The Age-Related Orientational Changes of Human Semicircular Canals [PDF]

Clinical and Experimental Otorhinolaryngology, 2016
Objectives Some changes are found in the labyrinth anatomy during postnatal development. Although the spatial orientation of semicircular canals was thought to be stable after birth, we investigated the age-related orientational changes of human ...

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

J. Biomech. 37 (2004)1137 --1146, 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.

Fluidmechanics of semicircular canals - revisited [PDF]

Zeitschrift für angewandte Mathematik und Physik, 2018
.: In this work we find the exact solution for the flow field in a semicircular canal which is the main sensor for angular motion in the human body. When the head is rotated the inertia of the fluid in the semicircular canal leads to a deflection of ...

Occlusion of two semicircular canals does not disrupt normal hearing in adult mice [PDF]

Frontiers in Neurology, 2022
Vertigo is a debilitating disease affecting 15–20% of adults worldwide. Vestibular peripheral vertigo is the most common cause of vertigo, often due to Meniere's disease and benign paroxysmal positional vertigo.
