The skull is a very important part of the human tissue structure, and the intact skull builds the closed cranial cavity environment, but accidents always happen without warning, and the skull is severely traumatized, which will cause certain effects on the whole organism. Facing the problem of cranial defect, patients should realize its seriousness and go to the hospital to replace the cranial bone in time. The skull defect will not only affect the appearance, but also reduce the quality of life of the patient, and the patient will feel dizzy and headache from time to time, without any sense of security. If the skull defect is not repaired for a long time, the consequences will be even more serious if the defected part is accidentally hit twice. In medical science, it is necessary to do skull repair surgery to deal with skull defects, and it is an old and classic surgery without much risk, so patients do not need to have too much concern. However, a good repair material can greatly improve the success rate of the surgery and the post-operative effect; in addition, a more skilled and experienced senior doctor is needed to operate the surgery. At present, many hospitals in China are still using titanium mesh to repair the skull, how long is the service life of titanium mesh for skull repair? This is what many patients want to know, but in fact, there is no limit to the service life of the titanium mesh material itself, but if the patient has various complications after surgery, or if the deformation is caused by external collision, etc., it may need to be evaluated by the doctor and then remove the titanium mesh material and reschedule the surgery. In contrast to titanium mesh material, we use polyether ether ketone peek material is more advantageous, this is a very advanced polymer material, has high tissue compatibility, and its elasticity, hardness and strength are very good, the effect is very natural and beautiful We continue to summarize research, improvement and innovation, but also combined with the concept of cosmetic surgery, has a set of mature technical solutions, can achieve structural recovery, functional perfection, shape The overall unity of structure recovery, functional perfection and aesthetic appearance.
