Guidelines updated for benign paroxysmal positional vertigo
Neil Bhattacharyya, M.D., from Harvard Medical School in Boston, and colleagues reviewed the literature to update guidelines for BPPV. New evidence was included from two clinical practice guidelines, 20 systematic reviews, and 27 randomized controlled trials.
The authors made several strong recommendations, including that posterior semicircular canal BPPV should be diagnosed when vertigo associated with torsional, upbeating nystagmus is provoked by the Dix-Hallpike maneuver. Patients with posterior canal BPPV should be treated by or referred for treatment with a canalith repositioning procedure. For posterior canal BPPV, there was a strong recommendation against postprocedural postural restrictions. Recommendations also included use of the supine roll test to assess for lateral semicircular canal BPPV; differentiation of BPPV from other causes of imbalance, dizziness, and vertigo; assessing for factors that modify management; reassessment within one month to document resolution or persistence of symptoms; evaluation of persistent symptoms; and education of patients on the impact of BPPV in terms of safety, recurrence, and the importance of follow-up.
"In updating the guideline, it was our goal to do so utilizing a focused and transparent process, reconsidering more current evidence while ultimately factoring in BPPV treatments that result in improved quality of life for the patient," Bhattacharyya said in a statement.
Several authors disclosed financial ties to the pharmaceutical and medical device industries.
