To evaluate whether a repeated canalith repositioning procedure (CRP) influences the residual symptoms and the rate of recurrence of benign paroxysmal positional vertigo (BPPV) in patients with post-CRP dizziness. Materials and methods: In this retrospective study, we analyzed 292 patients at the referral center for ENT diseases with a first episode of BPPV treated with a single CRP following clinical practice guidelines. In 178 patients (67.9%) who presented dizziness after BPPV recovery at the follow-up visit, 94 patients underwent CRP (treated group) and 84 did not (non-treated group). A subjective evaluation of vertigo was made by way of a questionnaire. The rates of recurrence of BPPV and residual dizziness were statistically compared between the treated and the non-treated groups; survival analysis was carried out as well. Results: In an observational period ranging from 1 to 6 years, BPPV recurred in 122 subjects (46.6%) of the investigated population. Among the patients with residual dizziness, the difference in rate of recurrence of BPPV between the treated group and the non-treated group was not statistically significant (p = 0.84). The treated group presented a significantly higher rate of recovery from dizziness compared to the non-treated group (p < 0.001). Conclusions: A repeated CRP in patients with post-CRP dizziness increased the rate of recovery from dizziness but had no influence on BBPV recurrence. evaluate whether a repeated canalith repositioning procedure (CRP) influences the residual symptoms and the rate of recurrence of benign paroxysmal positional vertigo (BPPV) in patients with post-CRP dizziness.
