Surgical Technique: An Overview
Meningiomas of different locations require varying surgical approaches that are primarily dictated by anatomic considerations inherent to each particular tumor location. Additional factors that lead to variations in surgical approach include the surgeon’s personal experience and preference.
The following basic principles hold for meningioma surgery of most locations:
- Optimal patient positioning and incision
- Craniotomy (skull opening), dural opening and the tumor exposure
- Early tumor devascularizaion (“cutting off the blood supply to the tumor”)
- Internal decompression and extracapsular dissection
- Early localization and preservation of adherent or adjacent neurovascular structures (the brain tissue, cranial nerves, blood vessels)
- Removal of the involved bone and dura
- Optimal dural reconstruction and operative wound closure
