The skull is a very important organ in the human body, it plays an important role in protecting brain tissue and maintaining normal intracranial pressure, however, there are still some people who suffer from skull defects for various reasons. However, there are still some people who have skull defects for various reasons. This requires skull repair surgery. In fact, in today’s developed medical environment, cranial repair is already a relatively routine surgery in neurosurgery, which is not complicated and not very difficult, so it is not a big surgery. However, the material used for skull repair is very important. The whole procedure of skull repair is short and the postoperative recovery period is not long. From admission to diagnosis, to surgery, to discharge from the hospital, the whole process takes about half a month or so. This recovery, of course, is also related to the materials used for skull repair. For example, the titanium mesh material, which is widely used in clinical practice, has some problems. Postoperative problems such as chronic pain, more subcutaneous fluid, sensitivity to hot and cold reactions, chronic cutting ulcers, etc. may occur, and they also affect postoperative medical examinations such as MRI and CT. Currently, we use the new polyetheretherketone PEEK material for cranial repair, with excellent clinical results and skull perfection.PEEK is also a good material for the current internationally recognized standard of perfect kimono cranial repair. One, the main components of PEEK are hyaluronic acid and Ebenezer, which are highly biocompatible and cause postoperative complications and foreign body reactions, which are basically absent in clinical practice. Two, PEEK has a better modulus of elasticity, and bone plates made with 3D printing technology can be perfectly shaped in three dimensions before surgery based on patient monitoring data, perfectly restoring the original structure of the skull. Third, the strength, insulation, and stability of PEEK are similar to that of autologous cranial bone, and will not interfere with future medical examinations such as CT MRI, or even if craniotomy is required later, this material can be reused after sterilization. The skull repair surgery treatment must be carried out in a regular hospital without delay, and early treatment can lead to early recovery.
