Abstract
Objective:To compare the effectiveness of canalith repositioning procedure between BPPV secondary to sudden sensorineural hearing loss（SSNHL） group and idiopathic BPPV（i-BPPV） group. Methods:A retrospective study of patients with evidence of idiopathic BPPV or SSNHL with BPPV. All participants were identified and categorized by using the Dix-Hallpike test and roll test, and then followed by canalith repositioning procedures （CRPs）. The assessment of outcome was conducted at one-week post-CRPs. Results:Sixty-four BPPV patients secondary to sudden sensorineural hearing loss and 328 patients with idiopathic BPPV were included. The posterior canal is the most affected in both group. At one-week post-treatment, the effectiveness of CRPs in the BPPV with SSNHL group was significantly lower than that of the i-BPPV group （P<0.001）. Conclusion:The clinical characteristics of BPPV secondary to SSNHL were like those of i-BPPV, while BPPV secondary to SSNHL was associated with poorer outcomes than i-BPPV when treated by CRPs.
