Into the dark: patterns of middle ear adaptations in subterranean eulipotyphlan mammals [PDF]

Royal Society Open Science, 2017
Evolution of the middle ear ossicles was a key innovation for mammals, enhancing the transmission of airborne sound. Radiation into various habitats from a terrestrial environment resulted in diversification of the auditory mechanisms among mammals ...

Anatomical, Histological, and Morphometrical Features of the Auditory Ossicles in Dog Fetuses at 55–56 Days of Gestation

Veterinary Sciences
This study examines the auditory ossicles of 55–56-day gestational age dog fetuses and shows that the basic three-bone middle ear pattern is already present, but the bones remain partly cartilaginous and are actively ossifying.

FGF23 deficiency leads to mixed hearing loss and middle ear malformation in mice.

PLoS ONE, 2014
Fibroblast growth factor 23 (FGF23) is a circulating hormone important in phosphate homeostasis. Abnormal serum levels of FGF23 result in systemic pathologies in humans and mice, including renal phosphate wasting diseases and hyperphosphatemia. We sought

Allogenic Auditory Ossicle in Tympanoplasty.

Practica Oto-Rhino-Laryngologica, 1994
The results of tympanoplasty using allogenic auditory ossicle (incus) were studied in 30 ears 6 or more months after surgery. The allogenic auditory ossicles were supplied by Pfrimmer-Viggo Gmbh & Co in individual sterile packs and used for columellae in type III or IV tympanoplasty. Hearing success was defined as a postoperative pure tone threshold of

Ossicular Bone Damage and Hearing Loss in Rheumatoid Arthritis: A Correlated Functional and High Resolution Morphometric Study in Collagen-Induced Arthritic Mice.

PLoS ONE, 2016
Globally, a body of comparative case-control studies suggests that rheumatoid arthritis (RA) patients are more prone to developing hearing loss (HL). However, experimental evidence that supports this hypothesis is still lacking because the human auditory

Study on the Prosthesis Structural Design and Vibration Characteristics Based on the Conduction Effect of Human Middle Ear

Applied Bionics and Biomechanics, 2020
As a bridge from the sound signal in the air to the sound perception of the inner ear auditory receptor, the tympanic membrane and ossicular chain of the middle ear transform the sound signal in the outer ear through two gas-solid and solid-liquid ...

The development of a didactic model to facilitate the understanding of the components and anatomical relations of the middle ear

Medicina, 2022
The middle ear is important from an anatomical and clinical point of view, seeing that it contains and allows the passages of structures, in addition to establishing relations with other regions of the head.

Glia-related mechanisms in the anteroventral cochlear nucleus of the adult rat in response to unilateral conductive hearing loss

Frontiers in Neuroscience, 2014
Conductive hearing loss causes a progressive decline in cochlear activity that may result in functional and structural modifications in auditory neurons.
