior surgeon. This delegation without adequate supervision can lead to errors in device selection, calibration, or application, increasing the risk of adverse events. This deviates from established principles of surgical leadership and accountability. Finally, an approach that focuses solely on the technical aspects of tumor removal while neglecting the specific safety considerations of the energy device being used is also unacceptable. This narrow focus overlooks the potential for device-related complications, such as charring, char block formation, or unintended collateral thermal damage, which can significantly impact patient outcomes and recovery. Adherence to operative principles must encompass the safe and effective use of all surgical tools, including energy devices. The professional decision-making process for similar situations should involve a systematic, multi-faceted approach. This begins with a robust pre-operative planning phase that includes a detailed review of the surgical site, patient anatomy, and the specific requirements for energy device use. It necessitates a clear understanding of the available instrumentation and energy modalities, along with their associated risks and benefits. Intra-operatively, constant vigilance, clear communication within the surgical team, and a willingness to adapt based on real-time feedback are crucial. Post-operative debriefing and analysis of surgical events, particularly those involving instrumentation or energy devices, are vital for continuous quality improvement and the refinement of surgical techniques and safety protocols.

Scenario Analysis: The scenario presents a neurosurgical oncology candidate preparing for a critical Pan-Asia assessment. The challenge lies in balancing comprehensive preparation with efficient time management, especially given the vastness of the subject matter and the high stakes of the competency assessment. A candidate must navigate a complex landscape of resources, potentially leading to information overload or the neglect of crucial areas. Effective preparation requires strategic planning, not just exhaustive study. Correct Approach Analysis: The best approach involves a structured, multi-modal preparation strategy that prioritizes foundational knowledge, integrates practical application, and incorporates regular self-assessment. This begins with a thorough review of core neurosurgical oncology principles, followed by targeted study of specific tumor types, treatment modalities, and recent advancements relevant to the Pan-Asia context. Incorporating case-based learning, simulation exercises (where applicable), and engaging with peer-reviewed literature are vital. Crucially, this approach includes a realistic timeline with dedicated periods for review and practice examinations, allowing for identification and remediation of knowledge gaps. This aligns with best practices in professional development and competency assessment, emphasizing a holistic and evidence-based approach to learning and skill acquisition. The regulatory and ethical imperative is to ensure the candidate possesses the necessary knowledge and skills to provide safe and effective patient care, which this structured preparation directly supports. Incorrect Approaches Analysis: One incorrect approach is to solely rely on memorizing vast amounts of information from a wide array of sources without a structured plan or focus on application. This can lead to superficial understanding and an inability to synthesize knowledge under pressure, failing to meet the competency assessment’s goal of evaluating practical application of knowledge. It also risks inefficient use of preparation time, potentially leaving critical areas unaddressed. Another incorrect approach is to focus exclusively on theoretical knowledge without engaging in practical application or simulated scenarios. Competency assessments, particularly in surgical fields, evaluate not just what a candidate knows, but how they apply that knowledge in clinical decision-making and procedural contexts. Neglecting this practical dimension means the candidate may not be adequately prepared for the applied nature of the assessment. A third incorrect approach is to defer preparation until immediately before the assessment, relying on last-minute cramming. This method is demonstrably ineffective for complex subjects requiring deep understanding and retention. It increases the risk of burnout, anxiety, and superficial learning, making it highly probable that critical knowledge and skills will be overlooked or poorly retained, thereby failing to meet the standards of a rigorous competency assessment. Professional Reasoning: Professionals preparing for high-stakes competency assessments should adopt a strategic, phased approach. This involves first understanding the assessment’s scope and format, then identifying key knowledge and skill domains. A realistic timeline should be established, allocating time for foundational learning, in-depth study of specific areas, practical application, and regular self-evaluation. Seeking guidance from mentors or experienced colleagues can provide valuable insights into effective preparation strategies. Continuous self-assessment and adaptation of the study plan based on identified weaknesses are crucial for success and for upholding professional standards of competence.

The risk matrix shows a moderate likelihood of a significant complication during a complex glioblastoma resection in a patient with a history of prior radiation therapy. This scenario is professionally challenging due to the inherent risks associated with re-operating on irradiated tissue, the potential for neurological deficit, and the need to balance aggressive tumor removal with patient safety and quality of life. Careful judgment is required to select the optimal surgical strategy. The best professional practice involves a meticulous, stepwise approach to tumor debulking, prioritizing the preservation of critical neurological function. This includes utilizing advanced intraoperative imaging techniques such as intraoperative MRI or ultrasound to maximize tumor resection while minimizing damage to surrounding healthy brain tissue. Furthermore, employing intraoperative neuromonitoring, including motor evoked potentials and somatosensory evoked potentials, is crucial for real-time assessment of neural pathway integrity. This approach is correct because it directly aligns with the ethical principles of beneficence (acting in the patient’s best interest) and non-maleficence (avoiding harm). It also adheres to best practice guidelines for neurosurgical oncology, which emphasize maximizing oncological outcomes while safeguarding neurological function. An approach that involves aggressive, rapid resection without continuous neuromonitoring or advanced intraoperative imaging is professionally unacceptable. This would represent a failure to employ available technologies that mitigate risk and could lead to significant, avoidable neurological injury, violating the principle of non-maleficence. Another professionally unacceptable approach would be to defer to the patient’s family’s initial, potentially emotional, request for maximal resection at all costs, without a thorough discussion of the risks and benefits of different surgical strategies and the potential for irreversible neurological deficits. This fails to uphold the principle of patient autonomy by not ensuring fully informed consent based on a comprehensive understanding of the surgical implications. It also neglects the surgeon’s professional responsibility to guide treatment decisions based on medical expertise and ethical considerations. A further professionally unacceptable approach would be to limit the resection significantly due to the perceived risks of irradiated tissue, without adequately exploring all available techniques to safely maximize tumor removal. This could lead to suboptimal oncological control, potentially impacting long-term survival and quality of life, and may not fully align with the principle of beneficence if a more aggressive, yet safe, resection was feasible with appropriate techniques. Professionals should employ a structured decision-making process that begins with a thorough assessment of the patient’s condition and the tumor characteristics. This should be followed by a comprehensive discussion with the patient and their family about the risks, benefits, and alternatives to surgery, including the potential for different surgical approaches and their associated outcomes. The surgeon should then formulate a surgical plan that incorporates the latest evidence-based techniques and technologies to optimize both oncological efficacy and patient safety, continuously reassessing the plan intraoperatively based on real-time feedback.

This scenario is professionally challenging due to the rapid deterioration of a patient with severe head trauma, requiring immediate and decisive action under immense pressure. The need to balance aggressive resuscitation with the potential for iatrogenic harm, coupled with the ethical imperative to act in the patient’s best interest, demands a systematic and evidence-based approach. Careful judgment is required to prioritize interventions and adapt the resuscitation strategy based on evolving clinical data. The best professional practice involves a structured, protocol-driven approach to resuscitation, prioritizing the ABCDE (Airway, Breathing, Circulation, Disability, Exposure) assessment and management. This includes securing the airway, ensuring adequate oxygenation and ventilation, managing circulatory status to maintain adequate cerebral perfusion pressure, and performing a rapid neurological assessment. This approach aligns with established neurotrauma guidelines and best practices, emphasizing early identification and management of life-threatening conditions to prevent secondary brain injury. The ethical justification lies in the principle of beneficence, acting to benefit the patient by mitigating further harm and optimizing the chances of recovery, and non-maleficence, avoiding actions that could worsen the patient’s condition. Adherence to established protocols ensures a consistent and evidence-based standard of care. An incorrect approach would be to focus solely on one aspect of resuscitation, such as aggressive fluid resuscitation without considering intracranial pressure (ICP) management. This could lead to fluid overload and exacerbate cerebral edema, worsening neurological outcomes. Another incorrect approach would be to delay definitive airway management, leading to hypoxia and hypercapnia, both of which are detrimental to the injured brain. Furthermore, administering medications without a clear indication or understanding of their potential impact on ICP or cerebral perfusion pressure would be professionally unacceptable, violating the principle of non-maleficence. Professionals should employ a systematic decision-making process that begins with a rapid primary survey (ABCDE), followed by a secondary survey and ongoing reassessment. This process should be guided by established institutional protocols and evidence-based guidelines for neurotrauma. Critical thinking involves interpreting clinical signs, understanding the pathophysiology of brain injury, and anticipating potential complications. Continuous monitoring and a willingness to adapt the resuscitation strategy based on the patient’s response are paramount.

The risk matrix shows a patient presenting with a newly diagnosed glioblastoma multiforme (GBM) requiring surgical resection. This scenario is professionally challenging due to the inherent complexity of neurosurgical oncology, the aggressive nature of GBM, and the critical need for precise surgical intervention while minimizing neurological deficits. Balancing oncological goals with patient safety and functional preservation demands meticulous planning and execution, informed by a deep understanding of applied surgical anatomy, physiology, and perioperative sciences. Careful judgment is required to navigate potential intraoperative complications and optimize postoperative recovery. The best professional approach involves a comprehensive preoperative assessment that includes detailed neuroimaging review to delineate tumor extent, proximity to eloquent areas, and vascular supply. This is followed by meticulous surgical planning, considering the optimal trajectory, potential for maximal safe resection, and anticipation of anatomical variations. Intraoperatively, the surgeon must employ advanced techniques such as intraoperative neurophysiological monitoring and intraoperative imaging to guide resection and preserve critical neural pathways. Postoperatively, a structured management plan focusing on neurological assessment, pain control, and early mobilization is essential. This approach is correct because it aligns with the principles of patient-centered care, evidence-based practice, and the ethical obligation to provide the highest standard of care in neurosurgery. It prioritizes minimizing harm and maximizing functional outcomes, which are paramount in the management of malignant brain tumors. Adherence to established neurosurgical protocols and continuous professional development in surgical techniques and perioperative management are implicitly required. An incorrect approach would be to proceed with surgery based solely on gross anatomical landmarks without detailed preoperative imaging review and advanced intraoperative guidance. This fails to account for individual anatomical variations and the potential for subtle tumor infiltration into critical brain regions, increasing the risk of significant neurological injury and incomplete resection. Ethically, this demonstrates a lack of due diligence and a disregard for patient safety. Another incorrect approach would be to prioritize aggressive tumor debulking at the expense of significant neurological deficits, without adequately discussing the risks and benefits with the patient or their family. This violates the principle of beneficence and non-maleficence, as well as the ethical requirement for informed consent. The potential for long-term disability outweighs the oncological benefit if it leads to a severely impaired quality of life. A further incorrect approach would be to neglect comprehensive perioperative care, such as inadequate pain management or delayed mobilization, leading to preventable complications like deep vein thrombosis or pneumonia. This demonstrates a failure to uphold the duty of care throughout the entire patient journey, from preoperative planning to postoperative recovery, and can significantly impact the patient’s overall outcome and recovery trajectory. Professionals should employ a decision-making framework that begins with a thorough understanding of the patient’s condition and the relevant anatomy. This involves integrating all available diagnostic information, considering the patient’s overall health status and preferences, and engaging in collaborative decision-making with the patient and their family. The framework should emphasize risk assessment, meticulous planning, the judicious use of technology and monitoring, and a commitment to comprehensive perioperative care, all guided by ethical principles and current best practices in neurosurgical oncology.
