Abstract
During three years from 1982 to 1985, sixty six patients （sixty Bell's palsy and six Ramsay Hunt syndrome） received hyperbaric oxygen therapy （OHP）.
Among fifty four Bell's palsy visted Kure National Hospital within two weeks after onset, forty five showed complete recovery （83%）, seven cases were fairly good recovery and two showed poor recovery.
Twenty seven Bell's palsy were classified into three types by EMG and evoked EMG. In Type I （neurapraxia）, all patients recovered completely within thirty days. In Type II （incomplete denervation）, eleven out of fourteen showed complete recovery, but recoverying period prolonged.
OHP is well indicated for peripheral facial palsy and can reduce the period to get relief.
