Overview

Meningiomas, with the exception of some tumors located at the skull base, can be successfully removed surgically, but the chances are less than 50%. In more difficult cases, stereotactic radiosurgery, such as Gamma Knife radiosurgery, remains a viable option.

Most pituitary adenomas can be removed surgically, often using a minimally invasive approach through the nasal cavity and skull base (trans-nasal, trans-sphenoidal approach). Large pituitary adenomas require a craniotomy (opening of the skull) for their removal. Radiotherapy, including stereotactic approaches, is reserved for the inoperable cases.

Techniques

Shunt Operation

A shunt operation is used not as a cure but to relieve the symptoms.[2] The hydrocephalus caused by the blocking drainage of the cerebrospinal fluid can be removed with this operation.
