Diagnosis and management of posterior semicircular canal benign paroxysmal positional vertigo: A practical approach

ObjectivesTo identify variables affecting outcome in patients with unilateral and bilateral BPPV.Materials and methodsRetrospective review of 220 patients diagnosed with posterior SCC underwent treatment successfully with Canalith Repositioning Maneuver. Bilateral and severe cases received medical treatment before starting the maneuver. Scheme for management of the cases had been settled.ResultsOne hundred seventy-four patients (74.5%) as the first BPPV episode while 25.5% with recurring episodes. Significant improvement was reported in 84% of patients. Etiology is not playing a role in unilateral or bilateral BPPV. Patients presented with bilateral BPPV were classified into true or unilateral mimicking bilateral BPPV. 46.7% of the patients reported sleeping using one pillow. Daily routine Brandt–Daroff exercises after the success of CRM affect the rate of recurrence.ConclusionCanalith repositioning Maneuver provides rapid relief of symptoms of BPPV. Patients with bilateral or severe BPPV required a special protocol to reach complete relief. In addition daily routine Brandt–Daroff exercises decrease the recurrence rate.
