Introduction

Meckel's Cave, a critical neuroanatomical structure located within the middle cranial fossa, is home to the trigeminal ganglion and is a region that surgeons frequently encounter during procedures aimed at addressing various pathologies such as trigeminal neuralgia, vestibular schwannomas, or petroclival meningiomas [1]. Due to the anatomical complexity and vital adjacent structures, choosing the most appropriate surgical approach to Meckel's Cave is a crucial decision that significantly impacts the safety and effectiveness of the procedure. Various surgical approaches have been proposed and refined over the years, each with its unique advantages and limitations. To inform this decision-making process, it is imperative to conduct a comprehensive quantitative anatomical analysis to compare these approaches. This paper seeks to explore the quantitative anatomical differences among surgical approaches to Meckel's Cave, offering insights into the potential implications for surgical outcomes, patient safety and the preservation of vital neurovascular structures [2].

Description

The anatomical complexity of Meckel's Cave presents a unique challenge to surgeons, as it houses the trigeminal ganglion and is surrounded by vital structures such as the internal carotid artery, the abducens nerve and the petrous apex. The surgical approaches to Meckel's Cave can be broadly categorized into the lateral subtemporal approach, the anterior petrosectomy approach, the retrosigmoid approach and the endoscopic endonasal approach. Each approach offers a distinct perspective and access to Meckel's Cave, aiming to maximize the extent of resection while minimizing complications and preserving neurological function. Quantitative anatomical analysis involves meticulous measurement and assessment of various parameters, including the angles, distances and dimensions of Meckel's Cave, its adjacent neurovascular structures and the corridors available to surgeons through each approach [3].

This analysis may reveal important differences in exposure, working angles and maneuverability that influence the choice of surgical approach. For example, the retrosigmoid approach may provide better visualization of the lower portions of Meckel's Cave but may require more cerebellar retraction, potentially increasing the risk of postoperative ataxia. The anterior petrosectomy approach may allow early access to the trigeminal nerve but may be associated with a higher risk of vascular injury. By conducting a quantitative anatomical analysis, it becomes possible to compare these approaches objectively, identifying their advantages and limitations and providing datadriven guidance for selecting the most appropriate approach on a case-bycase basis [4,5].

Conclusion

A quantitative anatomical analysis of surgical approaches to Meckel's Cave is a critical step in improving the precision and safety of procedures targeting this region. By quantifying the anatomical differences among approaches, clinicians gain a deeper understanding of the unique features, challenges and advantages associated with each technique. This knowledge can inform the surgical decision-making process, allowing for a more tailored and patientspecific approach. Furthermore, quantitative anatomical analysis facilitates the identification of potential risk factors and complications associated with each approach, thus enhancing surgical planning and patient safety. In conclusion, this quantitative anatomical analysis serves as a valuable resource for neurosurgeons, providing evidence-based insights into the nuances of Meckel's Cave anatomy and surgical access. The findings can guide surgeons in selecting the most appropriate approach, considering factors such as the pathology, patient characteristics and the desired extent of resection. This approach offers a promising avenue for optimizing surgical outcomes, minimizing complications and enhancing the overall quality of patient care in procedures related to Meckel's Cave pathologies.
