Each organ of the human body has its own unique function and plays an irreplaceable role. As one of the important organs of the human body, the cranium not only plays a protective role for the human brain, but also has a vital role in the overall image of a person. Reasons for cranial defects: Nowadays, people often cause cranial defects due to various unavoidable factors, such as traffic accidents, falling objects, violent injuries, natural disasters, and some of the cranium itself may cause cranial defects, cranial defects, defective parts are directly exposed to the outside world, which is very dangerous, a little inattention may cause secondary damage to the skull, so timely repair, becomes particularly important. Therefore, timely repair becomes particularly important. PEEK material cranial bone repair plastic surgery: cranial bone repair surgery after years of development and improvement, has made great progress, at present, from the implantation of repair materials and repair method of the overall effect of peek material cranial bone repair plastic surgery better results. At present, Peek material cranial bone repair plastic surgery after hundreds of cases of pathology summary study, continuous improvement and upgrading of technology, currently realized four technical innovations, the material specific area thickness, mesh aperture design made further personalized improvement, conducive to the growth of blood vessel penetration, increase blood flow, prevention of temporal muscle atrophy, postoperative natural and beautiful; the material edge to increase the design of the notch, to prevent wear and tear of the scalp. In addition, in terms of plastic surgery, a personalized cranial repair and cosmetic surgery plan is developed for each patient to ensure the unity of symmetry, natural beauty, anatomical integrity and functional perfection of the postoperative shape. The cost of cranial bone repair: PEEK cranial bone repair how much does it cost, compared to the north, Zhengzhou cranial bone repair price is slightly lower, but the specific repair costs need to be based on the size of the patient’s defect area to decide, such as the defect area of 10 * 10cm cm patients and 15 * 15cm patients, the area is different, the cost of repair is different, so it is recommended that patients with cranial bone defects to the hospital to Therefore, it is recommended that patients with cranial defects go to the hospital to have a relevant examination and have the area of the cranial defect measured by the doctor before determining the cost of their surgery.
