Abstract

 

Objective: We reported the differentiation of vestibulo-ocular reflex (VOR) gains and saccades in a video head impulse test (VHIT) of the semicircular canals of 49 patients with vertigo. They were diagnosed with benign paroxysmal positional vertigo (BPPV).

 

Material and Methods: In total, we evaluated 49 patients who were referred to our clinic due to vertigo within the first 10 days based on history between June 2016 and February 2017; of these, 30 patients were diagnosed with vertical canal BPPV according to the Dix–Hallpike test and 19 with lateral canal BPPV using the Roll test. Patients were evaluated according to age, sex, presence of saccades, and VOR gains of all the semicircular canals.

 

Results: Overall, 17 patients were males and 32 were females. The age ranged between 23 and 73 years (mean age, 50 years). The VOR gains were normal in 17 (34%) patients. Based on the VHIT findings, 20 patients (40%) had low VOR gains in the vertical canal, 12 (24%) in the lateral canal. Saccades was determined in 20 patients with canal pathology.

 

Conclusion: History and provocation maneuver are gold standards in the diagnosis of BPPV. VHIT was affected by the applied power of the clinician and the angular position of the head. Consequently, this test can be used as supporting diagnostic test.
