The evolution of hearing
During the first years of the disease, the greatest degree of hearing
loss coincides with a higher prevalence of vertigo episodes (1), even
though these subsequently diminish or disappear while hearing loss
persists (21,22). In this regard, our results show that patients within
model number one, who suffer from vertigo episodes for a shorter time,
experience less hearing loss. This could be explained by the fact that,
experiencing episodes of vertigo for a shorter period of time is
associated with better preservation of hearing. However, model number
two presented greater mean hearing loss than those in model number
three, which is that in which there was a worse severity in the temporal
evolution of vertigo episodes.
