Short-term outcomes of Li's repositioning maneuver of different age groups patients of horizontal semicircular canal canalithiasis benign paroxysmal positional vertigo

Abstract

Objective:To analyse whether there is statistical difference between different age group short-term outcomes of horizontal semicircular canal canalithiasis benign paroxysmal positional vertigo (HC-BPPV) patients treated by Li's repositioning maneuver.Method:Since October 2009 to July 2017, we included 169 unilateral HC-BPPV patients treated by Li's repositioning maneuver. Then we recorded and analyse 3-day and 1-week outcomes.Result:Three-day efficacy rates of youth, middle aged, young elderly and elderly patients were 97.9%,93.9%,90.9% and 90.% (P=0.136), respectively. Rates of 1-week efficacy were 100.0%,98.5%,97.7%and 100.0% (P=0.799),respectively. There was no statistical difference.Conclusion:Treated by Li's repositioning maneuver,HC-BPPV patients of different age groups can both get good short-term outcomes without statistical difference.
