Cranial repair is the process of artificially repairing the defective skull by surgical methods after cranial defects caused by various reasons in life. The main role of cranial repair is to protect the soft tissue of the brain, eliminate the psychological shadow caused by cranial defects, and restore the normal state of brain tissue, thus improving the quality of life of patients. The main etiology of cranial repair is cranial defects caused by cranial trauma and intracranial diseases and other craniotomy procedures. If the injury site has intracranial infection, hydrocephalus, brain swelling and other symptoms, cranial bone repair can be delayed to prevent infection after autologous or allogeneic implantation.PEEK material (polyether ether ketone) is a semicrystalline thermoplastic material, which is resistant to high temperature, chemical resistance, fatigue resistance, has excellent strength hardness and toughness, and is a more ideal material for cranial bone repair. After numerous clinical feedback, polyether ether ketone material for cranial bone repair, various complications, sensitivity to hot and cold reactions, subcutaneous fluid accumulation and other problems. Moreover, PEEK material is 3D printed to precisely fit the defect area, restoring the original craniomaxillofacial appearance and meeting the requirements for aesthetics. How much does it cost to have a craniofacial repair? The cost of surgery is closely related to the materials used for repair. Good materials have better repair results and better post-operative recovery, and the cost may be slightly higher.
