What is the process of cranial bone repair? The occurrence of cranial defect affects the aesthetic appearance of the skull; in addition, the soft tissues inside the skull lack the protection of the hard shell and may be easily damaged by external forces; secondly, the instability of the intracranial pressure caused by cranial defect may also affect the normal operation of the vital activities inside the skull. Cranial defects may lead to frequent headaches and dizziness, in addition to the patient’s fear of pulsation, expansion and collapse of the defective area, as well as fear of sunlight, vibration and even loud noises. It may also cause lack of concentration and memory loss, and some patients show depression, fatigue, reticence and low self-esteem. Therefore, it is necessary to perform skull repair surgery in time after skull defect. What is the procedure of skull repair? The skull repair procedure is performed by first anesthetizing and disinfecting the skull, then cutting the scalp, exposing the bone window, taking the preoperative three-dimensional shaped polyetheretherketone PEEK repair piece, adjusting and fixing it according to the shape of the patient’s skull defect, suturing the scalp, and completing the procedure. It is necessary to emphasize that not only is it important to standardize the correct detailed steps of cranial repair surgery, but also the cranial repair material is important. Clinically, the current repair material used for cranial repair is peek cranial repair. peek material can be shaped in three dimensions according to the patient’s cranial data and highly restore the anatomical structure of the cranium, in addition, its performance in elasticity, hardness, heat insulation, stability and other aspects is basically the same as the autologous cranial bone, there is no rejection, and it will not interfere with CT, MRI and other examinations, so it has become the new favorite in the cranial repair world.
