Semicircular canal dehiscence

2018
This chapter discusses Minor, Solomon, Zihreich, and Zee’s 1998 paper on semicircular canal dehiscence including the design of the study (outcome measures, results, conclusions, and a critique).

The biomechanics of the semicircular canals

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1988
A 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, 2006
Osteomas 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, 2013
We 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, 1979
Abstract 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

2008
After 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, 1974
On 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.

The function of the semicircular canals

1983
The three semicircular canals lie at 90 degree angles to each other. The crista of each semicircular canal is stimulated by rotatory movement in its own plane. This enables perception of rotatory movement in any plane. These canals also respond to non-natural stimuli, such as cold or warm water applied in the ear canal, or electrical stimulation to the
