Cranial repair surgery is a routine neurosurgical procedure that has evolved over decades of history and has now become well established. The main purpose of the surgery is to repair the defective skull caused by debridement flap decompression and craniotomy with repair material. Generally, 2-3 months after the skull defect is the optimal time for repair, and through cranial repair, the defective area can be covered, and cosmetic effect can also be achieved to improve the quality of life of the patient. The exact duration of cranial repair surgery depends on the strength of the hospital chosen, the experience of the specialist and the type of repair surgery, and can usually be completed in 1-2 hours. At present, according to the surgical implant materials and surgical methods, clinically there are mainly traditional titanium mesh cranial bone repair and new polyether ether ketone peek material cranial bone repair plastic surgery; traditional titanium mesh cranial bone repair, because of the implantation of titanium mesh metal material, so there are still some problems, for example, the patient often occurs after the operation infection, rejection, deformation and collapse and so on, and in addition in the surgical methods of the traditional titanium mesh cranial bone repair using In addition, the traditional titanium mesh cranial repair uses the covering type repair method, which is very easy to lead to abrasion of the scalp, resulting in the titanium mesh exposed and so on. Polyetheretherketone peek material cranial bone repair plastic surgery, early years several years ago in Europe and the United States have begun to use, so far, there have been more than ten years of clinical experience summarized, can be very good to avoid titanium mesh cranial bone repair all kinds of problems. Polyether ether ketone peek material cranial bone repair plastic surgery using polyether ether ketone peek as a cranial bone repair implant material, this material is in full compliance with the national YY/T0660-2008 surgical implant industry standards, can effectively avoid the traditional titanium metal caused by allergy rejection and other problems; In addition, the polyether ether ketone peek material cranial bone repair plastic surgery in the surgical use of embedded repair, smooth In addition, the neurosurgery department of the Yellow River Center Hospital, after years of clinical summarization, adopts unique material thickness and mesh aperture design in three-dimensional design as well as unique intraoperative tissue separation and reset technology, which can increase the blood flow, effectively avoid temporal muscle atrophy, and ensure the activity of the tissues, which can effectively ensure the overall beauty of the postoperative appearance.
