Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different ...

Turning semicircular canal function on its head: dinosaurs and a novel vestibular analysis. [PDF]

PLoS ONE, 2013
Previous investigations have correlated vestibular function to locomotion in vertebrates by scaling semicircular duct radius of curvature to body mass. However, this method fails to discriminate bipedal from quadrupedal non-avian dinosaurs.

Semicircular canal biomechanics in health and disease

Journal of Neurophysiology, 2018
The semicircular canals are responsible for sensing angular head motion in three-dimensional space and for providing neural inputs to the central nervous system (CNS) essential for agile mobility, stable vision, and autonomic control of the ...

Bilateral semicircular canal aplasia

European Annals of Otorhinolaryngology, Head and Neck Diseases, 2013
Bilateral semicircular canal aplasia is extremely rare; discovery, when the cochlear-vestibular system is normal and there is no hearing loss, is serendipitous.Bilateral semicircular canal aplasia was serendipitously discovered in a 24-year-old male during assessment of unilateral mixed hearing loss with subnormal contralateral hearing.

A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]

, 2003
Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

The Mechanics of the Growing Semicircular Canal [PDF]

Journal of Experimental Biology, 1973
ABSTRACT The motion of the endolymph in the semicircular canal is described with the aid of a linear second-order system, comprising the applied angular acceleration and the linear displacement, the linear velocity and the linear acceleration of the endolymph.

Posterior Semicircular Canal Approach for Inner Ear Gene Delivery in Neonatal Mouse.

Journal of Visualized Experiments, 2018
Inner ear gene therapy offers great promise as a potential treatment for hearing loss and dizziness. One of the critical determinants of the success of inner ear gene therapy is to find a delivery method which results in consistent transduction ...

Development of a dynamic virtual reality model of the inner ear sensory system as a learning and demonstrating tool [PDF]

, 2009
In order to keep track of the position and motion of our body in space, nature has given us a fascinating and very ingenious organ, the inner ear. Each inner ear includes five biological sensors - three angular and two linear accelerometers - which ...
