Abstract：Objective To compare the modified Li's repositioning maneuver and Semont repositioning maneuver in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV). Methods From October 2015 to April 2016,80 patients with PC-BPPV were divided randomly to be treated with modified Li's repositioning maneuver or Semont repositioning maneuver. Patients were followed up for 3 months and treatment outcomes were compared be-tween the two maneuvers. Results In the 40 patients treated with modified Li's repositioning maneuver, total improve-ment rate was 92.5% (37/40) and 87.5% (35/40) at one week and 3 months respectively, with recurrences in 2 cases (5%);while in the 40 patients receiving Semont repositioning maneuver, the total improvement rate was 90%(36/40) and 85% (34/40) at one week and 3 months respectively, with recurrences in 3 cases (7.5%) (P>0.05). Conclusions The modified Li's repositioning maneuver is an effective and simple treatment method for patients with PC-BPPV, with comparable efficacy as the Semont repositioning maneuver. It can be adopted in clinical practice.
