Craniotomy is a surgical procedure in which a portion of the skull is temporarily removed to allow access to the brain. This procedure is commonly performed to remove a brain tumor, alleviate pressure from a swollen brain, repair an aneurysm, or treat other brain conditions. During a craniotomy, the neurosurgeon carefully removes a portion of the skull, performs the necessary brain surgery, and then replaces the bone flap once the procedure is complete. The procedure requires precision and skill to ensure the safety and well-being of the patient. Studies in this area may focus on improving surgical techniques, reducing complications, and enhancing outcomes for patients undergoing craniotomy.
