The main purpose of the surgery is to replace the defective skull bone with a material similar to human autologous skull bone, to repair the bone window of the defective area, to achieve the integrity of the skull again, to restore the cranial cavity confinement, to maintain the stability of physiological intracranial pressure, to reduce the occurrence of skull defect syndrome; through the defect repair, to achieve the symmetry of the head shape Through the defect repair, the head shape is symmetrical, the appearance is natural and beautiful, and the patient’s inner confidence is improved. In the neurosurgical guidelines, generally 2-3 months after the debridement surgery, the diameter of the defect is greater than 3 cm, which is in line with the indications for surgery, and the patient needs to be repaired in time. Of course, cranial repair needs to choose a good repair material, at present, polyetheretherketone peek material is a new trend of current cranial repair material. It is the preferred repair material for patients with cranial defects. Next, we will give you a detailed explanation of the advantages and costs of cranial peek cranial repair. PEEK material is a new type of special polymer material, its properties are very close to the human autologous cranial bone, in clinical applications with excellent results. peek material has very good histocompatibility, basically will not produce rejection; PEEK material is based on the patient’s cranial CT data for three-dimensional shaping, highly restore the physiological structure of the skull; PEEK cranial is embedded repair, repair good cranial appearance smooth, will not produce The skull is smooth in appearance and does not produce cutting injuries like those caused by titanium mesh-covered repair; PEEK material has good radiation transmission and does not affect various medical examinations after surgery; in addition, the performance of PEEK material in terms of elasticity, strength, thermal insulation, stability, etc. is comparable to that of human skull and is a very ideal material for skull repair. For the price of peek material, there are different rates, calculated according to the size of the bone window, of course, can also enjoy the health insurance policy.
