The skull is a very important part of the human body in daily life, it plays an important role in protecting brain tissue, maintaining normal intracranial pressure, and keeping the aesthetic appearance. In life, due to traffic accidents, falls, natural disasters, surgical operations, etc., many people may cause defects in the skull, which require timely skull repair. Otherwise, there may be more serious adverse symptoms, such as unstable intracranial pressure, various intracranial life activities may be disturbed, which may manifest as headache and dizziness, in addition to the patient’s fear of pulsation, expansion and collapse of the defect area, and some patients show depression, fatigue, oligophrenia and low self-esteem Patients who have cranial defects are necessary to be repaired. Cranial repair is a relatively routine surgery in neurosurgery, and it is not difficult to do, but the key is the material. What is the best material for skull repair? At present, in some local hospitals, the more commonly used material for cranial repair is titanium mesh. In fact, besides titanium mesh, there are more ideal and suitable materials for cranial bone repair now. Currently, we are using polyether ether ketone PEEK cranial repair surgery, which not only achieves a single cranial repair, but also puts a lot of effort on the appearance of the plastic surgery, and conducts scientific analysis and research for each patient’s specific condition and signs, optimizes the design of the repair material, and develops a personalized and thorough cranial repair and appearance plastic surgery program, which ultimately achieves a beautiful appearance, anatomical integrity and The final result is the unity of aesthetic appearance, anatomical integrity and functional perfection with a low risk rate.
