Optimization of an MRI protocol for non-contrast saccule and utricle visualization at 1.5T
ISMRM Annual Meeting, 2023This 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 ...

Otolith mass asymmetries in the utricle and saccule of flatfish
Journal of Vestibular Research, 2005The otolith mass of the saccules and utricles of plaice, Pleuronectes platessa (n = 39) and turbot, Psetta maxima (n = 21) was measured using an electronic microbalance. In the right-eyed plaice, the left utricular otoliths were found to be significantly heavier than the right (p < 0.0001), whereas no significant difference was found between left ...

Function of semicircular canals, utricles and saccules in deaf children
Acta Oto-Laryngologica, 2004To 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 ...

Morphometry of otoconia in the utricle and saccule of developing Japanese quail
Hearing Research, 2004The 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 ...

Utricle, Saccule, and Cochlear Duct in Relation to Stapedotomy
Annals of Otology, Rhinology & Laryngology, 1991This 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
Acta Oto-Laryngologica, 1977The 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 Interaction Between the Utricle and the Saccule
Acta Oto-Laryngologica, 1970By using a combination of series of investigations on human subjects in the human centrifuge and neurophysiological experiments on the cat it has been possible to solve the problem of the influence...

Studies addressing structure-function relationships of the fish auditory system during development are sparse compared to other taxa. The Batrachoididae has become an important group to investigate mechanisms of auditory plasticity and evolution of auditory-vocal systems.

New Diagnostic Tests for the Function of Utricles, Saccules and Somatic Graviceptors
Acta Oto-Laryngologica, 1995Clinical 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 ...

The Effect of CO2and KTP laser on the cat saccule and utricle
The Laryngoscope, 2009AbstractObjectives/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 ...
