A craniotomy involves making an incision in the scalp and creating a hole known as a bone flap in the skull. The hole and incision are made near the area of the brain being treated. When the procedure is complete, the bone flap is secured in place with small plates. Very occasionally the bone is not replaced for specific reasons such as swelling. When left open, the procedure is known as a Craniectomy.
This procedure is used to remove a small amount of brain tissue or a tumour so it can be examined under a microscope. This involves a small incision and “pin” hole in the skull.
Minimally invasive neuroendoscopy
Neuroendoscopy uses endoscopes to remove brain tumors. The most common reason for this procedure is to remove Colloid cysts obstructing the flow of brain fluid in the ventricles of the brain and also to fenestrate membranes in the brain that may be interrupting fluid dynamics.
