It is a difficult thing for every patient to face. The brain tissue loses its strong protection and affects the aesthetics of the skull at the same time. Many patients who have injured their skull by accident want to regain their health through surgery. Modern medical technology is advanced and skull repair surgery is gradually becoming a routine neurosurgical procedure. Many patients are also willing to actively undergo surgical treatment after understanding and comparing. Damage to the skull is a difficult thing for every patient to face. The brain tissue loses both strong protection and the aesthetics of the skull. Many patients who have damaged their skull by accident hope to regain their health through surgery. Modern medical technology is advanced and skull repair surgery is gradually becoming a routine neurosurgical procedure. Many patients are also willing to actively undergo surgical treatment after understanding and comparing. The preoperative anesthesia and sterilization are no different from the regular surgery. During the surgery, the surgeon will cut the scalp at a suitable location and bluntly separate the periosteum according to the damaged part, shape and size of the skull. The exposed bone window is clearly visible after hemostasis of the surgical field. The surgeon takes the preoperative three-dimensional plasticized bone plate repair piece, adjusts the shape according to the physiological structure of the damaged area, fixes and resets it, and then sutures the scalp layer by layer. A successful skull repair was completed. After listening to the doctor’s introduction, patients feel that cranial bone repair is like a simple minor surgery, but in fact, it is not quite true. Although this is a routine surgery, any surgery involving vital organs of the human body should not be taken lightly. The surgery requires a high level of clinical experience and the ability to deal with all possible risks during the operation. The current clinical application of a polymer PEEK material as a skull repair surgical material has greatly improved the success rate of the surgery and achieved good clinical results, which are recognized and appreciated by patients.
