Abstract
Objectives: Vertigo is considered a poor prognostic factor in patients with sudden sensorineural hearing loss (SSNHL). Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo and may accompany SSNHL. However, whether BPPV is a poor prognostic factor remains controversial. We identified features of prognostic utility in patients with both SSNHL and BPPV.Methods: We retrospectively evaluated data on all patients diagnosed with SSNHL at Keimyung University Dongsan Medical Center between January 2011 and December 2015. We reviewed medical records, the results of vestibular function testing, and audiographic data.Results: Of the 524 idiopathic SSNHL patients, 20 (3.8%) were also diagnosed with unilateral BPPV. The average pure tone average (PTA) of those with both SSNHL and BPPV was higher than that of those without BPPV. Of the 471 patients with SSNHL only, 143 (30%) exhibited complete recovery. Of the 33 SSNHL patients with vertigo, 3 (9%) exhibited complete recovery, but only 3 (15%) of those with both SSNHL and BPPV exhibited complete recovery. Of the 20 patients with both SSNHL and BPPV, 15 had ipsilateral BPPV and 5 contralateral BPPV.Conclusions: Patients with BPPV had a higher average initial PTA score and poorer hearing recovery after treatment, than patients with SSNHL alone. Patients with contralateral BPPV had a somewhat better prognosis than those with ipsilateral BPPV, but statistical significance was not attained.
