Cranial defects are very common in neurosurgery and can be caused by natural disasters, traffic accidents or some cranial surgeries. Cranial defects are not a trivial problem because the skull plays a protective role for the brain, and once the integrity of the skull is destroyed, it means that the brain loses an important protective barrier and the normal functioning of the intracranial tissues will be greatly affected. Cranial defect affects the appearance, but more importantly, it may affect the patient’s brain function, leading to a series of cranial defect syndrome, such as headache and dizziness, some patients may have memory loss, concentration is also very unfocused, and appear to be abnormally agitated emotionally. If cranial defects are left untreated for a long period of time, the patients themselves may feel insecure, and if a secondary impact occurs accidentally, it may pose a threat to life safety. Cranial defects need to be actively treated and handled, and it is generally recommended that patients with defects larger than 3 cm should undergo cranial repair surgery before it is too late, so that a complete and closed cranial environment can be rebuilt as soon as possible to ensure that all intracranial life activities can function normally. Cranial repair surgery is an ancient and classic surgery, which has been developed and evolved for thousands of years, and the technology has been relatively mature, and it can be done in many local hospitals. However, in order to better improve the results of cranial repair surgery, it is especially important to choose a good repair material at the beginning. The ideal repair material in the clinic is a polyether ether ketone peek material, which is a new type of special polymer material, its various properties are very close to the autologous skull, and the postoperative recovery effect is good and aesthetic. What is the price of skull repair peek material? Many patients are worried that the price of peek material will be higher, but in fact, the specific cost of surgery varies from person to person, the size of the defect area is different, the cost is different.
