In the current life, there are many people who suffer from cranial defects due to various reasons. For example, car accidents/traumatic brain injuries/debriding flap decompression surgery. Losing the protection of the skull makes the intracranial tissues susceptible to external injuries, and if infections and other conditions occur, they can also affect normal neurological function. One question that many patients worry about after cranial repair is, how long is the recovery period after cranial repair? This question is actually a bit redundant. Technically speaking, cranial repair surgery has a thousand-year history, and under generations of medical people, the current cranial repair technology has been very perfect. As a neurosurgery routine surgery, as long as the doctor is engaged in brain neurosurgery for many years, in the cranial bone repair art attainment is certainly not low. At present, a new polymer biomaterial is also used in the clinical application of cranial bone repair. This kind of medical application called PEEK material greatly makes up for the short board of cranial bone repair surgery materials. The use of PEEK material, completely traditional titanium mesh material of the hot and cold reaction sequelae, and the material itself is also very good bionic characteristics, high thermal insulation, good stability, compressive strength, in any respect, are excellent cranial bone repair materials. The refinement of the technology and optimization of the material allows the care and recovery time of cranial bone repair surgery to be greatly shortened. Generally speaking, if PEEK material is chosen, free movement is usually possible three days after surgery if no other medical conditions exist. After one week of rehabilitation according to the doctor’s instructions, you can be discharged from the hospital to recuperate. Follow the doctor’s instructions to rest more, eat a light diet, half a month to a month’s time to achieve the effect of full recovery.
