The skull is one of the important bones in the human body and it plays a vital role in the human skeleton. Firstly, the presence of skull bone also plays a role in beautifying the appearance; secondly brain tissue and cranial surface organs need this hard shell for protection; in addition the skull maintains normal and stable intracranial pressure, which is necessary for all life activities in the skull; therefore, if there is a defect in the skull, the danger is self-evident and certain measures should be taken to remedy it in time, at which point skull repair surgery shines in the field of neurosurgery. There is currently a consensus in neurosurgery that a cranial defect can be repaired intact in a hospital three months after it has occurred. While the conditions for cranial repair are met, the materials used for the surgery are also very important. The ideal implant material not only matches the defect area perfectly, but also reduces complications such as rejection infection. Metal titanium mesh obviously cannot achieve the ideal result due to the disadvantages of rapid thermal conductivity, collapse and deformation under external force, and large irritation of the scalp for overlay repair. The new peek material is excellent in histocompatibility, pressure resistance, and perfect shaping, and is embedded in the human body when placed, which is less irritating to the scalp and effectively avoids the various problems of titanium mesh. Therefore, peek cranial repair surgery has become the best choice for patients with skull defects. Our team innovatively proposes to incorporate the concept of aesthetic plastic surgery to ensure the unity of aesthetic appearance, anatomical integrity and functional perfection after surgery. Although skull repair surgery is a routine procedure, there are some things that should be paid attention to after surgery to ensure a faster recovery. First of all, patients should pay attention to avoid doing strenuous exercise after stitch removal to prevent external force from hitting the repaired skull part; after surgery, patients are recommended to rest for six months, eat more food with high protein and vitamin containing phospholipids, and do regular review.
