The human skull is very hard and can resist most external impacts, but there are still some irresistible factors that can damage the skull, such as traffic accidents and brain surgery, which may cause skull defects. After skull defect, skull repair operation should be carried out in time, and it is generally appropriate to repair it about 3 months after injury.

Skull repair is a routine operation in neurosurgery, and its technology is relatively mature. Some patients ask that it usually takes several hours to repair the skull. This depends on the patient's physical function and the specific situation during the operation, because the operation involves scalp tissue, blood vessels, nerves and so on. This requires extra care. During the operation, there may be some situations that need the operator to deal with on the spot, such as reducing intracranial pressure and changing body position. Surgery usually takes about 2-4 hours.

It is also very important to choose better repair materials for skull repair surgery. At present, Professor Mu Cangshan's skull repair in Aviation General Hospital uses a very advanced PEEK material, also called PEEK material, and the clinical effect is very good. This material has good biocompatibility, complex formability, excellent mechanical properties, good protective performance and high postoperative comfort, and has gradually become the latest trend of skull repair materials.
