Life because of various reasons or accidents, resulting in the need for cranial repair, cranial repair application is cranial repair, is the most common neurosurgery surgery, surgery outside the brain, generally there is little risk, after the completion of the surgery, the appearance of the appearance of no difference with the normal person, and so on, when the hair grows out will be basically invisible, so what material should be chosen to do the repair surgery is better? Below I will introduce to you. Titanium mesh: 1, titanium mesh is a higher hardness and lighter weight material in the metal, which is more suitable for cranial bone repair material than other metals. 2.Titanium mesh, as the most widely used material, has good biocompatibility and chemical stability. 3.Titanium mesh is a non-corrosive metal, resistant to body secretions and non-toxic. Titanium mesh can be shaped by computer, which can restore the head better. 4, titanium mesh postoperative infection rate is lower than the previous plexiglass, bone cement, etc., the difficulty and risk of surgery will also be lower. However, titanium mesh also has a disadvantage, metal material insulation temperature ability is poor, conductive heat will have a greater scalp stimulation. PEEK material: the most ideal repair material in recent years, almost all the advantages of cranial bone repair materials, biocompatibility, chemical stability, insulation, thermal insulation, hardness, elasticity are also better than titanium mesh. Peek is used as a repair material for cranial bone repair. Through clinical practice, it is found that PEEK material has low density, is not sensitive to temperature, has high tissue stability, and can be sterilized under high temperature or radiation without deformation. Through a large amount of clinical feedback, it was found that the PEEK material is radiopaque and does not affect the results of CT and MRI. The surgery not only achieves the repair of individual skulls, but also makes great efforts in cosmetic surgery. Scientific analysis and study of each patient’s specific situation and signs are carried out to optimize the design of the repair material and to formulate personalized and meticulous surgical plans for cranial repair and cosmetic surgery, so as to achieve the unity of aesthetics, anatomical integrity and functional perfection.
