Cancer of the External Auditory Canal [PDF]

open access: yesArchives of Otolaryngology–Head & Neck Surgery, 2002
To evaluate the outcome of surgery for cancer of the external auditory canal and relate this to the Pittsburgh staging system used both on squamous cell carcinoma and non-squamous cell carcinoma.Retrospective case series of all patients who had surgery between 1979 and 2000. Median follow-up was 47 months (range, 2-148 months).

Intraspecific variation of cochlear morphology in bowhead and beluga whales

open access: yesThe Anatomical Record, EarlyView.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Feline vestibular disorders. Part II: diagnostic approach and differential diagnosis. [PDF]

open access: yes, 1999
Results of a neurological examination usually permit localisation of a vestibular disorder to either the central or peripheral parts of the vestibular system. Many different disorders located in the same part of the vestibular system will produce similar

Association between superior semicircular canal dehiscence and other dehiscences in temporal bone

open access: yesFolia Morphologica, 2020
BACKGROUND: The study of the association between superior semicircular canal and other dehiscences in the temporal bone. MATERIALS AND METHODS: We have studied computed tomography of radiologically diagnosed people with superior or posterior semicircular

Paraganglioma of external auditory canal

open access: yesIndian Journal of Otolaryngology and Head and Neck Surgery, 2001
In the ear, paragangliomas are commonly found in the tympanic cavity or in juglar bulb. We, here, present a case of paraganglioma originating from the external auditory canal as it has not been reported in the world literature. The clinico-pathologic features of such a case has been described.

Statistical shape modeling of the human inner ear through micro‐computed tomography imaging

open access: yesThe Anatomical Record, EarlyView.
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

On the development of the chondrocranium and the histological anatomy of the head in perinatal stages of marsupial mammals [PDF]

open access: yes, 2017
An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides ...
