[Hypacusis in acquired hypothyroidism (author's transl)].
We examined 56 patients with latent or clinically manifest hypothyroidism and 18 patients with acute athyreosis as a control group. We were especially interested in the localization and extent of hearing abnormalities. 45% of the patients with chronic hypothyroidism showed a hearing loss. Of these, two patients had a pure conductive loss, seven a combined hearing loss and 16 a sensori-neural hearing loss. We demonstrated hair cell damage in 13 of the patients with chronic hypothyroidism. The hearing loss was mild to moderate in over 90% of the cases. Although several patients had a basocochlear hearing loss, no characteristic audiogram was found. There was a correlation between the conductive loss and the severity of the hypothyroidism. 50% of the patients showed a significant improvement in hearing after substitution therapy. The results of our examinations are discussed in detail.
