The skull is a very hard set of bone tissue that plays a key role in protecting the human brain, and it can even be said that it acts as a bulletproof vest for the brain from outside dangers that could harm it. However, accidents can lead to skull defects, where the brain loses its vital protection and the intracranial tissues are at risk. The intracranial environment changes dramatically after a skull defect, the intracranial pressure becomes unstable, the cerebrospinal fluid circulation and the blood circulation are affected, and the cerebral nerve function is also damaged, causing a lot of physical discomfort to the patient. If the skull defect is not repaired in time, and the defective part of the skull is accidentally hit again, it will be life-threatening. Cranial defects should be actively treated, the more effective way is to do skull repair surgery, which is a routine surgery, technology is relatively mature, safety is also relatively high, but if the repair material is not selected, the postoperative recovery effect is still a great impact, so patients should be more cautious. At present, many hospitals use titanium mesh material, although the titanium mesh material also has some progress, but there are always some inevitable problems, such as postoperative wear and infection, force collapse and deformation, affecting the ct nuclear magnetic examination, and even the phenomenon of material exposure. Once material exposure occurs, it is important to have the surgeon do a specific evaluation and then reschedule the surgery to refinish the repair. Is there any risk of re-patching after cranial repair? No. It is basically not a problem to go to a regular hospital and have an experienced surgeon arrange the treatment. We perform a wide range of cranial repair surgeries here, including revision surgery after a failed repair in an outside hospital. The team uses the new polyetheretherketone peek material to carry out surgery, the peek material’s various properties are very excellent, to make up for the lack of titanium mesh material, and we continue to improve the technology innovation, but also introduced the concept of cosmetic plastic surgery, comprehensive development of the peek craniofacial repair and reconstruction, and achieved very good clinical treatment results.
