Craniotomy Surgery

A craniotomy is a procedure in which a segment of the skull bone is removed to access the brain. After the surgery, this segment is replaced with either a bone graft or a bone flap.

This surgery is performed to remove aneurysms and brain tumours or to excise brain tumours surgically. In addition, in cases of trauma or injury, there are chances of swelling developing intracranially; to prevent that, a craniotomy may be performed. The surgery is performed by an experienced neurosurgeon.

In some cases, the patient is kept awake to monitor brain function, while in others, they are sedated. For instance, if the surgery is to be performed in areas of the brain that controls movement, vision or speech, patients are kept awake to monitor brain function. This ensures that the surgeon is treating the right area of the brain. In addition, it lowers the risk of developing speech, movement or vision impairment.
