Cranial bone repair is required after a defect is sustained in the skull, and can be very harmful if not performed in a timely manner. Because of the lack of structural support on the defective side of the skull, brain tissue often bulges, collapses, or alternating bulge-submergence phenomena. Frequent displacement of brain tissue can lead to further damage to the fragile brain tissue and severe occurrence of entrapment causing cerebral ischemia or cerebral infarction. Brain tissue that has lost its structural support often collapses and compresses normal tissue, resulting in ongoing effects on normal tissue. The most important things for patients are the risks of surgery and the price of surgery. Cranial repair surgery is a routine treatment often performed in neurosurgery and is not very difficult or risky and is critical to the patient’s recovery later in life. As for the price, the price of cranial bone repair depends on the composition of the material, currently there are traditional titanium mesh and the more advanced PPEK material on the market, the titanium mesh does not fit well with the autologous bone, so the price is cheaper, PEEK material is close to the autologous bone in hardness and adaptability, can be highly compatible with the autologous bone, the price is naturally a little more expensive.
