Cranial repair hand is for cranial defect is a partial defect of the skull, losing the original complete shape of the skull, caused by congenital developmental abnormalities or acquired sudden factors, mostly due to cerebral hemorrhage and cranial hypertension surgical decompression surgery or surgical resection of cranial lesions. The disease may manifest as headache, dizziness, loss of muscle strength, etc. Patients with cranial defects should be prepared to undergo surgery, and choosing good repair materials and surgeons can guarantee the success rate of the surgery. So, is cranial repair surgery an open-heart surgery? First of all, cranial repair is not a craniotomy. The surgery is usually done under general anesthesia because the surgery is only done outside the brain tissue, so the risk is not high and there are usually no after-effects. The dura mater has not been opened to enter the brain, but only to separate the skin and place the repair material under the skin. In medical terms, a craniotomy in the strict sense should be considered as opening the skull into the dura mater afterwards. Therefore, it is not a major surgery for neurosurgeons, but for patients or families, it may be more psychologically stressful. However, if we understand the procedure, we can know that the cranial repair surgery itself is very low risk, close to a cosmetic surgery, and early cranial repair surgery can help patients return to society and work early after surgery. Here I will briefly explain the cranial bone surgery procedure to you. Cranial repair surgery process 1, first need to 3D CT scan of the patient’s skull, extract accurate 3D data, 3D reconstruction, 3D printing to produce a personalized PEEK repair material that perfectly fits the structure of the bone window. 2.The scalp is incised during the surgery, and the layers of tissue are carefully separated to expose the bone window, and then the material is precisely affixed to the bone window and adjusted and reset. 3, well fixed with special lap screws, suture all layers of skin, and the surgery is complete. 4.After the operation, pay attention to give antibiotics to prevent infection, hemostasis and neurotrophic drug treatment; pay attention to observe the changes of the patient’s surgical cavity drainage, change medication regularly and observe the healing of the incision.
