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 to the traditional materials, but again there are inevitably some problems and the results are not very satisfactory. The cost depends on the patient’s condition and various factors, including the area of skull defect, material cost, hospitalization cost, surgery cost, nursing cost, medicine cost, etc. We charge the cost in strict accordance with the relevant national regulations, and patients with medical insurance can get the corresponding reimbursement through the medical insurance process, which greatly saves the treatment expenses.
