Flexibility within the middle ears of vertebrates [PDF]

open access: yes, 2012
Introduction and aims: Tympanic middle ears have evolved multiple times independently among vertebrates, and share common features. We review flexibility within tympanic middle ears and consider its physiological and clinical implications.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

open access: yes, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

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, EarlyView.
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 ...

Doppler optical coherence tomography as a promising tool for detecting fluid in the human middle ear

open access: yesCurrent Directions in Biomedical Engineering, 2016
The treatment of otitis media requires classifying the effusion in the tympanic cavity for choosing appropriate therapeutic strategies. Otoscopic examination of the middle ear depends on the expertise of the physician and is often hampered in case of ...

Development of the occipitopetrosal junctions: A histological study using human fetuses

open access: yesThe Anatomical Record, EarlyView.
Abstract The temporal bone petrosa is connected to the occipital bone at two sites: one junction with the basilar part (medial junction) and another with the lateral part (lateral junction). Using histological specimens from 45 human fetuses (approximately 7–39 weeks of gestational age or GA), we aimed to describe possible changes in histology and ...

Endoscopic evaluation of tympanic isthmus patency and its effect on success rate of myringoplasty in tubotympanic type of chronic suppurative otitis media

open access: yesThe Egyptian Journal of Otolaryngology
Background Chronic suppurative otitis media (CSOM) involves persistent middle ear inflammation, often leading to tympanic membrane perforation and hearing loss. Tympanic isthmus patency is key to middle ear ventilation, influencing tympanoplasty outcomes.

Noncholesteatomatous Cyst of the Tympanic Membrane: A Nonpublished Entity?

open access: yesCase Reports in Otolaryngology, 2015
Introduction. The presence of a serous cyst in the tympanic membrane implies the description of a new or unpublished entity based on our knowledge whose origin may be very unlikely explained on actual embryologic and anatomic background.
