The skull is like a helmet that protects our brain all the time. However, we can’t predict and control the occurrence of accidents. Many people have suffered serious trauma to the skull due to an accident, and the brain tissue, without the protection of the skull, may be attacked by the outside world at any time, so we must not be careless. Cranial defects can cause a series of sequelae, and patients with minor injuries often feel dizziness, panic, chest tightness, slight sleep disorders and neurological disorders; patients with serious injuries may suffer from paralysis of limb functions, memory impairment and even dementia. Cranial defects are of great importance and require timely skull repair surgery. However, in cranial repair surgery, the choice of materials can directly affect the outcome of the surgery. The traditional materials include bone cement and plexiglass, which are inexpensive, but the postoperative results may not be ideal and have many defects, and they are gradually no longer used. Later on, titanium mesh material was gradually applied, which is also not expensive and has really improved a lot compared with traditional materials, but also inevitably has some problems and the results are not very satisfactory. In order to provide patients with better recovery results, our team has now introduced a more advanced and safe polymer material, polyetheretherketone PEEK. We have incorporated plastic surgery concepts into our procedures and many of our patients have been treated well. The full cost of skull repair surgery is determined by a combination of factors, including the area of the skull defect, the cost of materials, hospitalization, surgery, nursing care, medication, etc. We charge fees in strict accordance with the relevant national regulations, and patients with medical insurance can also receive reimbursement through the medical insurance process, which greatly saves treatment expenses.
