Contribution of Even/Odd Sound Wave Modes in Human Cochlear Model on Excitation of Traveling Waves and Determination of Cochlear Input Impedance

open access: yesAcoustics, 2022
Based on the Navier–Stokes equation for compressible media, this work studies the acoustic properties of a human cochlear model, in which the scala vestibuli and scala tympani are filled with compressible perilymph.

Noise-Induced Perilymph Fistula [PDF]

open access: yesEar, Nose & Throat Journal, 2006
Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions. In this article, we describe a case of perilymph fistula that featured one of its more rare causes: acoustic trauma—specifically, damage from a loud blast from the ...

Pharmacokinetic Properties of Adenosine Amine Congener in Cochlear Perilymph after Systemic Administration [PDF]

open access: yes, 2017
Noise-induced hearing loss (NIHL) is a global health problem affecting over 5% of the population worldwide. We have shown previously that acute noise-induced cochlear injury can be ameliorated by administration of drugs acting on adenosine receptors in ...

Computed tomographic diagnosis and treatment of pneumolabyrinth in a mare with temporohyoid osteoarthropathy

open access: yesEquine Veterinary Education, EarlyView.
Summary Pneumolabyrinth, which is the presence of gas within the labyrinth of the inner ear, can be associated with severe peripheral vestibular signs. This report describes a case of pneumolabyrinth in a horse that presented with vestibular ataxia. An 8‐year‐old Quarter Horse mare that presented with cranial nerve VII deficits underwent a standing ...

Intralabyrinthine Penetrating Ventilation Tube with Preservation of Hearing: An Unusual Clinical Situation

open access: yesInternational Archives of Otorhinolaryngology, 2015
Introduction Traumatic perilymphatic fistula is not a rare event with regards to sport activities or traffic accident. However, iatrogenic damage to the inner ear can occur following the common use of grommets and ventilation tube insertion.

The cochlear morphometry compendium: High‐resolution synchrotron measurements and normative reference values

open access: yesJournal of Anatomy, EarlyView.
In this study, 100 cadaveric temporal bones underwent synchrotron radiation phase‐contrast imaging. Images were segmented to produce 3D surface mesh models for morphological analysis. Measurements obtained for all cochleae included: standard gross dimensions, various cochlear lengths including basilar membrane length, detailed intracochlear scalar ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Cytokine Levels in Inner Ear Fluid of Young and Aged Mice as Molecular Biomarkers of Noise-Induced Hearing Loss

open access: yesFrontiers in Neurology, 2019
Sensorineural hearing loss (SNHL) is the most common sensory deficit worldwide, frequently caused by noise trauma and aging, with inflammation being implicated in both pathologies.

Quantifying Soft‐Surgery in Cochlear Implantation: Multimodal Data From 30 International Specialists

open access: yesThe Laryngoscope, Volume 136, Issue 9, Page 3990-3997, September 2026.
Objective data from 30 specialist cochlear implant surgeons showed that surgical handling strongly influences intracochlear mechanical stress during implantation. Surgeons with fewer than 50 lifetime insertions performed significantly worse than more experienced colleagues, while self‐assessment did not reflect objective performance in any group ...
