“The sky is the limit, and people may face all kinds of accidents from time to time”, every person may face all kinds of accidents. The head is the most important organ in the human body, and the skull, which protects the brain tissue of the head, is even more important. The reality is that many accidents, such as car accidents, cause a large number of patients to suffer cranial damage and require cranial repair surgery. Many patients are often caught in a dilemma because of their family’s finances, as they need surgery to bring about good health, but are also concerned about the high cost of cranial repair surgery, and do not want to put a heavier burden on themselves and their families. In fact, the patient’s worry is a bit superfluous. Because although the skull is an important organ, but the skull repair is only a neurosurgery routine surgery, and does not belong to the category of difficult surgery. For experienced doctors, it is a breeze and the risk is not too high. As for the price of the surgery, it cannot be equated with commercial products. Some skulls are large, some are medium, and some are only small, and there is a big difference in the cost. In addition to this, the choice of repair material is also crucial in determining the cost of the procedure. The most widely used traditional titanium mesh has a relatively inexpensive material cost, so many local hospitals and general hospitals choose this material to operate on their patients, and the patients are more than satisfied with the price. However, titanium mesh material has obvious clinical defects. The common hot and cold sensitivity reaction will make patients have chronic pain symptoms after surgery, and some patients take long-term medication to link the pain sensation. The polyether ether ketone (PEEK) material chosen for cranial bone repair is an internationally recognized cranial bone “replacement” material, and is therefore relatively expensive. As the saying goes, “you get what you pay for”, which is not a gross statement. In terms of biocompatibility, PEEK is far superior to titanium mesh, modulus of elasticity, strength, thermal insulation, stability are similar to the autologous skull, the use of three-dimensional molding production of the ancient plate, can be accurately matched with the original cranial structure, which is the key to the success of the operation.
