Short-Term Effect of Epley Maneuver as Treatment for Subjective Benign Paroxysmal Positional Vertigo.

Subjective Benign Paroxysmal Positional Vertigo (S-BPPV) is an atypical form of BPPV, its treatment is not well characterized and is not well known among otolaryngologists. The main aim of this study was to estimate the short-term efficacy of Epley maneuver as treatment for S-BPPV. This was a prospective study in a secondary care center. We included patients with unilateral S-BPPV demonstrated by negative nystagmus on Dix-Hallpike Maneuver (DHM) but with unilateral vestibular symptoms (dizziness or vertigo). Epley maneuver to the affected side was performed. Patients underwent Dizziness Handicap Inventory (DHI) and at 1-week follow-up, DHI and DHM were repeated. Outcome measures were resolution of symptoms during DHM and improvement of DHI scores. Patients were divided into resolved and unresolved groups according to the absence or presence of symptoms during the 1 week DHM. Wilcoxon-Mann-Whitney and Kruskal-Wallis tests were used, quantitative values were reported as mean and standard deviation. The results included thirteen participants, 12 females and 1 male, mean age 53.31 years (SD ± 15.71). Right ear was involved in 46.15% and left in 53.84%. A total of 46.15% patients (n = 6) had resolution of symptoms. DHI initial score for the resolved group was 34.66 ± 22 and for the unresolved group was 39.71 ± 19.61 (= 0.568). At 1-week evaluation scores were 19.66 ± 25.05 for the resolved group and 30.28 ± 21.42 for the unresolved group (= 0.252). DHI improvement was 15.00 ± 23.21 and 9.42 ± 10.17 for each group, respectively (= 0.943). We concluded the Epley maneuver is an effective short-term treatment for S-BPPV. Half of the patients would need further diagnostic tests.
