Cranial repair surgery has a thousand years of history, and with generations of medical people’s hard work, the technique of cranial repair has been very perfect. As a routine surgery of brain neurosurgery, as long as a doctor who has been engaged in brain neurosurgery for years, his attainment in cranial bone repair is certainly not low. Currently, a new polymer biomaterial is also used in the clinical application of cranial bone repair. The medical application of this material, called PEEK, has greatly compensated for the shortcomings of cranial prosthetics. Using PEEK material, the material itself also has excellent bionic properties, high thermal insulation, good stability, and high compressive strength, making it an excellent material for cranial bone repair in every way. For patients with cranial defects the question of how long to be awake after cranial bone repair has become a question for them all. It is also for the improvement of hospital technology and the optimization of materials, so that the care and recovery time of cranial bone repair surgery is greatly reduced. If the PEEK material is chosen and no other medical conditions exist, you can generally move freely three days after surgery. Following the doctor’s instructions for rehabilitation for one week, you can be discharged from the hospital for recuperation. Following the doctor’s instructions for more rest and a light diet, a full recovery can be achieved in half a month to a month’s time.
