It is well known that if remedial measures are not taken in time after skull defect, not only the face value is greatly reduced, but also the intracranial pressure is unstable, and the cerebrospinal fluid circulation, blood circulation and various neurological functions cannot function normally, and some patients have dizziness and headache symptoms. Therefore, early cranioplasty has many benefits for appearance and all aspects of the body. In short, cranioplasty is the repair of a defective area of the skull with a suitable material by a neurosurgical specialist to restore the integrity of the skull. Before undergoing this procedure, patients should also be aware of the indications for the procedure. Generally, 3 months after debridement, a defect larger than 3 cm in diameter is considered an indication for surgery. Titanium mesh and peek material are the two most common materials used in clinical practice, but peek material is more effective in terms of stiffness, insulation, and longevity. The advantage of peek cranioplasty is that after the precise completion of the basic repair, some details of the shape can be perfected, and the postoperative effect of both sides of the skull can be symmetrical and aesthetic. This procedure is a major advancement and improvement for neurosurgery. Cranial repair is potentially reimbursable by medical insurance, but not all cranial repair procedures are reimbursable by medical insurance. It depends on the cause of the skull defect. Skull repair surgery is usually done three months after the cranial debridement and decompression surgery. If the cranial defect was caused by a car accident or a third party who caused the traumatic injury, the patient is responsible for the injury and cannot be reimbursed by medical insurance. If the patient had a cranial debridement surgery due to a fall or a brain hemorrhage due to hypertension or a large cerebral infarction, the patient is eligible for reimbursement. The cost of cranial repair is related to the material and the size of the bone window. Cranial repair surgery should be covered by medical insurance in most places, but this is subject to the regulations of each local medical insurance administration.
