Cranial Repair Surgery is a short procedure with a short recovery period. The recovery period is also related to the material used to repair the skull, which is described in detail next. The skull is a very important organ in the human body, it plays an important role in protecting the brain tissue, maintaining normal intracranial pressure, etc. However, there are still some people in life who have skull defects for various reasons. In fact, in today’s advanced medical environment, cranial bone repair has been a relatively routine operation in neurosurgery, the operation is not complex, not very difficult, can be said to be not a very big operation. However, the material used for cranial bone repair is very important. Although the titanium mesh material widely used in clinical practice is much more advanced than other traditional materials, there are still many problems and complications, which affect the repair effect and limit the quality of life of the patients in the future. Cranial repair surgery is a relatively routine procedure in neurosurgery. It is a relatively short procedure with a short recovery period. From the time of diagnosis, to the surgery, to the time of discharge, the whole process is 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. Post-operative problems such as chronic pain, high subcutaneous fluid accumulation, sensitivity to hot and cold reactions, chronic cutting ulcers, etc. may occur, and it also affects post-operative medical examinations such as MRI and CT. We use peek material for cranial bone repair, the clinical effect and skull perfection are very good. peek is currently internationally recognized as a good material for perfection and cranial bone repair standard. Patients with cranial defects should go to regular hospitals as soon as possible to take appropriate repair materials for cranial bone repair, early repair and early recovery of health.
