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

The 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

The 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 ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Anatomical Study and Classification of Foramina of the Squamous Part of the Temporal Bone

Clinical Anatomy, EarlyView.
ABSTRACT The postglenoid foramen (PGF) is a rarely reported anatomical variant of the temporal bone, with limited data on its morphology, prevalence, and clinical relevance, particularly in non‐European populations. This study aimed to investigate the anatomy and frequency of foramina located on the squamous part of the temporal bone, including the PGF,

Tomography of the vestibular aqueduct in ear disease [PDF]

, 1979
A controversy exists concerning whether or not roentgenographic narrowing or nonvisualization of the vestibular aqueduct is a specific sign for Meniere's disease. Of 190 ears that were evaluated, abnormal aqueducts were seen in 42.9% of ears with Meniere'

Recurrent Maxillary Ameloblastoma Presenting as an External Auditory Canal Mass

The Laryngoscope, EarlyView.
Ameloblastoma with temporal bone involvement is exceedingly rare, with no prior reports of external auditory canal presentation. This case report demonstrates successful multidisciplinary management with extensive skull base resection and adjuvant radiation therapy, emphasizing the role of proton therapy in achieving tissue‐sparing treatment and long ...
