Function of semicircular canals, utricles and saccules in deaf children

open access: closedActa Oto-Laryngologica, 2004
To study vestibular function in deaf children.In 36 deaf children the function of the semicircular canals, saccules and utricles was measured by means of caloric testing, recordings of vestibular-evoked myogenic potentials (VEMPs) and measurements of the subjective visual horizontal (SVH) at different body tilts, respectively.In total, 30% of subjects ...

Optimization of an MRI protocol for non-contrast saccule and utricle visualization at 1.5T

open access: closedISMRM Annual Meeting, 2023
This study evaluates the feasibility of different approaches for the visualization of endolymphatic content in inner ear structures on 1.5T MR systems without the need of contrast injection. The results show that using an optimized high-resolution 3D T2w sequence combined with DLR-based denoising tools it is possible to visualize the utricle and ...

Unilateral examination of utricle and saccule function

open access: closedJournal of Vestibular Research, 2003
Attention is directed towards the recently developed unilateral tests of saccular and utricular function. Together with the now widely used head-thrust test and the standard caloric test for semicircular canal function, these provide for a more comprehensive unilateral examination of labyrinth function.

Otolithic Membranes of the Saccule and Utricle in Man

open access: closedScience, 1967
The otolithic membranes of the human saccule and utricle can be prepared as whole mounts or surface specimens for microscopic examination. They are not simple, homogeneous, gelatinous structures as heretofore described. Instead, each shows a definite and characteristic fibrillar design, which appears to be correlated with the known cytoarchitectural ...

Morphometry of otoconia in the utricle and saccule of developing Japanese quail

open access: closedHearing Research, 2004
The development of otoconia in the utricular and saccular maculae from initial embryonic formation to adult stages was examined in Japanese quails. Both the morphology and size of the otoconia were quantified at different developmental stages. It was observed that the otoconia were initially formed on embryologic stage E5 in the saccule and E6 in the ...

New Diagnostic Tests for the Function of Utricles, Saccules and Somatic Graviceptors

open access: closedActa Oto-Laryngologica, 1995
Clinical tests that allow us to discriminate between utricular, saccular and somatic effects on gravity perception and control are desirable but wanting. A new test battery is presented which combines four experimental paradigms based on the subjective horizontal body position (SHP), namely, a test on a tiltable board and on a sled centrifuge under ...

S-100 immunoreactivity identifies a subset of hair cells in the utricle and saccule of a fish

open access: closedHearing Research, 1990
Certain hair cells of fish exhibit strong immunoreactivity to an S-100 antibody. By their spatial locations in the utricle and saccule, these hair cells appear to possess a relatively short kinocilium and a roughly ovoid cell shape. In the utricle, these cells are predominantly located in the striola.

Utricle, Saccule, and Cochlear Duct in Relation to Stapedotomy

open access: closedAnnals of Otology, Rhinology & Laryngology, 1991
This study was performed to determine the area in which and the circumstances under which stapedotomy can be relatively safely performed. Measurements were made from central areas of the medial surface of the stapedial footplate to the utricle, the saccule, and the cochlear duct in 10 normal and 11 otosclerotic temporal bones.

Freeze-Fracture Study of the Cell Junctions in the Utricle and Saccule

open access: closedActa Oto-Laryngologica, 1977
The maculae sacculi and utriculi of the chinchilla vestibular labyrinth have been studied by freeze-fracture method. In the replicas extensive zonulae occludentes have been found between sensory and supporting cells at the endolymphatic surface. Gap junctions are located between the supporting cells. Some intramembranous specializations of the synaptic

The Effect of CO2and KTP laser on the cat saccule and utricle

open access: closedThe Laryngoscope, 2009
AbstractObjectives/Hypothesis:To assess the potential carbon dioxide (CO2) and potassium‐titanyl‐phosphate (KTP) laser‐related trauma to the saccule and utricle in a cat model.Study Design:Basic science experiment utilizing cat model.Methods:Twelve adult male cats were divided into two groups—CO2and KTP—to assess the potential saccule and/or utricle ...
