The skull, a solid bone in the human head, plays an important role in human life, not only to ensure the integrity of the skull at all times, but also to maintain normal intracranial pressure and a stable intracranial environment. However, in reality, there are always a lot of unforeseen accidents, resulting in many people with cranial defects. Skull defects are usually caused by traumatic brain injuries and lesions within the brain. Traumatic brain injuries are often caused by traffic accidents, natural disasters, and heavy objects. Lesions of the skull itself, most commonly cerebral hemorrhage and cerebral infarction, may leave a cranial defect after emergency debridement surgery. Long-term cranial defects are extremely harmful to the patient’s health and psychology. In some patients, the defects may appear as depressions or bumps, causing a series of cranial defect syndromes, which pose a serious threat to the patient’s health, and at the same time traumatize the patient’s psychology due to the extremely unattractive appearance. Neurosurgical guidelines clearly indicate that cranial defects of 3cm*3cm or more should be repaired as soon as possible when the patient’s condition is stabilized. Although cranial bone repair surgery in most general hospitals can be carried out, but because the operation involves the human scalp, blood vessels, brain tissue, nerves and other important organs, but also found that there are patients with postoperative complications such as rejection of infection, so the patient should not be taken lightly, we must choose the advanced and mature cranial bone repair technology. It is reported that polyether ether ketone peek cranial bone repair, with new high science molecular peek do implant material, take embedded repair way, smooth articulation after surgery, strong resistance to hit, low rejection infection rate. At the same time, we carry out personalized optimal design of the material and innovation and upgrading of surgical technology, introducing the concept of cosmetic plastic surgery, and formulate personalized cranial bone repair and cosmetic surgery plan for each patient to ensure precise postoperative repair, symmetry of both sides of the appearance of the natural and beautiful. How much does it cost to do a cranial repair? In fact, the specific cost of the surgery also needs to be based on the size of the patient’s defect area, the difficulty of the surgery, the presence or absence of other comorbidities, the specific treatment and care and other factors to be considered comprehensively.
