The long-term follow-up of 61 horizontal canal BPPV after Gufoni and Barbecue maneuver: a prospective study.

Horizontal canal BPPV (HC-BPPV) has a higher recurrence rate than PC-BPPV. Which maneuver is better for its prognosis is still uncertain. To compare the long-term recurrence rate after Gufoni and Barbecue maneuver. We prospectively collected 61 cases of HC-BPPV which were initially diagnosed in our hospital from the first episode, and had already ruled out other diseases. Roll them into Gufoni group and Barbecue group alternatively. After the maneuver, we followed them up until December 2016. Mean follow-up time was 49.25 months. The recurrence rate is 18.0% in the first year, 14.8% after the first year, and 31.1% overall. There is no statistically significant difference between Gufoni group and Barbecue group ( > .05). Age is statistically significant as a risk factor of recurrence (<.05). Barbecue maneuver is as good as Gufoni maneuver. The recurrence rate is only related to age. We suggest the disease relapsed within the 1st year as recurrence rather than a new disease.
