Nine, hyperbaric oxygen treatment of peripheral facial nerve palsy and subluxation 1, peripheral facial nerve palsy: facial nerve palsy is a common disease mainly characterized by motor disorders of facial expression muscles, the pathogenesis of which is still inconclusive. The treatment of hyperbaric oxygen can reduce the hypoxic state of tissue cells, which is conducive to reducing neuroedema, increasing the regeneration of nerve axons and fibers, thus promoting the recovery of nerve function, together with glucocorticoids and antiviral, neurotrophic drug treatment, can achieve good results. 2.Subhealth state: a critical state.
