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).
