Abstract

PURPOSE:

To compare the audiological results of elderly subjects based on the classifications according to the criteria of Davis and Silverman and of the recommendation 02/1 of the Bureau Internacional d'Audiophonologie (BIAP).

METHODS:

The records of 140 elderly subjects, 79 female and 61 male, with average age of 69.75 years, were analyzed. Data regarding their clinical history and the results from pure tone audiometry were gathered, and occurrences were classified according to: type of hearing loss; audiometric curve; affected ear; and degree of hearing loss, according to the purposes of Davis and Silverman and the recommendation 02/1 of the BIAP. Data were statistically analyzed.

RESULTS:

The most frequent audiological complaints were tinnitus, itchiness, dizziness and otalgia. There were reports of noise exposition. Regarding the audiometric configuration, 105 ears showed descending curve, 88 had horizontal curve, and 24 presented normal curve configuration bilaterally. Fifty seven of the individuals with hearing loss were male and 59 were female, corresponding to 93.44% of the total number of male subjects and 74.68% of the female subjects. Mild and moderate sensorineural hearing losses were predominant, with little prevalence difference according to each of the classifications. The degree of hearing loss was worse and there were lesser cases of normal hearing when the BIAP classification was considered. The classification proposed by Davis and Silverman identified 99 cases of normal hearing, while the BIAP classification identified only 66 cases.

CONCLUSION:

The classification criteria suggested by Davis and Silverman and by the BIAP recommendation presented similar results. However, the BIAP criteria are more sensible to detect hearing loss in elderly subjects.
