We used Frenzel to observe nystagmus to eliminate visual fixation. The nystagmus is a combination of torsional nystagmus with the upper pole of the eyes beating toward the lower ear combined with vertical nystagmus beating upward (toward the forehead) typically lasting <1 min. The diagnosis of PC-BPPV was performed using the diagnostic criteria established by the Bárány Society in 2015 ( 3), which included a history of recurrent transient positional vertigo and induced positional nystagmus by the Dix–Hallpike test. All patients underwent routine nervous system examination and laboratory examinations. Patients and Methods Patientsīetween October 2019 and October 2020, 155 consecutive patients with a diagnosis of unilateral PC-BPPV were recruited at the neurotology unit of our clinic. In this study, a modified Epley maneuver for self-treatment at home was introduced and its therapeutic efficacy evaluated and compared to the conventional Epley maneuver. Thus, the self-treatment approach is a desirable option for patients with PC-BPPV. PC-BPPV also has a high recurrence rate ( 6, 7) and frequent recurrences render patients with PC-BPPV dependent on costly and time-consuming medical care. In a retrospective study, 84% of patients obtained symptomatic control of PC-BPPV after three Epley maneuvers ( 5), which means repeated Epley maneuvers are required for some patients until PC-BPPV resolves completely. Treatment of PC-BPPV relies on a canalith repositioning maneuver, and the most common approach is the Epley maneuver ( 4). PC-BPPV is usually diagnosed by the means of the Dix–Hallpike test, which is considered positive when it triggers vertigo symptoms as well as torsional and vertical nystagmus ( 3). Approximately 60-90% of BPPV involves the posterior canal (PC-BPPV) ( 2). It is usually caused by otoconia that are dislodged from the otolith macula beds and become trapped in the semicircular canal ( 1). The modified Epley maneuver group had fewer residual symptoms than that of the Epley maneuver group 1 week after treatment of PC-BPPV ( p 0.05).Ĭonclusions: The modified Epley maneuver has a satisfactory therapeutic efficacy with less residual symptoms and could be recommended as a self-treatment for patients with PC-BPPV.īenign paroxysmal positional vertigo (BPPV) is the common cause of peripheral vertigo. Results: It was found that the modified Epley maneuver group had a higher resolution rate than that of the Epley maneuver group in the treatment of PC-BPPV after 1 day of the initial maneuver ( p 0.05). We analyzed the resolution rate (1 day and 1 week), residual symptoms after the maneuver, and adverse effects. All patients were randomized into the Epley maneuver group ( n = 77) and modified Epley maneuver group ( n = 78). ![]() ![]() ![]() Methods: The study recruited 155 patients with PC-BPPV. ![]() Objectives: The purpose of this study is to investigate a modified Epley maneuver for self-treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV).
