Abstract

Surgical access to the petroclival region poses a challenge to neurosurgeons. A wide range of approaches has been demonstrated in the past. In this video, the authors present a 69-year-old male patient who presented with 3-month history of worsening left-sided numbness. The tumor was totally removed in 2 sessions via anterior transpetrosal and retrosigmoid approaches, respectively. The authors demonstrate 2 separate skull base approaches to resect a petroclival meningioma and discuss pitfalls and problems of management for challenging meningiomas. The authors suggest that surgical approaches to petroclival meningiomas should be selected based on an individual case. A skull base team should be versatile in performing all these approaches.
