The skull is like a door to the brain, and if the skull is defective and the door is not closed, the tissues inside the skull are inevitably threatened by the outside world. There are too many patients with cranial defects in the clinic, and many of them will be left with cranial defects because of an accident, or because of craniocerebral diseases that require craniotomies, and so on. The appearance of patients with cranial defects will be very affected, and if the defects are not repaired for a long time, the defects will also be collapsed or deformed, and the patients will feel inferior as a result. Of course, more importantly, cranial defects will affect the patient’s health and safety, once the bump, will directly hurt the brain tissue, life-threatening, the patient must pay attention to timely go to the hospital for cranial bone repair surgery. Will the right occipital lobe skull repair affect the nerves? This is what many patients are worried about, they are afraid of the cranial bone repair surgery will affect the brain nerves, but in fact in neurosurgery cranial bone repair surgery is a very mature technology, the safety is very high. The skull repair itself is done outside the brain and will not hurt the brain nerves. Moreover, the damage to the brain nerves previously suffered by the patient can be improved to a certain extent after the repair. However, in addition to a good expert doctor, the repair material is also important for cranial bone repair surgery. Only safer and advanced materials can achieve better repair results and lower chances of postoperative complications. For example, many hospitals are now widely used 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 that the material will be exposed phenomenon. In fact, there is now a new type of polymer material appeared, that is, our team is now widely used PEEK material, its various properties are excellent, to make up for the shortcomings of the titanium mesh material. Moreover, we have also combined the concept of aesthetic plastic surgery, and the postoperative effect is more natural and beautiful, which is highly praised by patients and their families.
