Two hundred and sixty-three patients with BPPV (2009-2014), confirmed by videonystagmography (VNG), were enrolled in the study. Patients' charts were reviewed. They were grouped as those with or without migraine. Distribution of gender, age, duration of symptoms and affected side were reviewed. Two hundred and thirty-one patients with no migraine were identified.

Thirty-two patients (11.4%) with migraine were identified. Diagnosis and classification of migraine and its differentiation from other type of headaches was based on third edition of International classification of headache disorders (ICHD-III beta) by international headache society (IHS). All patients with migraine had migrainous headache with or without aura and they all were diagnosed in our institution and followed by our neurology staff.

Patients with posterior canal BPPV (PC-BPPV) were treated with Epley maneuver. Patients with superior canal (SC-BPPV) were treated with Li or reverse Epley maneuver. Patients with lateral canal (LC) apogeotropic or geotropic nystagmus were treated with Barbeque, Semont's or Gufoni maneuvers. If geotropic or ageotropic type nystagmus is equal intensity on both sides. The involved side was determined according to the patient sense of disturbance or lying down positioning test. If the patient has involvement of both sides according to Dix-Hallpike maneuver. Therapeutic maneuver was applied to the more severe side. All patients were re-evaluated at maximum 7 days.

Every patient with BPPV who had positional nystagmus during Dix-Hallpike and head-roll provocative maneuvers will be treated with Epley or barbeque particle re-positioning maneuvers. Balance (positional nystagmus) of patients 7 days after re-positioning maneuvers will be assessed.
