Various organs of the human body are indispensable for good health. However, life is full of accidents, which can cause damage to our body organs. Cranial damage is a relatively common problem, and this is directly related to the life and health of a problem, once the skull is damaged, only cranial repair surgery can ensure that the brain tissue in the skull to operate normally. When it comes to cranial repair surgery, patients will worry about the cost of cranial repair surgery in addition to the fear. What are the costs of cranial repair surgery? The cost of cranial repair surgery includes preoperative examination cost, hospitalization cost, surgical cost, material cost, and so on. Moreover, different patients have different sizes of damaged area of the skull, the cost is also different, and the cost will naturally be higher if the damaged area is large. However, the materials used in skull repair surgery basically take up a significant portion of the cost. There are many materials to choose from, including traditional human bone, plexiglass, and bone cement, all of which are inexpensive, but have been gradually phased out because of postoperative problems. The more popular titanium mesh material, the price is not very high, but a lot of clinical trials have shown that the use of titanium mesh material for cranial bone repair surgery will have more complications, and the titanium mesh is a metal material, not insulated, the patient will have a lot of discomfort after the operation. In addition, the use of titanium mesh for cranial bone repair surgery does not have an ideal postoperative contouring effect, and it can interfere with future medical examinations. Because of the defects of these traditional materials, we now use a more advanced new material, namely PEEK material, which is a real polymer biomaterial, the performance is comparable to the human skull, and the postoperative shaping effect is quite perfect. In terms of aesthetics, stability and hardness, PEEK is superior enough.
