What should I not do after cranial repair? Cranial repair is a common neurosurgical procedure to repair the skull in response to a traumatic brain injury that has resulted in a cranial defect. The longer the cranial defect, the higher the incidence of craniosynostosis syndrome and secondary brain damage. In order to restore the airtightness of the cranial cavity, maintain physiologic intracranial pressure stability, and alleviate cranial defect syndrome. Cranial repair should be performed in all cases where the diameter of the cranial defect is more than 3 centimeters, without muscle coverage and without contraindications. It is generally considered appropriate to repair after 6 months after craniotomy. Cranial bone repair is recommended to use appropriate repair materials, the current clinical application of the new PEEK material as a repair material, PEEK can completely restore the anatomical structure of the skull, in addition, this PEEK material is a bionic bone, can be highly compatible with the autologous skull, and in the elasticity, heat conduction, hardness, stability and other aspects of the performance of the autologous skull and autologous skull comparable to the performance of the children, especially for children, can be a better adaptation to the autologous skull, and can be used to repair the defects. Especially for pediatric patients, it can better adapt to the growth and development of the autologous skull. Of course, some of the precautions need to be noted after the cranial bone repair surgery, remove the line 1 month before you can wash your hair, do not scratch the repair parts of the skin to prevent infection, refrain from strenuous exercise, to avoid the impact of external forces on the repair of the cranial bone parts. In ordinary life, eat more protein foods, should quit smoking and drinking, eat a diet rich in high protein, vitamins and crude fiber, avoid spicy and irritating food, forbid smoking, alcohol, coffee, strong tea, reasonable arrangement of work and rest time, develop good habits, in order to promote the growth of the incision healing.
