Hearing recovery and vestibular symptoms in patients with sudden deafness and profound hearing loss

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.
