There are some people who have skull damage due to craniosynostosis or traumatic brain injury, and if they do not have skull repair in time, they will face more danger. Because the skull is a protective shield for the brain, when the skull is defective, the intracranial tissues lack protection and will be exposed to external aggressions and dangers. The reason for cranial repair surgery is to restore the closure of the cranial cavity and to keep the intracranial pressure stable, thus reducing the occurrence of cranial defect syndrome. Moreover, in neurosurgery, cranial repair surgery is still relatively classic and safe, so patients do not need to worry. At present, many local hospitals may also be carrying out cranial repair surgery, but it is not easy to really do this surgery well, and there are some patients in the clinic who have caused temporal concavity after cranial repair surgery. What is the cause of temporal depression after cranial bone repair? This should be considered from many aspects, such as postoperative temporal muscle atrophy; repair material factor; local external force strike and so on. Therefore, although cranial bone repair surgery is a routine surgery, it is a test of technical level, and it is necessary to find a regular professional medical institution and have the surgery operated by experienced and mature senior neurosurgeons. At present, our team uses the new PEEK material for surgery, which has excellent performance and avoids the defects of traditional materials, and is the ideal material for skull repair surgery because of its high postoperative comfort, protection and aesthetics. In addition, we also combine the actual, continuous improvement of innovative technology, the introduction of the concept of aesthetic plastic surgery, comprehensive development of PEEK cranial bone repair plastic surgery, and has been trusted and praised by the majority of patients.
