Cranial repair is a relatively routine procedure in neurosurgery, and the technique is well established. At present, it is very important to choose appropriate repair materials in cranial bone repair. A good repair material can achieve a more ideal repair effect and reduce the incidence of postoperative complications; if the repair material is not properly selected, various problems may arise. Some patients ask if peek is strong enough to repair their skull? Is it better than titanium mesh? This patient’s question is typical, at present, the clinical repair material used to repair the skull, the main two – titanium mesh and peek. clinical more widely used cranial bone repair material is titanium mesh. It is a relatively traditional cranial repair material and has been used for a long time, with a history of 20 to 30 years. Compared to earlier materials, titanium mesh is advanced. However, there are still some defects and shortcomings of this kind of metal mesh material, such as postoperative infection, rejection, wear and tear of the scalp, resulting in the exposure of the material; titanium mesh insulation is not good, the patient’s sensitivity to the external environment of the hot and cold discomfort; titanium mesh metal material, which affects the patient to accept the postoperative CT, magnetic resonance examination; can not do the fine and complex shaping. Another important point is that the titanium mesh is not very hard, not strong enough, if the external force again, it is easy to cause the titanium mesh to collapse and deformation, and may even hurt the brain tissue, very dangerous. Is peek cranial repair strong? Is it better than titanium mesh? Yes, overall PEEK is better than titanium mesh and much stronger than titanium mesh. There was a patient who had a titanium mesh repair that was hit by an external force, causing the mesh to collapse and compress the brain tissue, causing a series of uncomfortable symptoms, and visible scalp depression, affecting aesthetics. The patient came to our clinic after seeking medical treatment in many hospitals, and our team performed the titanium mesh removal and PEEK insertion surgery for him, which achieved satisfactory results. PEEK material is a new type of special polymer material, the name of the chemical name is polyether ether ketone, its texture is very hard, low density, high strength, good protective properties. Moreover, PEEK material has excellent performance in all aspects, such as tissue compatibility, elasticity, heat conduction, hardness, stability, and radiation transmittance, etc., which is comparable to the performance of autologous skull, and it can effectively avoid various problems that may arise from titanium mesh, and it has become a new trend of craniofacial repair materials. Our team not only uses this new material extensively, but also continuously improves and upgrades the technology and optimizes the design of the material, and introduces the concept of cosmetic plastic surgery, so as to carry out PEEK cranial bone repair and reconstructive surgery in a comprehensive way, and achieve the organic unity of anatomical integrity, perfect function, and beautiful appearance, which has been widely acclaimed.
