Cranial defects are not an uncommon disorder, and every year a large number of patients suffer from cranial defects for various reasons. Some of them are injured in car accidents, some of them are due to craniosynostosis with partial removal of skull flaps, some of them may be due to some lesion of their own skull and have to remove part of the skull, etc. The cranial defect, first of all, is somewhat frightening from the appearance, some will be severely collapsed, looking like a big pit on the head, and some will be bulging out, bulging out a big bag. Without the protection of the hard skull bone, the brain tissue will be easily damaged by the outside world directly, which will also seriously affect the brain nerve function. Therefore, skull repair should be performed in time. Some patients ask how long is the recovery period after skull repair. Patients do not need to worry about this issue, as cranial repair is a relatively routine surgery in neurosurgery, and the technology is very mature and the postoperative recovery is relatively fast. In particular, in recent years there has been an ideal material for cranial repair called polyether ether ketone, also known as PEEK, which is comparable to autologous cranial bone in all its properties and has a very good repair effect, and can recover better and faster after surgery. The use of PEEK, an advanced material, generally allows you to get out of bed two to three days after surgery if there are no special circumstances, and you can generally be discharged home a week after surgery to recuperate. After discharge from the hospital, pay attention to rest, do not strain, eat more nutritious food, ensure sufficient sleep, and recuperate for two to three weeks, and you will basically be fully recovered and can return to work. In this way, the recovery period after skull repair surgery is generally about one month. Of course, different patients may have individual differences, depending on the situation, and the main thing is to follow the guidance of the treating doctor.
