What is the best time for cranial repair is when? Experts say that the traditional defect repair time is 3-6 months after cranial injury or craniotomy, while many scholars currently propose that cranial surgery, when the condition allows, advocates early cranial repair, that is, cranial repair within 3 months after surgery, which can better improve the prognosis of patients. For open skull fractures with more serious contamination alone, as well as open skull fractures with intracranial infection that may be infected, cranioplasty is recommended after the infection has been completely controlled for more than 6 months. Currently, although scholars advocate early surgery, it is still clinically felt to be more appropriate to repair after cranial injury, or 3-6 months after craniotomy. Can a skull defect be repaired after many years? Although the best time to treat cranial defects is between 3-6 months. But it does not mean that repair is not possible after this time. As long as there is no head infection and no serious heart or lung disease, skull repair is still possible. And it is recommended that the earlier it is done, the better. To avoid health risks. Can skull defect not be repaired Some people may ask, can skull defect not be repaired? I don’t feel any physical discomfort. Is it possible not to repair it? If skull defect is not repaired in time, it will cause various symptoms, which will endanger our health and also seriously affect our appearance. Some patients have headache, dizziness, and serious fear about the expansion and collapse of the defective part, which will cause depression and low self-esteem in the long run; some patients have poor self-control, concentration and memory loss. Moreover, long-term cranial defects can cause brain tissue atrophy and cystic changes. Therefore, for the sake of health, cranial repair is necessary. Cranial Repair Materials Cranial defects must be repaired, and the materials for repair must be carefully chosen. There are many kinds of materials for skull repair in the market, each with its own advantages and disadvantages, and there are many clinical examples of postoperative problems due to unsuccessful selection of repair materials. Although titanium mesh is an improvement over the previous traditional materials, it still has some shortcomings and defects. Fortunately, through the continued exploration and efforts of medical experts, polyether ether ketone, or PEEK as it is commonly known, has been the perfect solution to the shortcomings of other materials. The repair will not cause any rejection by the patient and will allow the patient to achieve the best possible recovery. Currently, PEEK has been used to repair cranial bones in clinical practice with excellent results.
