Once the problem of skull defect occurs, what you need to do is to go to the hospital for skull repair surgery. The cost of skull repair surgery is also considered by many patients, but it should be noted here that the size of the skull defect of the patient is different, the hospital chosen is different, the repair material chosen is different and so on, all these will affect the cost of the surgery. At present, many local hospitals are using titanium mesh material for skull repair surgery, the price of this material is not high, and it is much more advanced than those traditional materials in the past, but there are many unavoidable problems, and many patients have various discomfort after the surgery. There is even a situation where the material is exposed, so that a second repair is needed, which costs more. However, medicine has progressed, and after the titanium mesh material, a new polymer material has emerged, which is polyether ether ketone material, commonly known as PEEK, which has excellent properties and high anastomosis, and can truly restore the integrity and beauty of the skull, without worrying about infection and discomfort after surgery. We use this PEEK material for cranial repair, incorporating the concept of orthopedic surgery, making the post-operative results more desirable and aesthetically pleasing. We have achieved excellent results and have been recognized and praised by our patients.
