If people compare the brain to the “commander” of the human body, then the skull is the bodyguard that protects the “commander” at all times, which is a very apt description. Because the biggest role of the skull is to protect the brain tissue and maintain the intracranial pressure so that the brain can function normally. However, there are many things that we cannot predict, some people have serious skull damage due to falling objects or traffic accidents, so it is important to have skull repair surgery in time. Before doing skull repair surgery, the choice of material is an important factor that affects the postoperative effect. Titanium mesh titanium mesh skull repair sequelae are mainly as follows 1.There are a lot of data showing that using titanium mesh material to do skull repair surgery, postoperative patients may have infection and will have some discomfort. 2, titanium mesh material is used in the repair surgery in a covered way, so it will stimulate the patient’s scalp a lot and cause a series of complications easily after the surgery. 3. The hardness of titanium mesh is not large enough, so it is easy to produce deformation if it is stressed. 4, titanium mesh is a metal material, the thermal conductivity of metal is relatively strong, the patient’s head will be very sensitive to hot and cold reactions after surgery. 5, at the same time, because the titanium mesh is a metal material, the postoperative review, this metal material will affect the examination images, interfering with the doctor’s diagnostic results. The biocompatibility of titanium mesh material is not so good, and if the incision does not heal well after surgery, it is easy to have material exposure or even hydrocephalus and hematoma, which is very serious. It is not difficult to see that actually using titanium mesh for skull repair surgery is not very good. Our traumatic cerebrovascular disease neurosurgery team is doing a great job of overcoming these problems by using a much better performing polyetheretherketone PEEK material. Our team uses the new polyetheretherketone PEEK material, and constantly makes technical improvements and introduces the concept of aesthetic plastic surgery, while carrying out PEEK cranial repair plastic surgery, which has achieved outstanding clinical results, not only to achieve the physiological anatomical repositioning of the skull, but also to ensure the activity and functional perfection of all layers of tissue, and also to ensure the natural beauty of the skull shape, which is highly recognized and praised by patients.
