Pm. Santos et al., DIURETIC AND DIET EFFECT ON MENIERES-DISEASE EVALUATED BY THE 1985 COMMITTEE ON HEARING AND EQUILIBRIUM GUIDELINES, Otolaryngology and head and neck surgery, 109(4), 1993, pp. 680-689
Fifty-four patients, diagnosed with Meniere's disease and treated with
diuretics and a low-salt diet, were evaluated retrospectively with th
e 1985 AAO/HNS Committee on Hearing and Equilibrium (CHE) guidelines f
or vertigo and hearing changes. The patient data base was also evaluat
ed with other methods that helped determine the effectiveness of the 1
985 AAO/HNS CHE guidelines. After 24 months of therapy, vertigo contro
l was complete or substantial in 79% of the patients, limited or insig
nificant in 19%, and worse in 2% as evaluated by the CHE 1985 guidelin
es. Hearing improved in 35% of the patients, was unchanged in 29%, was
worse in 22%, and could not be classified by CHE guidelines in 14%. H
eating was also evaluated by comparison of individual thresholds befor
e medical therapy, and at 22 and 74 months after the start of medical
therapy. We found a stabilization of low- and mid-threshold frequencie
s, with an average rate of hearing loss approximating 0 dB/yr with 74
months of followup. The results of this preliminary study suggest that
diuretics and a low-salt diet may decrease the natural progression of
sensorineural hearing loss in patients with Meniere's disease. Compar
ed with other methods of data analysis, the 1985 CHE guidelines lacked
sensitivity to evaluate the hearing changes observed.
