Cranial Repair Surgery This procedure is a short procedure as a whole and the recovery period after surgery is not long. Recovery is also related to the material used to repair the skull. The skull is a very important organ in the human body, it plays an important role in protecting the brain tissue and maintaining normal intracranial pressure, however, there are still some people who suffer from skull defects for various reasons. This requires cranial repair surgery. Cranial repair surgery is a routine neurosurgical procedure. The procedure is short and the recovery period is not long. From the time of admission to the hospital, to the surgery, to the time of 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 cranial repair. For example, the titanium mesh material, which is widely used in clinical practice today, has some problems. Problems such as chronic pain, high subcutaneous fluid accumulation, sensitivity to hot and cold reactions, chronic cutting ulcers, etc. may occur after the operation, and it also affects postoperative medical examinations such as MRI and CT. We use PEEK material for cranial bone repair surgery, the clinical effect and skull perfection are very good.PEEK is also the current international recognition of the perfect and good material for cranial bone repair standard. First, the main components of PEEK are hyaluronic acid and Ebève, which are highly biocompatible, and the phenomenon of postoperative complications and foreign body reaction is basically absent in the clinic. Secondly, PEEK has a better modulus of elasticity, and the bone plate made by 3D technology printing can be perfectly three-dimensionally shaped according to the patient’s monitoring data before the operation, which perfectly restores the original structure of the skull. Third, the strength, insulation, stability of PEEK is similar to the autologous skull, and will not affect the future to do CT MRI and other medical examinations, and even in the future, if the need for craniotomy surgery, this material can be reused after sterilization and disinfection.
