Simultaneous Contralateral Vestibular Schwannoma and Middle Ear Paraganglioma Tumor [PDF]

, 2017
To the best of our knowledge, only 2 cases of a simultaneous contralateral vestibular schwannoma (VS) and middle ear paraganglioma (MEP) have previously been reported in literature.

Development of the occipitopetrosal junctions: A histological study using human fetuses

The Anatomical Record, EarlyView.
Abstract The temporal bone petrosa is connected to the occipital bone at two sites: one junction with the basilar part (medial junction) and another with the lateral part (lateral junction). Using histological specimens from 45 human fetuses (approximately 7–39 weeks of gestational age or GA), we aimed to describe possible changes in histology and ...

Noncholesteatomatous Cyst of the Tympanic Membrane: A Nonpublished Entity?

Case Reports in Otolaryngology, 2015
Introduction. The presence of a serous cyst in the tympanic membrane implies the description of a new or unpublished entity based on our knowledge whose origin may be very unlikely explained on actual embryologic and anatomic background.

Intraspecific variation of cochlear morphology in bowhead and beluga whales

The 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 ...

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.

Improving Tympanoplasty: Transverse External Auditory Canal Flap Advancement

Laryngoscope Investigative Otolaryngology
Objectives We conducted this study to investigate the clinical outcomes of a new self‐created technique for improving tympanoplasty. This technique, called the external auditory canal flap advancement method, aims to treat large tympanic membrane ...

Application of blood plasma enriched with platelet derived growth factors in experimental perforation of the tympanic membrane

Медицинский совет, 2019
Acute traumatic perforation of the tympanic membrane occupies a significant place in the structure of the pathology of the middle ear, since «persistent» perforation of the tympanic membrane is the main cause of chronic inflammation in the middle ear ...

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]

, 2017
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

The concept of an artificial tympanic membrane [PDF]

Clinical Otolaryngology, 1984
A review is given of the development of the concept of an artificial tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly-glycolic acid, poly-lactic acid and poly-alpha-amino acids.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
