Is it necessary to repair a cranial defect? Cranial defects are often caused by accidents, brain diseases, and other surgeries, and the top of the head collapses or bulges out. Once a skull defect occurs, if it is not repaired for a long time, the patient may have various adverse reactions such as dizziness, headache, pain at the edge of the defect, and may cause fear, depression, and low self-esteem, so the impact of a skull defect is still relatively large. Therefore, cranial defects (3 * 3CM or more) must be repaired as soon as possible, for the time of cranial repair, here to give you a detailed explanation: the better time for cranial repair surgery is generally in the postoperative period of 2-3 months, some patients can also be based on their own medical conditions to determine the time of the repair, and at the same time, the choice of repair materials are also related to the overall shape of the postoperative period and the rehabilitation situation, a good material! A good material will not only provide a good recovery, but also avoid some postoperative complications as much as possible. For cranial repair materials, most hospitals still use titanium mesh as the repair material. According to clinical patients’ postoperative response, titanium mesh is not only exposed after surgery, but also because it is a metal material, patients are easy to be sensitive to hot and cold stimuli after surgery, and it is easy to produce or store fluid in the subcutaneous tissues that can easily be infected, and the lesion localization may be uncomfortable or chronic pain. Such as temporal fossa, eyebrow frame and other special parts of the repair after the appearance of poor results and so on. With the unremitting efforts and exploration of medical experts, a new high-tech materials can be very good to meet the basic requirements of patients for cranial bone repair, the material is polyether ether ketone PEEK material, PEEK material has a high temperature resistance, corrosion resistance, ray transmittable, can be complex shaping advantages, and can be well avoided after the operation of the titanium mesh and other materials exist in the complications, so that many patients in the postoperative period are better able to recover. The material has the advantages of high temperature resistance, corrosion resistance, radiation permeability, complex shaping, and can avoid the complications of titanium mesh and other materials after surgery.
