Cranial repair is a routine procedure in neurosurgery, but it is not easy to do really well. Both the repair material and the surgical technique govern the final outcome of the repair, and no matter which part of the process is not in place, problems can occur. Some patients then ask what are the common problems that occur after cranial repair surgery. There are still many general hospitals using titanium mesh material for skull repair. Titanium mesh as a material for skull repair has certainly made some progress compared to those materials such as silicone, bone cement, plexiglass, coral, ceramic, etc., but its performance is still not very satisfactory, and some problems may occur, such as postoperative infections, rejection, abrasion of the scalp, exposure of the material, collapse and deformation under stress, affecting CT and MRI examinations, and poor contouring results. Magnetic resonance examination, poor molding effect and so on. Of course, at present, some hospitals have gradually started to use a new type of polyether ether ketone PEEK material, PEEK is really a very good cranial bone repair material in recent years, is a special polymer material, with excellent performance, in terms of hardness, strength, elasticity, thermal insulation, histocompatibility, radiation transmissibility, compatibility with magnetic fields and other aspects of the performance of the human autologous cranium is very close to the human body, it can be said that the ideal material for cranial bone repair is very close. It can be said that it is the ideal material for cranial bone repair. However, good materials also need good techniques to get good results. Some local hospitals are not experienced and technologically immature, even if the use of PEEK material may inevitably have such and such problems, such as temporal muscle atrophy and sagging, resulting in muscle buildup on one side of the head asymmetry, such as the exposure of PEEK material and so on. Therefore, in addition to choosing a good repair material, patients also need to find a skilled and experienced senior professional physician to complete this surgery. At present, we have introduced PEEK cranial bone repair material earlier, and our team keeps on optimizing the design of the material and improving and upgrading the technology, at present, we have four technological innovations, unique thickness of the material, mesh aperture design, edge groove design, unique tissue separation and restoration technology, temporal muscle suspension and fixation technology, etc., which can effectively prevent the emergence of various problems in the postoperative period, and achieve the ideal repair effect, which is highly praised and acclaimed by the majority of patients and their family members. It is highly praised by patients and their families.
