Accidental impacts in life can lead to the loss of human cranial bone. Once such an accident occurs, the brain tissue inside the skull loses its protective shell and comes into direct contact with the outside environment, and is also susceptible to infections from undesirable environmental assaults. Once the skull is damaged, the patient must go to the hospital as soon as possible to receive examination and repair surgery. Otherwise, it is easy to cause the patient’s own burden of thought, and may be accompanied by headache and dizziness and other symptoms. The longer the defect lasts, the higher the chance of secondary brain damage occurring. So when is the time for cranial repair? Repair surgery is performed after 3 months of cranial defect, during this time period, the pressure at the defect site is not high and there are no infections, ulcers or other factors that are detrimental to the healing of the incision. Therefore, this is the most pointed period for surgery. The ideal material for restoration is PEEK. The three-dimensional reconstruction technology of this material can perfectly restore the physiological structure of the skull according to the patient’s cranial CT data, and accurately fit the defective bone window. In addition, the performance of this material in terms of elasticity, thermal insulation, hardness, stability and other aspects is comparable to the autologous skull, which is a perfect cranial bone substitution material, and does not have a foreign body reaction, and will not affect the interference with the future radiological examination. It will also not affect the airplane, security check and so on. Warm reminder: the above is the detailed introduction of the time of cranial bone repair, I hope it will help you. It is recommended that patients go to regular hospitals as soon as possible to take appropriate treatment methods, active treatment, and early recovery of health.
