Cupulolithiasis of the horizontal semicircular canal
European Archives of Oto-Rhino-Laryngology, 2011To clarify whether positional nystagmus of horizontal cupulolithiasis contains vertical and torsional components, and to quantify the asymmetry, we analyzed nystagmus in four positions (healthy-ear-down, affected-ear-down, supine, nose-down), using 3-dimensional video-oculography.

Congenital Dehiscence in the Posterior Semicircular Canal
Otology & Neurotology, 2013Posterior semicircular canal dehiscence (PSCD) may be of congenital origin.PSCD is characterized by the lack of bone coverage, which results in its lumen being exposed to the meninges of the posterior cranial fossa or to the gulf of the jugular vein. It has an incidence of 0.2%.

The crista of the semicircular canal is a receptor of rotatory movement, which enables its perception in any plane of rotation. Three semicircular canals, horizontal, anterior and posterior, open into the utricle.

Cupulolithiasis of the posterior semicircular canal
American Journal of Otolaryngology, 2013We sometimes experience patients with persistent torsional/vertical (upbeating) positional nystagmus in the head-hanging position. We have been convinced of the existence of cupulolithiasis of the posterior semicircular canal because such cases reveal persistent torsional/vertical (downbeating) positional nystagmus in the nose-down position.In order to

THE cephalopods and fishes are rivals as fast-moving predators and they show many parallel adaptations1. We present here evidence that in squids and cuttlefishes the statocysts possess semicircular canals, though of rather imperfect form. Animals that move quickly need to monitor angular rotation in order to allow appropriate adjustments of the eyes as

Impulsive testing of semicircular canal function
2008After acute vestibular loss in humans or animals, eye-movement responses to rapid horizontal ipsilesional head rotations ("head impulses") show that there is severe, permanent impairment of the angular vestibulo-ocular reflex. The basis for this appears to be an inhibitory saturation of ipsilesional vestibular nerve, and perhaps vestibular nucleus ...

My Trip through the Semicircular Canals
The American Journal of Nursing, 1974On a Monday evening, without warning, I entered the labyrinthine world of the inner ear. I had worked my usual day at the local hospital, made supper and had done some household chores. About 7:30 P.M. I noticed a dull roar in my left ear. Within an hour, the roar had become so deafening that I was dizzy.
