The skull is like a door to the brain, if the skull is defective and the door is not closed, the intracranial tissues are bound to be threatened by the outside world. Many people are left with cranial defects because of an accident or craniotomy due to craniosynostosis. If the skull defect is not repaired for a long time, the defective part will collapse or deform, and the patient will feel inferior. Of course, more importantly, the skull defect will affect the health and safety of the patient, and once the bump occurs, it will directly hurt the brain tissue and endanger the life. Will the right occipital lobe skull repair affect the nerves? This is what many patients are worried about, they are afraid that skull repair surgery will affect the nerves of the brain, but in fact, skull repair surgery is a very mature technique in neurosurgery, and the safety is very high. The skull repair itself is done outside the brain and will not hurt the brain nerves. And after the repair, the nerve damage previously suffered by the patient can be improved to some extent. Only safer and advanced materials can achieve better repair results and lower chances of post-operative complications. For example, many hospitals now widely use titanium mesh material, although it is much more advanced than the past material, but there are still some problems and shortcomings, the more serious is the phenomenon of material exposure. In fact, there is now a new polymer material, that is, our team is now widely used PEEK material, its performance is excellent, to make up for the shortcomings of the titanium mesh material. We have also incorporated the concept of cosmetic surgery, and the post-operative results are more natural and beautiful, and are well received by patients and families.
