흥역항체역가가 증가된 양측성 감각신경성 난청 1례

Infectious diseases remain a primary cause of hearing impairment despite continuing development and introduction of new antimicrobial drugs. Viral infections implicated in hearing loss include rubella, measles, mumps, herpes zoster, cytomegalovirus and influenza. Permanent unilateral and bilateral hearing loss is a known but uncommon complication of measles, mumps, and rubella in adults as well as in children. Severe hearing loss has been reported as a complication of the measles- mumps-rubella vaccination in children, usually in association with encephalitis.

We described a case where delayed bilateral sensorineural hearing loss following a asymptomatic measles infection without specific rash, fever, and a history of use of ototoxic drugs. Audiogram revealed 40V60dB sensorineural hearing loss. The cause of hearing loss is unknown, but measles remains one possibility because elevated IgG antibody titer is that for measles only on serologic test. A therapeutic trial of steroids did not improve the patient’s hearing.

We considered measles virus to be one of the possible pathogens causing profound and irreversible hearing loss, including sensorineural hearing loss.

This report emphasizes the risk of permanent hearing loss as a complication of measles infection and discusses strategies for early diagnosis and prevention.
