PURPOSE: Benign paroxysmal positional vertigo (BPPV) may be found in patients complaining of hearing disorders. The aim of our investigation was to describe audiological findings in BPPV patients, focusing on subjects with asymmetric hearing loss (AHL), to better understand whether otoconial displacement may occur preferentially in the worst hearing ear.
METHODS: A prospective study was performed on 112 BPPV patients. We divided the sample into subjects who suffered from AHL (G1) and patients with did not (G2). Data regarding vestibular symptoms, tinnitus, migraine, antivertigo drug therapy, and vascular risk factors were collected.
RESULTS: Out of 30 AHL subjects, 83.33% of them were affected by sensorineural hearing loss (SNHL) in at least one ear, with a significant difference in the distribution of hearing loss type between groups (p = 0.0006). In 70% of cases, the ear affected by BPPV was the one with the worst hearing threshold (p = 0.02); threshold asymmetry predicted BPPV in the worst hearing ear (p = 0.03). The predictability depended neither on the hearing threshold gap between ears nor the severity of the hearing threshold in the worst ear (p > 0.05). No differences in vascular risk factors between groups were observed (p > 0.05). We evidenced a moderate correlation between age and hearing threshold (ρ = 0.43). Age did not result a predictive factor for residual dizziness or BPPV in the worst ear (p > 0.05).
CONCLUSIONS: Our study supports the likelihood of an otoconial displacement in the worse hearing ear in BPPV patients. Clinicians should start testing the worst hearing ear when managing AHL patients with suspected BPPV.
