Two cases with mumps deafness of sudden onset are reported.
Case 1: A man aged 25 was referred to the ENT clinic of the National Defense Medical College by an otolaryngologist because the patient complained of hearing impairment and tinnitus of the left ear and vertiginous attacks in the course of mumps. The audiogram showed a left profound hearing loss. Caloric tests of vestibular function indicated the presence of a left vestibular paralysis. A diagnosis of profound sensori-neural deafness and vestibular paralysis by mumps infection was made. Steroid hormone therapy was applied for approximately 2 weeks. However, no recovery has been noted.
Case 2: A woman aged 43 presented at the ENT clinic with complaints of hearing impairment, tinnitus of the left ear and dizziness. They have been noted since she had suffered from mumps. The audiogram showed a left profound hearing loss. Caloric tests revealed an absent responsiveness of the affected ear. A diagnosis was made of profound sensori-neural deafness and vestibular paralysis due to mumps. Hearing and caloric impairments did not return to normal by administration of high doses of vitamin B complex.
