In neurosurgery, cranial repair is a relatively simple and fast recovery routine surgery, although the technology has been very mature, but there are still some patients still have concerns about cranial repair surgery, in fact, this is not necessary, because there are many clinical cranial repair surgery after the feedback of good results in the case, as long as the choice of hospitals, choose the right materials, looking for a professional doctor for the repair can make the patient a good recovery. The results of craniofacial repair can be summarized in the following table. In recent years, cranial bone repair materials have been clinically used and improved, an advanced new polymer material polyether ether ketone PEEK appeared, making the cranial bone repair surgery safer, the effect is also more prominent. Last year, a girl from Shijiazhuang, due to falling objects were sent to the local hospital to do the bone flap decompression surgery left behind after the skull defect, and then came to repair, we are using this advanced polyether ether ketone PEEK material for her to the skull to complete the repair, not only the skull shape is very perfect after the operation, and a variety of neurological recovery is also very good. It is reported that this polyether ether ketone PEEK material, it has a traditional skull repair material does not have excellent performance, is currently highly recognized by the medical community, and in the country’s few public hospitals. First of all, the physical properties are very good, strength, toughness, elasticity, thermal insulation, stability and other aspects are almost comparable to the autologous skull, and the PEEK material does not interfere with the ray transmission, does not affect the postoperative acceptance of CT MRI and other examinations, three-dimensional molding and 3D printing technology with the restoration of the anatomical structure of the skull, precise anastomosis defective area, is the better choice for patients with cranial bone repair.
