Audiometric data from 76 patients with unilateral sudden deafness and hearing loss of 80 dB or more were studied to statistically assess the relationship between vestibular findings (vertigo and/or dizziness, nystagmus, canal paresis) and hearing recovery in various frequency ranges. Hearing recovery in patients with vertigo and/or dizziness (V(+)) was much poorer than in patients without such findings (V(-)). Concerning hearing recovery in the high frequency range, a significant statistical difference was evident between the V(+) and V(-) group. There were no statistically significant differences in hearing recovery between patients with spontaneous nystagmus or canal paresis and those without.
