How long does it take to have cranial repair surgery? Many patients with cranial defects often ask about the duration of the surgery when they undergo cranial repair surgery. The duration of this repair is also determined by the area of the defect in the patient’s skull and depends on a number of factors, which are described in detail next. The human body has a large skeletal system, each piece of bone has its own role to play an important role. The skull is located above the spine and plays an important role. The skull protects the brain from external aggression, maintains a stable and normal intracranial environment, ensures normal circulation of cerebrospinal fluid and normal operation of intracranial life activities, and its role cannot be underestimated, but the hard skull may also be defective for some reason. If the skull is defective, it may lead to a series of neurological dysfunction, triggering cranial defect syndrome, the specific performance may have headache, dizziness, nausea, limb muscle weakness, fear of cold, fear of vibration, inattentiveness and other psychiatric symptoms, etc., in addition to cranial defects may be due to severe cerebral edema, dura mater of the brain tissue and cranial defects at the formation of myxomatous bulging, and embedded in the edge of the bone, resulting in a series of neuronal localization. Ischemic necrosis causes a series of neurological localization symptoms and signs. Therefore, after the cranial defect, cranial bone repair should be carried out in time. Good cranial bone repair material can achieve better repair effect. At present, the clinical introduction of new polyether ether ketone material, also known as PEEK material, which is very good in strength, elasticity, thermal insulation, plasticity, histocompatibility and other aspects of the performance is very good, and does not affect the postoperative CT MRI and other medical examinations, it is a very ideal craniofacial repair material. How long does it take to perform cranial bone repair surgery? Cranial repair surgery takes about 1 to 2 hours, while the timing of the cranial repair is also important. For patients with open comminuted skull fracture with relatively clean wound and no cranial hypertension, one-stage cranioplasty is recommended; while for patients with severe closed craniocerebral trauma and giant skull defect caused by cranial hypertension with decompression of the desmoid bone flap, the better time is about three to six months. I hope the above introduction will be helpful to you.
