Treatment of Geotropic Horizontal Canal Benign Paroxysmal Positional Vertigo

Treatment of Geotropic Horizontal Canal Benign Paroxysmal Positional Vertigo; Randomized Controlled Trial of Barbeque Rotation and Gufoni Maneuver

The purpose of this study was to compare the immediate efficacies of each treatment maneuvers in treatment of geotorpic horizontal canal benign paroxysmal positional vertigo (HC-BPPV).

A randomized prospective study of patients with HC-BPPV. Patients with geotropic type of HC-BPPV were randomized to one of each three treatment groups at their first clinic visit. These groups included the barbecue maneuver, Gufoni's maneuver, and sham group in geotropic HC-BPPV. Responsiveness of treatment maneuver was determined by positioning maneuver immediately after each treatment method based on resolves of vertigo and positional nystagmus.

Inclusion Criteria:

• a history of brief episodes of positional vertigo, direction-changing horizontal nystagmus beating toward the uppermost (apogeotropic nystagmus) ear in both the lateral head turning positions,
• no spontaneous nystagmus during upright sitting position
• absence of identifiable central nervous system disorders that could explain the positional vertigo and nystagmus

Exclusion Criteria:

• central positional nystagmus with identifiable CNS lesions that could explain the positional nystagmus
