Cranial repair is a relatively old procedure that has been developed over thousands of years of human history. Over time, cranial repair has become a well-established routine procedure in neurosurgery. Of course, as the technology continues to evolve, so do the materials used in cranial repair, which are more advanced and better adapted to the human cranial environment. Early medical workers used to use cranial bone repair materials such as calcium phosphate bone cement, plexiglass, silica gel, hydroxyapatite and so on, but the effect of these materials are not ideal, because of various problems and no longer used. Currently, titanium alloy is the most widely used cranial bone repair material in clinical practice. When using titanium alloy for cranial bone repair, the titanium alloy mesh is covered on the bone window and fixed with titanium nails, which is generally unlikely to fall off. However, although titanium alloys have advanced properties compared to more traditional materials, they also have many drawbacks and shortcomings. For example, titanium alloy material hardness is not enough, there may be deformation by external forces; titanium alloy metal material insulation is not good, the patient will be very sensitive to the external hot and cold environment after the operation, resulting in a lot of discomfort; titanium alloy covered repair of the edge of the scalp may be abrasive; after the operation may also occur in the rejection of infections, and even lead to scalp breakage, the material is exposed, and so on. Therefore, the use of titanium alloy for cranial bone repair is not recommended at present. Currently, a more advanced material for cranial repair is the polyetheretherketone peek material. Our team carried out peek cranial repair plastic surgery for him, restored a complete and beautiful skull shape for him, and also removed a piece of his heart disease, to achieve anatomical integrity, functional perfection, beautiful appearance of the good results.
