ABSTRACT
OBJECTIVES:
To review the clinical features of benign paroxysmal positional vertigo (BPPV) secondary to sudden sensorineural hearing loss (SNHL) and to analyze the correlation between canal paresis and the effectiveness of canalith repositioning procedures (CRPs) for the treatment.DESIGN:
Study case series with chart review.SETTING:
Academic university hospital. PATIENTS We retrospectively reviewed 277 patients with BPPV. For sudden SNHL with a recent vertigo, patients underwent electronystagmography and bithermal caloric tests. We investigated the clinical characteristics including causes, type of involved semicircular canal, frequency of CRPs, treatment results, and canal paresis (CP).INTERVENTIONS:
The diagnosis of BPPV accompanied by same-sided sudden SNHL was based on the results of head roll and Dix-Hallpike tests.RESULTS:
Of 277 patients with BPPV, 24 (8.7%) had sudden SNHL. Multiple-canal involvement most commonly developed in post-sudden SNHL BPPV (pâ<â0.01). Patients with post-sudden SNHL BPPV received a greater number of CRPs (2.95) than those with idiopathic BPPV (1.58) (pâ=â0.043). In patients with post-sudden SNHL BPPV, the average number of CRPs was 3.31 in the presence of CP and 2.1 sessions in the absence of CP (pâ=â0.030); the CP value was correlated with the frequency of CRPs (pâ=â0.020).CONCLUSIONS:
In post-sudden SNHL BPPV, the worse the canal paresis becomes, the greater the number of CRPs will be needed for treatment; the simultaneous involvement of the posterior semicircular canal and horizontal semicircular canal is most common.
