After the operation, the piece of bone that was taken out is replaced and the muscle and skin are stitched together. A drain is placed inside the brain to allow the removal of excess blood left from the surgery. Recovery time depends upon the kind of brain surgery performed.

It is important for anyone suffering from acute or long lasting symptoms to contact their health professional. Symptoms left undiagnosed may lead to further complications if and when brain surgery is required.
