In today’s world, things don’t always go as planned, and after a car accident, impact, intracranial disease, or other surgery, there is a chance that the skull may become deficient and the top of the head may collapse or bulge out. Patients with cranial defects need to undergo cranial repair surgery as soon as possible after they have recovered from surgery. Currently, titanium mesh is the most commonly used repair material, but some patients have experienced some discomfort after the repair surgery, which has deterred more patients from undergoing the surgery. The emergence of a new material, peek, has given patients with cranial defects a ray of hope. The cost of cranial repair is inextricably linked to the choice of repair material, the overall strength of the hospital and the skill level of the doctor. At present, some places do not pay much attention to cranial repair, and many of them still stay in the stage of repairing the skull with titanium mesh. Although the price of titanium mesh material is relatively low, but for the patients who are allergic to the titanium mesh, the phenomenon of rejection may occur after the operation; in addition, due to the embedded titanium mesh material, the patients may have the titanium mesh exposed after the operation and other situations. For the titanium mesh and traditional materials in the cranial bone repair of the current situation of the effect is not ideal, we carry out polyether ether ketone peek material cranial bone repair plastic surgery, the use of peek as a cranial bone repair implantation material, and achieved good therapeutic results. Although the price of this material is a little more expensive, but all the properties are very excellent, is the current ideal material for cranial bone repair. At the same time, for patients who do not have cranial defects, the hospital also formulates personalized and thorough cranial repair and cosmetic surgery plans, which ultimately achieve the unity of beautiful appearance, anatomical integrity and functional perfection.
