Craniotomy is an operative technique used for meningiomas and brain tumors.

The operation is usually performed under general anesthesia, but in some cases it can be more suitable to keep the patient awake during the procedure.

The skull is opened by excising a free bone flap with a saw. After that, the dura is opened. The subsequent surgical procedure depends on the tumor type and location.

It is often problematic to achieve a satisfactory resection of the tumor and decompression of the surrounding brain tissue if the tumor invades areas with a high degree of functionality. A radical resection if frequently not possible for glioblstoma multiforme.

In the event of growth of remaining tumor tissue or local recurrence, a re-operation should be evaluated depending on the tumor type.
