Semicircular canals shed light on bottleneck events in the evolution of the Neanderthal clade. [PDF]

Nat Commun
Revealing the evolutionary processes which resulted in the derived morphologies that characterize the Neanderthal clade has been an important task for paleoanthropologists. One critical method to quantify evolutionary changes in the morphology of hominin

Visual perception of the osseous labyrinth rendered from micro-CT scans of the petrous bone [PDF]

Folia medica Cracoviensia, 2017
Grayscale images comparing to the color images may have less of visual information necessary for easy recognition of the anatomical structures. Although micro-CT scanners deliver images of ultra-high resolution, application of false-colors to the ...

Is endolymphatic hydrops, as detected in MRI, a truly cochleocentric finding? [PDF]

Front Neurol
IntroductionThe most common histopathological finding in Ménière’s disease (MD) is endolymphatic hydrops (EH), which involves the dilation of the membranous labyrinth. The direct relationship between EH and MD is debated, although EH plays a crucial role

The specialized inner ear labyrinth of worm-lizards (Amphisbaenia: Squamata). [PDF]

PLoS One
High-resolution computed tomography (HRCT) has become a widely used tool for studying the inner ear morphology of vertebrates. Amphisbaenians are one of the most specialized groups of fossorial reptiles but are poorly understood relative to other ...

Advanced Imaging of the Vestibular Endolymphatic Space in Ménière's Disease

Frontiers in Surgery, 2021
The diagnosis of “definite” Méniére's disease (MD) relies upon its clinical manifestations. MD has been related with Endolymphatic Hydrops (EH), an enlargement of the endolymphatic spaces (ES) (cochlear duct, posterior labyrinth, or both).
