Dye Tracking Following Posterior Semicircular Canal or Round Window Membrane Injections Suggests a Role for the Cochlea Aqueduct in Modulating Distribution

Frontiers in Cellular Neuroscience, 2019
The inner ear houses the sensory epithelium responsible for vestibular and auditory function. The sensory epithelia are driven by pressure and vibration of the fluid filled structures in which they are embedded so that understanding the homeostatic ...

Visualization of the Membranous Labyrinth and Nerve Fiber Pathways in Human and Animal Inner Ears Using MicroCT Imaging

Frontiers in Neuroscience, 2018
Design and implantation of bionic implants for restoring impaired hair cell function relies on accurate knowledge about the microanatomy and nerve fiber pathways of the human inner ear and its variation.

Endolymphatic Potential Measured From Developing and Adult Mouse Inner Ear

Frontiers in Cellular Neuroscience, 2020
The mammalian inner ear has two major parts, the cochlea is responsible for hearing and the vestibular organ is responsible for balance. The cochlea and vestibular organs are connected by a series of canals in the temporal bone and two distinct ...

Identification of Potential Meniere's Disease Targets in the Adult Stria Vascularis

Frontiers in Neurology, 2021
The stria vascularis generates the endocochlear potential and is involved in processes that underlie ionic homeostasis in the cochlear endolymph, both which play essential roles in hearing.

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

Frontiers 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.

Normal Serum Levels of Otolin-1 in Patients with Meniere Disease in Remission

International Archives of Otorhinolaryngology, 2023
Introduction Degenerative changes in the otolithic organs have been theorized to be caused by the mechanical obstruction to endolymphatic flow, possibly resulting in endolymphatic hydrops (ELH).

Development of cochlear spiral ligament fibrocytes of the common marmoset, a nonhuman model animal

Scientific Reports, 2023
Spiral ligament fibrocytes generate potassium gradients, which hair cells require to convert mechanical sound waves into electrical palsy. Together with the stria vascularis, they regulate endolymph electrolyte homeostasis.

Missing perilymph but leaking blood-endolymph and vestibulocochlear nerve barriers in idiopathic sudden sensorineural hearing loss: A case study

Journal of Otology, 2020
Objectives: To evaluate the pathological changes in the blood-perilymph, blood-endolymph, and blood-nerve barriers of a patient with idiopathic sudden sensorineural hearing loss (SSNHL).

Stem Cells Injected into the Deaf Rat Cochlea via Round Window Could Survive for at Least One Week in the Endolymph

Otorhinolaryngology and Facial Plastic Surgery, 2022
Background: Noise-induced hearing loss (NIHL) is caused by chronic exposure to high-intensity sound. Although noise hazard has been extensively studied in the past decades, cochlear implants and hearing aids are only safe and clinically effective ...

Three-Dimensional Volumetric Measurement of Endolymphatic Hydrops in Meniere's Disease

Frontiers in Neurology, 2021
Objective: We used volumetric three-dimensional (3D) analysis to quantitatively evaluate the extent of endolymphatic hydrops (EH) in the entire inner ear.
