The frequency of traffic accidents is high, and it is often these accidents that lead to the prevalence of cranial defects, and of course, cranial defects are not uncommon after some craniofacial surgeries. However, regardless of the cause, the danger of cranial defects is great and must be actively addressed and dealt with. After skull defect, patients will often feel dizzy and headache, become very insecure, have low self-esteem, and become easily agitated, and even have epilepsy and some mental disorders. Cranial defect should be taken seriously, and it is rarely possible for cranial defect to heal by itself, especially for some patients with large defect area, the more effective way is to do cranial repair surgery. However, an important factor in the effectiveness of skull repair surgery is the choice of materials. Currently, titanium mesh material is widely used, but it has been proved that it has some disadvantages and shortcomings, and there are more postoperative problems. In fact, in addition to titanium mesh material, the new polyetheretherketone peek material we use now is safer and more effective, and its performance is very close to that of autologous cranial bone, effectively avoiding the shortcomings and shortcomings of titanium mesh material, and the postoperative recovery is ideal. Of course, in addition to the material, the physician’s experience and technical skills are also very important, our team continues to improve and innovate technology, and now the skull repair and plastic surgery has been more mature and perfect. How much does a peek skull repair cost for 40 square centimeters? The repair effect of peek material is really good, the price is also more expensive than the previous material, which makes many patients are more worried. But in fact, compared to the cost, the effect is more important.
