Semicircular canal plane head impulses detect absent function of individual semicircular canals.
We studied the human vestibulo-ocular reflex (VOR) in response to head 'impulses': brief, unpredictable, passive, high-acceleration (up to 4000 degrees/s2), low-amplitude (20-30 degrees) head rotations. We delivered the head impulses approximately in the plane of the semicircular canal (SCC) being tested. To test the anterior and posterior SCCs, the head impulses were delivered in a diagonal pl...
متن کاملApplication of the video head impulse test to detect vertical semicircular canal dysfunction.
OBJECTIVE The video head impulse test (vHIT) is a useful clinical tool to detect semicircular canal dysfunction. However, so far, vHIT has been limited to measurement of the function of the horizontal semicircular canals. The goal of this study was to determine if vHIT can detect vertical semicircular canal dysfunction. STUDY DESIGN Horizontal and vertical eye movements were recorded in respo...
متن کاملAbsent semicircular canals in CHARGE syndrome: radiologic spectrum of findings.
BACKGROUND AND PURPOSE This paper describes the CT findings that characterize the middle and inner ear anomalies in coloboma, heart defects, choanal atresia, mental retardation, genitourinary, and ear anomalies (CHARGE) syndrome. With this information, neuroradiologists will be better prepared to provide clinically relevant information to their referring physicians regarding this rare syndrome....
متن کاملEnhanced otolithic function in semicircular canal dehiscence.
The enhanced sound- and vibration-induced vestibular evoked myogenic potentials (VEMPs) and their lower threshold in patients with a thinning of the bony wall of the superior semicircular canal (superior canal dehiscence, SCD) have been interpreted as being due to the dehiscence allowing sound and vibration to activate, unusually, the receptors of the dehiscent semicircular canal. We report a p...
متن کاملSemicircular Canal Fibrosis as a Biomarker for Lateral Semicircular Canal Function Loss
BACKGROUND AND PURPOSE Radiological abnormalities at the level of the semicircular canals are frequently observed without known correlation to a pathologic condition or function. They include narrowing or sclerosis on computed tomography (CT) and narrowing or signal loss on T2-weighted magnetic resonance imaging (MRI). Our hypothesis was that these radiological abnormalities at the level of the...
