Showing Brain Tumor Surgery

Traveling From India

Although there is no generally accepted therapeutic management for primary brain tumors (or brain tumours), a surgical attempt at tumor (tumour) removal or at least cytoreduction (that is, removal of as much tumor as possible, in order to reduce the number of tumor cells available for proliferation) is considered in most cases. Many meningiomas, with the exception of some tumors located at the skull base, can be successfully removed surgically. 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). In more difficult cases, stereotactic radiosurgery, such as gamma knife radiosurgery, remains a viable option. Large pituitary adenomas require a craniotomy (opening of the skull) for their removal. Radiotherapy, including stereotactic approaches, is reserved for the inoperable cases.
