“Cranial repair” is a routine surgery for cranial defects caused by trauma and craniotomy. The main purpose of the surgery is to protect the soft tissues of the brain and prevent complications. The choice of repair material for cranial repair surgery is also very critical. The choice of cranial repair material must first be highly biocompatible and the repair material must be sufficiently resistant to blows, as well as perfectly shaped. PEEK is the most perfect combination of toughness and rigidity of all resins, and its strength and fatigue resistance are even better than those of some metals and alloys as a cranial repair material. Because PEEK is a resin that is not toxic, its molecular structure is very stable and histocompatible, and PEEK materials do not react to heat or cold and will not burn or frostbite the soft tissues of the brain in high or low temperature environments. The PEEK material has excellent self-lubrication and wear resistance and will not wear the skin of the head after surgery, and there will be no leakage of the repair material, making it the ideal material for skull repair. As a routine procedure, is skull repair reimbursed by the New Rural Cooperative? The cost of repair surgery is reimbursed by the New Agricultural Cooperative for rural basic medical insurance, and the reimbursement base is based on the local reimbursement policy. If patients have medical insurance, they can be referred to the hospital directly. At present, most hospitals have realized the national medical insurance network, so as long as they are referred to the hospital, the patients can enjoy the medical insurance policy and the reimbursement process is very convenient.
