Abstract:
A series of 78 intracranial meningiomas (68 suprasellar, 10 intraventricular) were operated on in our Institute after the advent of the operating microscope. In our review, we discuss the microsurgical technical problems related to the preservation of vascular and brain structures in the removal of intraventricular and parasellar meningiomas. Basic diagnostic criteria to plan correctly the surgical approach will be emphasized. Mortality and morbidity in parasellar meningiomas is, in our opinion, related to the experience of the surgeon in using the operating microscope rather then in using the laser and CUSA. We will also discuss the utility of preoperative embolization of the lesion as well as the indications for intraoperative EC/IC bypass. Finally, morbidity and mortality related to different approaches for intraventricular meningiomas will be discussed.
Insights
Microsurgery for intracranial meningiomas, particularly suprasellar and intraventricular types, requires experienced surgeons for optimal outcomes. Surgeon experience with the operating microscope is key to minimizing risks in parasellar meningioma removal.
Area of Science:
- Neurosurgery
- Neurology
- Surgical Oncology
Background:
- Intracranial meningiomas are common primary tumors.
