What is performed to gain access to the brain or to relieve intracranial pressure.?

A procedure called a craniotomy is performed to gain access to the brain or relieve intracranial pressure. During a craniotomy, a section of the skull is temporarily removed to allow surgeons to operate on the brain, address issues such as tumors, bleeding, or swelling. This intervention can help alleviate pressure and facilitate treatment of various neurological conditions. After the procedure, the skull piece is usually replaced and secured.
