Abstract
Treatment of vascular disorder with cytochrome C has been reported in the fields of neurosurgery and internal medicine. But it is unknown wheather the drug might be effective to otological disease with deafness and/or vestibular symptom.
The authors would describe three cases, to which intravenous injections of cytochrome C were effective. The first one was sudden deafness, the second one progressive deafness and the last one head injury.
Definite improvement of hearing was achieved in all cases after injections. The case of head injury had both atypical alternating spontaneous nystagmus and unilateral optokinetic nystagmus inversion. But both symptoms have disappeared by injections. The cause of improvement of the symptoms is still unknown.
