Cranial repair is a relatively routine and very common surgical procedure to repair cranial defects caused by various reasons. The purpose is to reshape the skull, re-establish a closed cranial cavity, and maintain a stable intracranial environment to support intracranial life activities, so as not to cause various neurological injuries or even life-threatening injuries. Timing of repair: Regarding the timing of cranial repair, this has to be looked at separately. There are two main cases. One situation is open cranial damage, the wound is relatively clean, no intracranial hypertension, so that the repair surgery can be carried out in a period of time; the other situation is, closed craniocerebral trauma, due to intracranial hypertension and decompression of the bone flap surgery caused by cranial defects, now the view that also need to be early repair, generally in 2-3 months after the intracranial hypertension is relieved as soon as possible after the cranial bone repair. Postoperative recovery period: Skull repair surgery is a relatively routine surgery, does not involve the brain, will not cause any damage to the human body, the postoperative recovery room is very fast. Generally, you can get out of bed within two or three days after surgery, and you can be discharged from the hospital about one week to ten days after surgery. Of course, it also depends on the patient’s physical recovery, no special problems, usually not more than ten days. In addition, the clinical use of a new type of polyether ether ketone PEEK cranial bone repair material, causing excellent performance, can also make the postoperative recovery better and faster.
