Do single-session Epley maneuvers treat benign paroxysmal positional vertigo?

Area of Science:

• Otolaryngology
• Neurology
• Vestibular Disorders

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo, significantly impacting patient quality of life.
• Posterior canal BPPV (PC-BPPV) is the most frequent subtype of this peripheral vestibular condition.

Purpose of the Study:

• To evaluate the efficacy of a single modified Epley maneuver for PC-BPPV in an outpatient setting.
• To determine the necessity of a second Dix-Hallpike maneuver if the initial repositioning is unsuccessful.

Main Methods:

• A prospective study involving 75 patients diagnosed with PC-BPPV.
• Data collected included sociodemographics, BMI, and comorbidities.
• Success rates of the modified Epley maneuver were analyzed, with a second maneuver performed if needed within the same session.

Main Results:

• The modified Epley maneuver achieved a success rate of 77.3% in the initial treatment.
• No significant correlation was found between comorbidities, BMI, and maneuver success.
• A second maneuver was required for some patients who did not respond to the first attempt.

Conclusions:

• Repositioning maneuvers, like the Epley, are highly effective for PC-BPPV.
• Some patients present with resistant BPPV, necessitating repeat maneuvers within the same visit to avoid readmission.
• Further investigation into factors contributing to treatment failure is warranted for persistent cases.
