Membrane Stress in the Human Labyrinth and Meniere Disease: A Model Analysis

International Archives of Otorhinolaryngology, 2015
Introduction The nature and extent of membrane damage encountered in Meniere disease remains unexplained. Pressure-induced membrane stress may underlie the characteristic hydropic distention.

Acute histological reactions in the otolith organs to inner ear drug delivery through a cochlear implant

Frontiers in Neurology
IntroductionCochlear implantation is currently regarded as a safe and minimally invasive procedure. However, cochlear implantation can have an impact on vestibular function, despite the lack of correlation between patient symptomatology and damage in ...

First evolutionary insights into the human otolithic system

Communications Biology
The human otolithic system (utricle and saccule), housed within the bony vestibule of the inner ear, establishes our sense of balance in conjunction with the semicircular canals.

Vestibular Function Pre‐ and Post‐cochlear Implantation in Adult Patients With Inner Ear Malformations: A Retrospective Cohort Study

Sensory Neuroscience, Volume 2, Issue 3, September 2026.
This study investigated vestibular function in 129 adult patients with inner ear malformations (IEMs). The superior semicircular canal showed less impairment than the horizontal and posterior canals. Notably, cochlear implantation did not significantly exacerbate vestibular dysfunction at 12 months postoperatively.

Release and elementary mechanisms of nitric oxide in hair cells

, 2010
The enzyme nitric oxide (NO) synthase, that produces the signaling molecule NO, has been identified in several cell types in the inner ear. However, it is unclear whether a measurable quantity of NO is released in the inner ear to confer specific ...

First evidence of the link between internal and external structure of the human inner ear otolith system using 3D morphometric modeling

Scientific Reports, 2023
Our sense of balance is among the most central of our sensory systems, particularly in the evolution of human positional behavior. The peripheral vestibular system (PVS) comprises the organs responsible for this sense; the semicircular canals (detecting ...
