The skull is above the spine and is at the top of the human skeletal system, and the role of the skull is also very important. The skull is composed of 23 bones of different sizes and shapes, which are very delicately articulated and occluded together to form a complete and closed cranial cavity, which plays an important role in protecting and supporting the brain and the head and facial organs. Therefore, the cranium is very important for the health of human and the life of the whole organism. If a cranial defect occurs, then cranial repair should be performed in a timely manner. Cranial repair is a routine surgical procedure for repairing cranial defects caused by various reasons. Through cranial repair, a complete and closed cranial environment can be rebuilt to ensure the normal operation of intracranial cerebrospinal fluid circulation, blood circulation and neurological function, and to maintain the overall smooth health of the human body. Cranial bone repair is a routine surgery in neurosurgery, and the technology is very mature. The factor that has a great influence on the effect of cranial bone repair is what kind of repair material is used. Although this metal material is more advanced than other materials in the past, there are still some defects and shortcomings, and such problems have appeared in clinical use, such as postoperative infection and rejection, scalp exposure, collapse and deformation, affecting CT MRI, sensitivity to external heat and cold, etc. Therefore, titanium mesh material is not ideal. Therefore, titanium mesh material is not a very ideal material for repair. At present, there is a new polyetheretherketone peek material with more excellent performance, its properties are very close to the human autologous cranial bone, which can well overcome the above problems that may arise from titanium mesh. Polyetheretherketone peek material is excellent in biocompatibility, hardness, elasticity, heat insulation, radiolucency, shaping effect, etc. It can achieve good repair effect and is favored by patients with cranial defects and neurosurgeons. So what is the price of polyetheretherketone cranial repair? At present, our team is widely using this advanced polyether ether ketone peek material to repair the skull, and the team is constantly carrying out technical innovation and introducing the concept of cosmetic plastic surgery to carry out comprehensive peek skull repair plastic surgery, which can achieve good results of anatomical integrity, perfect function and beautiful appearance, and the cost is not high, which is well received and recognized by the majority of patients and their families.
