Vagus nerve injury is divided into etiologic treatment and symptomatic treatment. First, firearm injuries, mostly due to high-speed projectile injury, nerve injury is extensive, the wounds are heavily contaminated, inhibit wound infection. Initial treatment principle, the wound should do a thorough debridement, rather than suture the nerve. Do not do resection of the nerve injury part, nor do free disconnection, to prevent the spread of contamination. Second, skull base fracture, itself does not need special treatment, focusing on prevention of infection and reasonable use of antibiotics. Third, intraoperative enhancement of nerve protection, the implementation of skull base surgery, the application of microsurgical techniques, carefully protect the vagus nerve. It is very important to protect the glossopharyngeal nerve from irreversible damage. Fourth, central nervous system inflammation should be anti-inflammatory, anti-inflammatory before it is too late, and the course of the disease should be sufficient. V. For tumors of the skull base, surgical treatment or stereotactic radiotherapy should be performed as appropriate. For tumors in the occipital foramen magnum area, the extracranial segment is mainly resected, and those with intracranial remnants should be treated with stereotactic radiotherapy. The medullary glioma belongs to limited exophytic feasible microsurgical resection, with stereotactic radiotherapy and chemotherapy. Symptomatic treatment: I. For patients with severe cough, a pasty semi-liquid diet should be carried out. For patients with high intracranial pressure, reduce the intracranial pressure. For patients with headache, nausea and vomiting, analgesic treatment is feasible.
