Cranioplasty is a common surgical operation in neurosurgery. Titanium mesh is a kind of skull repair material widely used in neurosurgery. Many patients with skull defects choose titanium mesh to completely restore their heads. The service life of titanium mesh depends on the patient's postoperative recovery. Some patients with titanium mesh repair may have no discomfort after operation, and the titanium mesh is not exposed. In this case, it can basically be used for life. Then some people's skulls repaired with titanium mesh are infected or deformed under the action of external force several months or years after operation, resulting in exposure. In this case, you may face the problem of material substitution. It is suggested that patients go to the hospital for symptomatic treatment at the first time, and then the doctor should further consider the material substitution problem as appropriate.

At present, the more advanced and ideal skull repair material is PEEK. The application of this advanced material in neurosurgery has achieved ideal results after long-term clinical practice. PEEK material can copy the part of human skull defect. Based on CT data, the advanced 3D printing technology is used to reconstruct the design, which is consistent with the defect area and meets the high requirements of patients for the repair of the defect area. PEEK material has good histocompatibility, stable chemical properties, elastic modulus and cortical bone, and will not sag and deform even if it collides, which plays a vital role in skull repair surgery.

Peek skull repair and plastic surgery are now widely carried out. It is an advanced and mature technology, which combines the advanced peek implant and the concept of cosmetic plastic surgery. It can be used for life through one repair, and the appearance effect is more prominent.
