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.

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,

Use of porcine small intestinal submucosa for pediatric endoscopic tympanic membrane repair

World Journal of Otorhinolaryngology-Head and Neck Surgery, 2017
Tympanic membrane perforationsoccur frequently in children, and can result in hearing loss, otorrhea, pain, and cholesteatoma. Due to the narrower ear canal in children, a postauricular incision is often needed to access the tympanic membrane for ...

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

External Acoustic Meatus Approach for Ultrasonographic Evaluation of the Temporomandibular Joint: An Anatomical Validation and Proof‐of‐Concept Study

Clinical Anatomy, EarlyView.
ABSTRACT Temporomandibular disorders (TMD) represent a public health problem, affecting 31% of adults and the elderly and 11% of children and adolescents. Interest is growing in using ultrasound to evaluate the temporomandibular joint (TMJ). However, researchers need to standardize a reliable method.

Ultrastructural alterations of the tympanic membrane in retraction pockets from patients with chronic otitis media

Polish Journal of Pathology, 2021
Chronic otitis media with a retraction pocket is one of the forms of chronic otitis media that predisposes to cholesteatoma. The aim of our study was to determine the extent and type of changes in the tympanic membrane fragments which were surgically ...

Anatomy of the Soft Palate and Its Role in Upper Airway Function: A Narrative Review

Clinical Anatomy, EarlyView.
ABSTRACT The soft palate is a complex anatomical structure, located at the posterior aspect of the oral and nasal cavities, able to dynamically create valve closure of the nasal and the oral cavities. Its precise movement is critical for speech, swallowing, and respiration. Despite its functional importance, detailed characterization of its constituent

A Combination Hyaluronic Acid-Collagen Fiber Scaffold for Tympanic Membrane Repair

, 2022
Tympanic membrane perforation (TMP) can cause recurrent ear infections and chronic TMP. Treatments designed to repair TMP involve reconstruction of the TM with autologous tissue grafts. These autologous grafts have limitations.

The concept of an artificial tympanic membrane [PDF]

, 1984
A review is given of the development of the concept of an artifical tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly ...
