BACKGROUND: It was the aim of this study to analyze the clinical manifestations, the incidence of each variant and the comorbid conditions of benign paroxysmal positional vertigo (BPPV) as well as the response to treatment. METHODS: One hundred and fifty-seven patients with BPPV were reviewed prospectively. An extensive neurotologic examination was performed. All patients were treated with an appropriate canalith repositioning maneuver (CRM). RESULTS: In 138 patients, the posterior canal (PC) was involved, in 14 patients, the horizontal canal (HC), in 2 patients, the anterior canal (AC), and in 3 patients, both the PC and HC. A history of head trauma was identified in 17 patients. In 1 patient sensorineural hearing loss on the affected side and in another bilateral peripheral vestibular loss was present. A history of migraine was reported in 21 cases. A resolution attributable to the first CRM was achieved in 132 patients. CONCLUSIONS: PC involvement was the most frequent type constituting 87.9% of all BPPV cases. HC, AC and mixed canal types were relatively rare constituting 8.9, 1.3 and 1.9% of the cases, respectively. Response to the first CRM was recorded in 84.1%. Association with migraine was recorded in 13.4% of the patients.
