Comparison of three diagnostic tests in detecting vestibular deficit in patients with peripheral vestibulopathy.

Objectives: This study aimed to evaluate the results of the video head impulse test and of the caloric and rotatory chair tests in patients with dizziness. Agreement between test results was assessed and the best protocol for detecting peripheral vestibulopathy was identified.

Methods: Participants comprised 116 patients, 75 with a peripheral vestibulopathy and 41 with non-peripheral vestibulopathy.

Normal Gain of VOR with Refixation Saccades in Patients with Unilateral Vestibulopathy.

Objective: To characterize the response in the video head-impulse test for the assessment of the vestibulo-ocular reflex (VOR) in patients because of vertigo and dizziness.

Materials And Methods: After rightward and leftward head impulses, the following results evaluated were: gain of the reflex and appearance of refixation saccades. A particular type of response (normal gain VOR and refixation saccades) was evaluated in a group of patients.

Otosclerosis among patients with dizziness.

Objective: The objective of this study was to identify patients with otosclerosis and to characterize its clinical presentation among patients examined at our hospital with vertigo as the primary and most distressing symptom.

Study Design: Retrospective chart review.

Setting: Tertiary medical center.
