According to research data, there are a large number of sudden accidents in our country every year, resulting in damage to the skull of many people. Without the protection of the skull, the intracranial tissues are vulnerable to external injuries, and if infections and other conditions occur, normal nerve function will also be affected. Technically, cranial bone repair surgery has a history of decades, and under the efforts of generations of medical experts, cranial bone repair technology has been perfected. Although cranial bone repair surgery as a kind of routine surgery of brain neurosurgery, the surgical method and detail treatment are different, and the postoperative results are very different. Currently, titanium mesh cranial bone repair is commonly used, because the implanted material is titanium metal and the surgical method is overlaying, which leads to many postoperative complications, such as infections, asymmetry of cranial shape, atrophy of temporal muscles, and even material exposure, and so on. With the progress of science and technology and the depth of clinical application research, a new polymer biomaterial peek has been gradually applied to the implant material of cranial bone repair, which provides more perfect material and technology for cranial bone repair surgery. Our PEEK cranial bone repair plastic surgery, after 4 technical innovations, has successfully completed hundreds of cases of PEEK cranial bone repair plastic surgery, experienced.PEEK cranial bone repair plastic surgery using embedded repair, high comfort, good protection performance, can fully aligned to cover the skull defect area; in the design, personalized material edge, to prevent wear and tear of the scalp. In the aperture design personalized improvement, increase blood flow, effective prevention of temporal muscle atrophy. Some patients with cranial defects ask how much does it cost to have peek cranial repair? For patients concerned about the price, the exact cost needs to be assessed based on the area to be repaired, the difficulty of the procedure, and other factors.
