Cranial repair surgery is not considered a very large operation in the field of neurosurgical specialization and is a relatively common and routine operation in neurosurgery. The surgery is relatively safe and not very risky, and it is recommended that patients with cranial defects undergo cranial bone repair surgery as soon as possible. Cranial repair surgery is not really an overly complex procedure and requires several pre- and post-operative measures of time spent. First of all, before cranial bone repair surgery, preoperative examination is needed, including head CT, blood sampling, biochemistry, chest X-ray, relevant ultrasound and so on. Secondly, the operation time, if the operation goes well, it takes about 2 hours to complete, and the drainage tube can be removed and move off the ground on the second day after the operation. If the recovery is smooth, you can be discharged from the hospital on the seventh day after the operation. Basically, cranial repair surgery can be completed 4 days before surgery and about 7 to 8 days after surgery. In fact, the difficulty of cranial bone repair surgery is not very big, the important thing is the choice of material. the successful use of PEEK material, to make up for the various shortcomings of the traditional various materials, really strong and elastic, histocompatibility is also very good, the protective properties of the strong, but also resistant to high temperatures, is the ideal material to do cranial bone repair surgery. It is recommended that patients with cranial defects whose defect area is larger than three centimeters or more and who are aesthetically disturbed should go to regular hospitals as soon as possible to have their defects repaired and regain their health as soon as possible.
