Subtemporal approach for cavernous sinus meningiomas – Simple and effective

Surgical Neurology International, vol. 14, pp. 16

Abstract

Background: Over the past few decades, there has been a paradigm shift in treatment strategy for cavernous sinus meningiomas (CSMs). Preserving neurological function and cranial nerve (CN) decompression have become the primary goal of cases eligible for surgical treatment. Extensive skull base dissection and drilling can be avoided by approaching these lesions through a subtemporal route. Methods: We describe the subtemporal approach in a step-by-step fashion illustrating its advantages and pitfalls through and illustrative case. Results: The subtemporal approach to CSMs is a valuable alternative for CN decompression and maximal safe resection. We describe the technique in comparison to classical skull base approaches. Although rare, recurrence after adjuvant maximal radiation is possible leaving reoperation as the only treatment option. Conclusion: The subtemporal approach offers a less invasive alternative for initial and redo CN decompression and successful symptom control in patients suffering from CSM.
