Congenital Aplasia of the Semicircular Canals
Otology & Neurotology, 2003To describe the underrecognized inner ear malformation characterized by complete aplasia of the labyrinthine semicircular canals associated with a relatively well-formed cochlea, to investigate its relationship with known syndromic forms of hearing loss, and to hypothesize regarding the potential embryopathogenesis of this anomaly.A retrospective case ...

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.

Acoustic Stimulation of the Semicircular Canals
Otolaryngologic Clinics of North America, 1995Stimulation of the semicircular canals provides an alternative method of vibratory stimulation of the auditory system. The frequency response characteristics of stimulation of the tympanic membrane, malleus, stapes, round window, and fenestrated semicircular canal are presented in this article.

The biomechanics of the semicircular canals
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1988A mathematical model for the unsteady fluid-dynamic response of the semicircular canals is presented. The endolymph is assumed to be an incompressible Newtonian fluid, and the presence and effects of both the utricle and the cupula are specifically accounted for.

Osteoma of the lateral semicircular canal
Acta Oto-Laryngologica, 2006Osteomas are benign, slow growing tumors of bone that occur almost exclusively in the craniofacial region. They are uncommon in the temporal bone. Surgical excision is indicated in symptomatic cases. An osteoma arising from the lateral semicircular canal growing into the mastoid cavity is extremely rare and usually discovered on routine radiography. We

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

Displacement configuration of semicircular canal cupulae
Neuroscience, 1979Abstract Cupula displacement had traditionally been portrayed as a wiper motion of the cupula hinged at its base. In this study, semicircular canals of the bullfrog, which had been carefully dissected, were analyzed for cupula motion during compression of the canal wall.

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.
