Anatomical Study and Classification of Foramina of the Squamous Part of the Temporal Bone

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The postglenoid foramen (PGF) is a rarely reported anatomical variant of the temporal bone, with limited data on its morphology, prevalence, and clinical relevance, particularly in non‐European populations. This study aimed to investigate the anatomy and frequency of foramina located on the squamous part of the temporal bone, including the PGF,

Measurement of the Mechanical Impedance of Ear Cartilage and Development of a Coupler for Vibrator Evaluation of Cartilage Conduction Hearing Aids

open access: yesApplied Sciences
Cartilage conduction hearing aids (CCHAs) are new devices that have attracted attention in recent years for external auditory canal atresia. In these devices, a vibrator is attached to the ear cartilage to transmit sound through vibration. In this study,

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.

The impact of using real ear measures to calculate prescriptive targets on hearing aid follow-up visits [PDF]

open access: yes, 2013
To fit hearing aids, estimated values are used to convert dB HL to dB SPL. This does not account for variance in ear canal shape and volume. Measured RECDs can change the NAL-NL1 targets. The purpose of this study was to evaluate if patients that deviate

A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei

open access: yesDevelopmental Dynamics, EarlyView.
Three populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

Micromotional studies of utricular and canal afferents [PDF]

open access: yes
The long-range goal of this research was to refine our understanding of the sensitivity of the vestibular components of the ear to very-low-amplitude motion, especially, the role of gravity in this sensitivity.
