The ideal cranial bone repair material must have the following conditions: ① easy to shape and fix; ② small tissue reaction, non-toxic; ③ chemically stable, not corroded, absorbed and aged in the tissue; ④ able to pass through X-rays; ⑤ no heat transfer, non-conductive; ⑥ light texture and sufficient mechanical strength. Currently applied cranial bone repair materials mainly include: 1. Autologous bone, mainly autologous cranial bone preserved after the first surgery, which is free of foreign body irritation, small reaction and good postoperative healing process. Due to preservation problems (infection, cranial bone resorption), it is more difficult to carry out in many units. 2, non-metallic materials: commonly used are polymethacrylate methacrylate (i.e. plexiglass), its toughness is stronger, not easy to break, chemical properties are stable, not easy to corrode, non-toxic, easier to shape, accurate to maintain the plasticity after cooling, a poor conductor of electric heat, can pass through X-rays, easy to postoperative inspection, simple plastic procedures, easy to take materials, defect size trait in the choice of not limited, light postoperative tissue reaction. However, after the emergence of better titanium mesh material and polyetheretherketone material, this material also withdrew from the stage of history. 3, titanium mesh material: commonly used metal material titanium alloy plate. It is easy to shape, light tissue reaction, good appearance and high cost performance. It is a better material for cranial repair, and it is one of the preferred repair materials at present because of higher anastomosis and better effect after computerized three-dimensional shaping. 4.Polyether ether ketone (peek) material has been used in Europe and America several years ago, so far, there are more than ten years of clinical experience, which can well avoid the problems of titanium mesh skull repair. In addition, polyether ether ketone peek material cranial bone repair plastic surgery in surgery using embedded repair, smooth articulation, high comfort, effectively avoid abrasion of the skin, the material exposed and other problems. In addition, after years of clinical summary, our neurosurgery department adopts unique material thickness and mesh aperture design in three-dimensional design as well as unique tissue separation and repositioning technology during surgery to effectively avoid temporal muscle atrophy and ensure the activity of each tissue, which can effectively ensure the overall beauty of postoperative appearance.
