According to research data, there are a large number of sudden accidents in China every year, resulting in many people with cranial damage. Without the protection of the skull, the intracranial tissues are susceptible to external damage and can affect the normal neurological function if infections and other diseases occur. Technically, cranial bone repair surgery has been performed for decades, and with generations of medical experts’ hard work, cranial bone repair technology has been very well developed. Although cranial repair is a routine procedure in neurosurgery, the surgical approach and detailing vary and the postoperative results vary greatly. The titanium mesh cranial repair is commonly used at present, because the implant material is metallic titanium and the surgical method is overlay, which leads to many postoperative complications still, such as the occurrence of infection, asymmetric skull shape, temporal muscle atrophy, and even material exposure. With the advancement of science and technology and clinical application research, a new polymeric biomaterial peek is gradually applied as the implant material for cranial bone repair. The medical application of this new polymer biomaterial called PEEK has greatly compensated for the shortage of materials for cranial prosthetics. Using PEEK material, the material itself also has excellent bionic properties, high thermal insulation, good stability, and high compressive strength, making it an excellent material for cranial bone repair from any aspect. Through the improvement of technology and optimization of materials, the care and recovery time of cranial bone repair surgery is greatly reduced. Our experts say that generally speaking, if PEEK material is chosen, and no other medical conditions exist, you can generally move freely in three days after surgery. The doctor’s instructions for rehabilitation will be followed for a week before you can be discharged from the hospital to recuperate. Follow the doctor’s instructions to take more rest and eat a light diet, half a month to a month’s time to achieve full recovery.
