Conditions of clinical recovery from partial facial palsy caused by injury to a branch of the facial nerve.
This study was conducted to elucidate the pattern of clinical recovery from partial facial palsy caused by injury to a branch of the facial nerve in rabbits. In the experiment, the state of recovery from palsy was investigated by observing the movement of the m. orbicularis oris of the rabbit at the time of food intake, as well as by observing the evoked wave and muscle contraction caused by nerve stimulation, and the muscle contraction caused by muscle stimulation. Recovery from peripheral facial nerve palsy is complete within 1 month after nerve impairment if over half of the nerve fibers of the impaired nerve are maintained intact without degeneration.
