Cranial bone repair is a routine surgery in neurosurgery, which is a surgical procedure to repair cranial defects due to various reasons, with the aim of restoring the closed cranial cavity of the skull, restoring the normal and stable cranial cavity environment, and guaranteeing the normal operation of various neurological functions and life activities. Glass materials, bone cement, silicone and other materials are no longer used in clinical practice due to various defects. At present, most of the hospitals in the clinical more widely used cranial bone repair material is titanium mesh material, but this material also exists certain defects, such as postoperative infection and rejection phenomenon, hot and cold sensitivity reaction phenomenon, easy to deformation, affect the ct nuclear magnetic examination and so on. Now there is a more advanced material called polyether ether ketone peek material. Is peek skull bionic bone? Polyether ether ketone peek material is a new type of special polymer material with excellent performance, he is very good to overcome the titanium mesh material may produce a variety of problems, applied in the cranial bone repair can be achieved very excellent repair effect. peek material properties are very close to the person’s own cranial bone, in the hardness, elasticity, thermal insulation, tissue compatibility, shaping and so on, is very excellent! The material can also be customized to fit the shape of the patient’s skull in a three-dimensional fashion, which is highly restorative to the appearance of the skull. The neurosurgery team has widely used this advanced material for cranial bone repair surgery, which has achieved very good results in clinical practice, and has been well received and recognized by patients and their families. The neurosurgery department not only uses this advanced material, but also constantly carries out technical innovation and upgrading, optimizes the design of the material and adds the concept of cosmetic plastic surgery, so that the comprehensive peek cranial repair surgery can achieve the organic unity of aesthetic appearance, perfect function and structural integrity, and the effect is very outstanding.
