Selective canal impairment on video-HIT in peripheral vestibular diseases
Dr. A. Castellucci
In collaboration with VIS - Vestibology Italian Society directed by Prof. Augusto Pietro Casani, we announce the webinar “Selective canal impairment on video-HIT in peripheral vestibular diseases”.
The introduction of modern tools assessing otolith and ampullary reflexes in the high-frequency domain (VEMPs and video-HIT, respectively) has enabled a fast functional analysis of all inner ear receptors, offering new interpretations for end-organs and afferents abnormalities detected in patients with cochleo-vestibular pathologies.
The literature review highlights how vestibular disorders could result in specific lesion patterns, including selective dysfunctions involving a single receptor.
A series of patients with isolated impairment of a semicircular canal at the video-HIT will be presented and discussed. Each selective canal dysfunction will be correlated to the remaining clinical-instrumental data and related inner ear pathology. The underlying hypothetical pathomechanism accounting for each single scenario will be provided, with the help of pertinent bibliographic support.
