Is skull repair surgery risky? Cranial repair surgery is not a very major surgery in the field of neurosurgery, and is a relatively common routine surgery in neurosurgery. The surgery is relatively safe and the risk of surgery is not high. Patients with skull defects are recommended to have skull repair surgery as soon as possible. Cranial repair is not really a too complicated surgery, and the time spent needs to be measured from several aspects before and after surgery. First of all, before the skull repair surgery, preoperative examination including head CT, blood sampling, biochemistry, chest X-ray, relevant ultrasound, etc. is required. Secondly, the operation time, if it goes well, will be completed in about 2 hours, and the drainage tube can be removed and the patient can move off the ground on the second day after the operation. If the recovery is smooth, the patient can be discharged from the hospital on the seventh day after surgery. Basically, skull repair surgery can be completed in 4 days before surgery and 7 to 8 days after surgery. The successful use of PEEK material has made up for the various defects of traditional materials and is really strong and elastic, histocompatible, protective, and resistant to high temperatures, making it the ideal material for skull repair surgery. Warm tip: It is recommended that patients with skull defects with a defect area greater than three centimeters or more, which is an obstacle to aesthetics, should go to a regular hospital for repair as soon as possible to recover their health as soon as possible.
