However, some people in life because of an accident caused by the skull damage, the appearance of the image is not beautiful, the brain tissue in crisis, the situation is very urgent, need to go to the hospital in time to do skull repair surgery. Maybe many patients who do not know much about skull repair surgery will feel that the risk is very high, so they hesitate to go to the hospital. However, this will only delay the good time and put yourself in greater danger. Cranial bone repair belongs to neurosurgery, it is a routine surgical procedure that can be done in many hospitals, but how effective it really is still depends on the experience and skill of the experts as well as the choice of materials. When it comes to cranial bone repair materials, titanium mesh materials are widely used in many hospitals nowadays, but the results may not be as good as expected. Because the titanium mesh material itself has certain defects, some patients always have this and that problem after the operation, and even need to have another repair surgery, so it is not recommended to use it. With the development and progress of medical technology, there is now a new type of polymer material, i.e., peek material, which is the ideal material for cranial bone repair surgery. peek material makes up for the shortcomings of traditional materials, its performance is excellent, and generally do not have serious discomfort after the operation, and it can highly restore the structure of the human cranium.
