Isotopic Values of Prenatal Development: δ13C and δ15N Variation in Early‐Formed Human Tissues

open access: yesAmerican Journal of Biological Anthropology, Volume 189, Issue 4, April 2026.
ABSTRACT Objectives Carbon (δ13C) and nitrogen (δ15N) isotope analysis illuminates diet and physiology in the past, yet interpretation is complicated by development and tissue‐specific collagen formation. This study tests whether systematic isotopic offsets occur between auditory ossicles, deciduous dentin, long bones, and ribs in individuals who died ...

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 989-1004, April 2026.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Histological Changes of the Middle Ear Ossicles Harvested During Cholesteatoma Surgery

open access: yesActa Medica, 2016
Background: In the cholesteatoma surgery ossicles can be replaced to reconstruct middle ear function. It is important that these ossicles are free of squamous epithelium, to prevent residual disease. This study focuses on the histological findings of the

Outcomes of Inverted Tympanomeatal Flap Elevation for Large Anterior Tympanic Membrane Perforations in Narrow External Auditory Canals

open access: yesLaryngoscope Investigative Otolaryngology, Volume 11, Issue 2, April 2026.
ABSTRACT Background and Objective Anterior tympanic membrane perforations—particularly in patients with a narrow external auditory canal—remain technically challenging due to limited visualization and inadequate anterior support. The inverted tympanomeatal flap technique has been proposed to address these issues, but evidence is limited.

Morphology and function of Neandertal and modern human ear ossicles. [PDF]

open access: yes, 2016
The diminutive middle ear ossicles (malleus, incus, stapes) housed in the tympanic cavity of the temporal bone play an important role in audition. The few known ossicles of Neandertals are distinctly different from those of anatomically modern humans ...

In vivo imaging of middle-ear and inner-ear microstructures of a mouse guided by SD-OCT combined with a surgical microscope [PDF]

open access: yes, 2014
We developed an augmented-reality system that combines optical coherence tomography (OCT) with a surgical microscope. By sharing the common optical path in the microscope and OCT, we could simultaneously acquire OCT and microscope views.
