Petroclival meningioma surgery

Some reviews on this topic have been conducted, but data remain fragmentary and based on retrospective case series, which hinders attempts at meta-analysis. Within this context, research into the use of minimally invasive approaches, including in neuroendoscopy, continues to emerge ¹⁾.

The surgical management of petroclival meningioma remains challenging, due to the difficulty of accessing the clivus region and the vital structures adjacent to the origin of these tumors.

The aiming is radical removal in small tumors for obtaining cure without morbidity ²⁾.

One of the most important and useful pieces of information in the preoperative evaluation of a large petroclival meningioma is the running course of the abducens nerve. The abducens nerve is small and has a long intracranial course, making it prone to compression by the tumor at various anatomical points. In relatively large tumors, it is difficult to confirm the entire course of the abducens nerve, even by heavy T2-thin slice imaging. Yang et al. report a case of successful preoperative estimation of the course of the abducens nerve that aided in its complete preservation during the resection of a large petroclival tumor ³⁾.
