- Abstract
- Backgrounds: Although various therapeutic maneuvers have been proposed, it is still unclear which maneuver is better to treat apogeotropic horizontal canal benign paroxysmal positional vertigo (HC-BPPV).
Objectives: This study aimed to assess the therapeutic efficacy of the cupulolith repositioning maneuver (CuRM) in apogeotropic HC-BPPV in comparison with the therapeutic head-shaking maneuver and modified Lempert maneuver.
Materials and Method: This is double-blind randomized prospective study. Forty-nine consecutive patients diagnosed with apogeotropic HC-BPPV were allocated randomly to CuRM (n = 18), therapeutic head-shaking (n = 16), or modified Lempert maneuver (n = 15). The presence of nystagmus and vertigo on positional testing were evaluated at 30 min, on 1 day, and 1 week after treatment.
Results: There were no significant differences in any clinical characteristics between the three groups at randomization. After a single trial of therapeutic maneuvers on the initial visit day, the CuRM (38.9%) and therapeutic head shaking maneuver (12.5%) did not show differences compared to modified Lempert maneuver (33.3%). The therapeutic effects on the 2nd day and at 1 week after treatment also did not differ between the three groups.
Conclusions: Although the CuRM is theoretically considered to be a better therapeutic method, the therapeutic efficacy of CuRM was not statistically different compared to the other two maneuvers.
