Due to the occurrence of various dangerous accidents and various cranio-cerebral surgeries, the incidence of cranial defects has gradually increased, and now cranial defects have become a common disorder. Cranial defects can be very harmful, putting the brain at risk and making it more susceptible to external aggression; changes in intracranial pressure and intracranial environment can also cause a series of neurological symptoms; and cranial defects can also affect the aesthetic appearance. First of all, our PEEK cranioplasty is made of the new PEEK material, which is much better than the traditional titanium mesh material. Compared to traditional titanium mesh materials, PEEK is biocompatible and has a lower chance of rejection and infection; PEEK is mechanically strong, hard and flexible, and will not be deformed by external forces. In addition, the PEEK cranioplasty procedure has been upgraded in terms of material design and technique to provide greater advantages over traditional titanium mesh repairs and conventional PEEK repairs. The team has continuously summarized and researched and improved hundreds of repair cases in the past, and now has four technical innovations, including personalized design of the material edges, thickness, and mesh apertures to prevent scalp abrasion, ensure adequate blood flow after surgery, and prevent temporal muscle atrophy; fine separation of all layers of tissue during surgery, complete reset after surgery, and ensure tissue activity; introduction of aesthetic plastic surgery technology, and personalized and appropriate treatment of factors affecting aesthetics to ensure that the surgery is performed properly. The introduction of aesthetic plastic surgery technology, personalized and appropriate treatment of factors affecting aesthetics, to ensure the natural beauty and symmetry after surgery, etc. The cost of the surgery is determined by the area of the defect, the size of the material, the cost of the examination, etc. Of course, the cost will be reimbursed according to a certain percentage, and the patient will not have to bear high costs.
