<p>Clinical features of benign paroxysmal positional vertigo in Western Turkey</p>

Abstract

Background: It was the aim of this study to analyze the clinical manifestations, the incidence of each variant and the co-morbid 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.
