Epley's Manoeuvre: A Single Line Treatment for Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo.

Benign Paroxysmal Positional Vertigo (BPPV) is the commonest cause of peripheral vertigo. Displaced free floating otoconia in the semicircular canals are responsible for brief attacks of vertigo and nystagmus. Epley's manoeuvre relocates these particles into the utricle. Here we studied the efficacy of Epley's manoeuvre in posterior semicircular canal BPPV without labyrinthine sedatives. 120 patients presented with positional vertigo were included in the study based on positive Dix- hallpike test from August 2018 to July 2019. These patients were treated with only the Epley's manoeuvre and followed up for 6 months. Patients who were previously on labyrinthine sedatives were advised to stop them and treated with only the Epley's manoeuvre. In our study of 120 patients, mean age was 43.5 yrs. Females (52.5%) were commonly affected. Left side posterior semicircular involvement was more than the right side. Epley's manoeuvre had 90% efficacy at 1 week and 100% efficacy at 4 week. Duration of vertigo had significant association ( < 0.01) with the number of sessions required. There was significant improvement in the duration of vertigo attack ( < 0.0001) and frequency of attack ( < 0.0001) before and after the manoeuvre. Epley's manoeuvre lead to significant ( < 0.001) improvement in the quality of life of affected patients measured by DHI scoring. In our 6 months follow up, 10 recurrences occurred having significant ( < 0.01) association with the duration of vertigo attack. Only Epley's manoeuvre without any labyrinthine sedatives is an effective treatment for posterior semicircular canal BPPV patients. It also improves the quality of life of affected patients.
