A Synchrotron and Micro-CT Study of the Human Endolymphatic Duct System: Is Meniere's Disease Caused by an Acute Endolymph Backflow?

open access: yesFrontiers in Surgery, 2021
Background: The etiology of Meniere's disease (MD) and endolymphatic hydrops believed to underlie its symptoms remain unknown. One reason may be the exceptional complexity of the human inner ear, its vulnerability, and surrounding hard bone.

Evaluation of the usefulness of three-dimensional optical coherence tomography in a guinea pig model of endolymphatic hydrops induced by surgical obliteration of the endolymphatic duct [PDF]

open access: yes, 2015
Optical coherence tomography (OCT) has advanced significantly over the past two decades and is currently used extensively to monitor the internal structures of organs, particularly in ophthalmology and dermatology.

VOLT: a novel open-source pipeline for automatic segmentation of endolymphatic space in inner ear MRI [PDF]

open access: yes, 2020
BACKGROUND Objective and volumetric quantification is a necessary step in the assessment and comparison of endolymphatic hydrops (ELH) results. Here, we introduce a novel tool for automatic volumetric segmentation of the endolymphatic space (ELS) for ELH

Comparative Histopathologic Analysis of Inner Ear Damage in Meningitis: Otogenic Versus Meningogenic Routes

open access: yesThe Laryngoscope, Volume 135, Issue 2, Page 864-872, February 2025.
A comparative study distinguishing histopathologic patterns of inner ear changes between meningogenic and otogenic routes in meningitis cases. Otogenic cases displayed a higher prevalence of changes in the spiral ligament and signs of early ossification, whereas meningogenic cases associated with a higher degree of vestibular damage.

Fluid–Structure Interaction Analysis of Trapezoidal and Arc‐Shaped Membranes Mimicking the Organ of Corti

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 1, January 2025.
In the numerical analysis, solving a three‐dimensional fluid–structure interaction problem, resonant frequencies of the trapezoidal membrane are evaluated. Using the modified elastic modulus for the membrane, the vibration modes and resonant frequencies in liquids are in good agreement with experimental results.

Modulation of hearing function following the downgrading or upgrading of endolymphatic hydrops in Meniere's disease patients with endolymphatic duct blockage.

open access: yesPLoS ONE, 2020
The present study was to investigate the dynamics of endolymphatic hydrops (EH) and hearing function, and explore whether the hearing loss is caused by EH alone and whether the hearing function can be modulated by changes in the EH.

Relationship Between the Extent of Endolymphatic Hydrops and the Severity and Fluctuation of Audiovestibular Symptoms in Patients With Meniere's Disease and MRI Evidence of Hydrops [PDF]

open access: yes, 2018
Objective:To characterize the short-, middle-, and long-term occurrence of vertigo attacks in a large population of Meniere's disease (MD) and to investigate the relationship between the extent of endolymphatic hydrops (ELH) and the severity of ...
