Аннотация
OBJECTIVE: Audiological data from a population based epidemiological investigation were studied on elderly persons. Specific diagnoses of otological and audiological disorders, which can result in hearing loss, were searched for.
DESIGN: A retrospective register study.
STUDY SAMPLE: Three age cohorts, 474 70- and 75-year olds ("younger"), and 252 85-year olds ("older"), were studied. Clinical pure tone and speech audiometry was used. Data from medical files were included.
RESULTS: Conductive hearing loss was diagnosed in 6.1% of the "younger" elderly persons, and in 10.3% of the "older" ones. Specific diagnoses (chronic otitis media and otosclerosis) were established in about half of the cases. Sensorineural hearing loss, other than age-related hearing loss and noise induced hearing loss, was diagnosed in 3.4 % and 5.2% respectively. Severely impaired speech recognition, possibly reflecting age-related auditory neuropathy, was found in 0.4% in the "younger" group, and in 10% in the "older" group. Bilateral functional deafness was present in 3.2% of the 85-year-old persons, but was not present in the 70-75-year group.
CONCLUSION: The incidence of probable age-related auditory neuropathy increases considerably from 70-75 to 85 years. There are marked differences between "younger" and "older" elderly persons regarding hearing loss that severely affects oral communication.
