Lesion-side laterality was identified in 31 (40.8%) of the 76 patients
with ISSNHL and these patients had a lower hearing recovery rate
(P<0.05). Furthermore, patients with a lower initial hearing
threshold (dB), word recognition score, and lesion-side posterior
semicircular canal gain displayed poorer hearing recovery
(P<0.05). Initial hearing threshold and word recognition score
did not change significantly as the extent of the enhancement in the
labyrinth increased; however, the probability of being accompanied by
vertigo and the total score on the vestibular function tests did
increase (P<0.05).
