In the human skeleton, the skull is the hardest, it is the hard shell to protect the human brain. However, even if the skull is hard, it can not withstand the impact of some external gravity, and inevitably such problems as cranial defects. Once the human skull is damaged, the brain tissue lacks proper protection and the situation is quite dangerous. Skull defect, affecting health and aesthetics It must be clear that after skull defect, the intracranial pressure is extremely unstable, which will directly affect the circulation of cerebrospinal fluid and blood in the skull, making it difficult for brain tissues to function normally, and it is also very unattractive from the appearance. Therefore, it is necessary to perform skull repair surgery in a timely manner, both from a health perspective and aesthetically. The titanium mesh material commonly used in clinical practice is not ideal. The choice of material is a crucial aspect of skull repair surgery, and good material can achieve more ideal repair results. Titanium mesh material is widely used in some local hospitals today, which is an improvement over traditional bone cement and plexiglass, but some defects cannot be avoided. The most common are postoperative infection and rejection, and even scalp tissue damage, and the heat insulation of titanium mesh is not very good, so patients may become sensitive to hot and cold environments after surgery. Titanium mesh affects MRI, but PEEK does not. Can I do MRI with titanium mesh for skull repair? This is also a critical point, because titanium mesh is a metallic material that can interfere with radiation transmission and affect postoperative CT MRI and other examinations, interfering with the final diagnosis. Therefore, to better perform cranial repair surgery, a more advanced high-tech material is needed, polyether ether ketone – PEEK material is a good choice, the performance of this material is very good, and equivalent to the autologous cranial bone, postoperative do not have to worry about infection problems, and do not worry about interference with the relevant medical examination. PEEK Cranioplasty Currently, our traumatic cerebrovascular neurosurgery team uses PEEK to perform cranioplasty. We use PEEK material with excellent performance, and we continue to innovate and upgrade our surgical techniques and introduce the concept of cosmetic surgery to achieve good repair results, achieving structural integrity, functional perfection, and aesthetic appearance, with a wealth of clinical cases and highly recognized postoperative results.
