Some people have skull defects in their lives for one reason or another, which not only damage their image, but also seriously threaten their health and safety. Cranial defects have to be repaired by skull repair surgery to help reduce the damage. So, what is the best way to recover after skull repair surgery? Skull defect, brain tissue because of the lack of cranial protection, resulting in extra-cranial atmospheric pressure will act directly on the brain tissue, seriously damaging the patient’s brain function. Moreover, the temperature outside the skull also affects the brain tissue, and the uneven heat and cold are not conducive to the recovery of brain nerve function. Patients are worried, but in order to get a better recovery, patients should not have too much psychological burden, cranial defects are indeed very harmful, but as long as they receive an effective cranial repair surgery at the right time, the brain nerve function will be significantly improved after the repair. The current material for repairing the skull is polyether ether ketone, or PEEK, which is a very advanced and ideal material for cranial repair. In addition, this PEEK material is bionic bone, which is highly compatible with the autologous cranial bone, and is comparable to the autologous cranial bone in terms of elasticity, heat transfer, hardness, and stability. Of course, we should do a good job of postoperative care, as the saying goes, medicine is better than food. As the saying goes, medicine is better than food. For patients with cranial bone repair, the diet should be light, especially avoiding coffee, strong tea, chocolate and other refreshing foods. More fruits and vegetables in season can promote the growth and healing of the wound. It is recommended that patients should have skull repair in time after skull defect, and it is very important to choose the appropriate repair material. After the operation, we should pay attention to the above precautions and develop good living habits to help our health.
