The skull is a hard and indispensable bone in the human body, which plays a pivotal role in the normal operation and health of all life activities. Once a skull defect occurs, it is obvious that the patient’s appearance will be seriously damaged, some will be collapsed, some will be bulging, either way, it will make the patient become less confident, resulting in a deep sense of inferiority; in addition, without the protection of the skull, the brain tissue is easy to be damaged, prone to cause cerebrospinal fluid circulation abnormalities, blood supply disorders and other problems. Craniovertebral repair is a routine surgery for neurosurgery to remedy cranial defects. The main purpose of the surgery is to replace the defective cranial bone with a material similar to human autologous cranial bone, repair the bone window of the defective part, realize the integrity of the cranial bone once again, restore the airtightness of the cranial cavity, maintain the stability of physiological intracranial pressure, and alleviate the occurrence of the craniovertebral defect syndrome; through the repair of the defects, it achieves the symmetry of the left and right side of the head, and the natural and beautiful appearance, and improves the patient’s cerebral spinal fluid circulation abnormalities and blood supply disorders. The repair of the defect can achieve symmetry of the head shape and improve the patient’s inner self-confidence. In the neurosurgery guidelines, generally 2-3 months after the debridement surgery, the defect diameter is greater than 3 cm or more, that is, it meets the surgical indications, and the patient needs to be repaired in a timely manner. Although cranial bone repair belongs to the routine neurosurgery, it is also a large craniotomy, and it is recommended to go to a large public hospital for surgery. It is reported that at present, many hospitals generally carry out titanium mesh cranial bone repair, selected titanium mesh as the cranial bone implantation material, but due to the implantation of titanium as a metal material and the use of cover-type repair, there are many postoperative complications such as the rate of rejection and infection, wear and tear of the skin material exposed. In view of this, after years of clinical exploration and summarization, our hospital upgraded and improved the original cranial bone repair technology to form a mature technology – peek material cranial bone repair plastic surgery, it is a new type of peek as a cranial bone repair implant material, greatly reducing the rate of postoperative rejection rate, the infection rate; and at the same time, using the embedded repair method, effectively avoiding the traditional titanium mesh cover repair material. At the same time, it adopts embedded repair method, which effectively avoids the phenomena of skin wear and ulceration and material exposure caused by the traditional titanium mesh covering repair; in addition, it innovatively introduces the concept of plastic surgery, combines the unique design of mesh aperture and the unique tissue separation and reset technology during the operation, which effectively avoids the temporal muscle atrophy and guarantees the activity of various tissues to ensure symmetry of the head after the operation and to achieve the purpose of a natural and beautiful appearance.
