Craniotomy is the most common technique used to remove the brain tumor. It is a surgical procedure to temporarily remove of a part of the bone from the skull, for better access to the intracranial area of the brain. Depending on the location of the tumor and accessibility, it either completely or partially removed. If tumor is partially removed, then chemotherapy or radiotherapy are also required for treatment.
The temporarily removed portion of the skull, called bone flap, is replaced to its original position and fastened to its place with screws and plates.
Depending on which portion of the skull is removed and replaced on, the procedure is categorized into Frontal, Pterional or Junctional Crainotomy.
A craniotomy that involves the use of a camera with a lighted scope inserted through a small incision in the skull is called an endoscopic craniotomy. When imaging and computer assisted navigation system are used in a craniotomy procedure, it is called stereotactic craniotomy.
