Recently there was hypothesis that relates the otolith dysfunction to the recurrence of benign paroxysmal positional vertigo (BPPV). Therefore in the present study, we assessed relationship between cervical vestibular evoked myogenic potential (cVEMP) and BPPV recurrence and raise the possibility of cVEMP as a recurrence indicator of BPPV. Methods: A retrospective review of patient from November 2009 to June 2014 was carried out. Ninety-four patients who suffered from BPPV were enrolled. Medical record review and telephone survey was done to check BPPV recurrence. Results: In medical record review, normal cVEMP group showed 18.9% recurrence rate and abnormal cVEMP group showed 25%. In telephone survey, normal cVEMP group showed 39.19% recurrence rate and abnormal cVEMP group showed 60%. There was no significant statistical difference. Conclusions: cVEMP abnormality was not a risk factor of BPPV recurrence. Further study with larger number of enrolled subjects is necessary.
