The skull is a very important group of bones in the human body, located at the top of the human skeletal system, above the spinal column. The skull is composed of 23 bones of different shapes and sizes, which are very delicate to bite together to form a closed and complete cranial cavity, providing very important protection and support for the brain, intracranial soft tissues and head and facial organs, and also playing a very important role in the operation of the whole body and the whole life. However, we are exposed to various dangers in life, such as traffic accidents, production safety accidents, falling objects, fights and brawls, as well as our own cranial disorders, and craniotomy, etc. These factors may lead to cranial defects. After the occurrence of cranial defects, cranial bone repair surgery is needed in time. Cranial repair surgery is a relatively routine procedure in neurosurgery, and it is generally available in some large hospitals in many places. However, most of the repair materials used in most hospitals for skull repair surgery are titanium mesh materials, which may not achieve excellent repair results and may cause such and such problems after surgery. Many patients often choose to seek a better repair and receive better treatment. We use peek material for cranial repair, and we continue to improve and upgrade the technology, optimize the design of the material, and introduce the concept of aesthetic plastic surgery, and comprehensive PEEK cranial repair surgery, which has made great progress in improving comfort, improving blood flow, maintaining tissue activity, improving brain and nerve function, and enhancing aesthetics, which can achieve anatomical integrity, aesthetic appearance, and functional perfection. organic unity. Many patients with cranial defects from all over the country, under our careful treatment, have obtained good repair and achieved ideal results, with a new look after cranial repair and a much improved mood, spirit and psychology, reviving their confidence and starting a new life.
