The time to perform cranial repair for cerebral hemorrhage craniotomy is usually about 3 months after surgery. The most common type of craniotomy for cerebral hemorrhage that requires repair is debridement. Cerebral edema occurs after cerebral hemorrhage surgery. If the cerebral edema is not relieved by aggressive medications or other treatments, or if the intracranial pressure continues to increase, it is important to consider prompt debridement to prevent compression of the brain tissues and herniation of the brain. Some patients undergoing decompression surgery may experience headache, dizziness, memory problems, mood changes, emotional disturbances, and contralateral motor incoordination in the weeks to months after the surgery, which is called “post-decompression syndrome”. Cranial repair (early repair) is usually performed at 3 months after surgery if there are no specific changes in the condition after the flap decompression surgery. Early cranial repair is more conducive to the recovery of the patient’s condition. Cranial repair can normalize the blood circulation in the cranium and restore the normal intracranial pressure.
