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 ...

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 ...

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 ...

Systemic corticosteroids for acute otitis media in children [PDF]
, 2018 Background: Acute otitis media (AOM) is a common acute infection in children. Pain is its most prominent and distressing symptom. Antibiotics are commonly prescribed for AOM, although they have only a modest effect in reducing pain at two to three days.

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 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

Doppler optical coherence tomography as a promising tool for detecting fluid in the human middle ear
Current Directions in Biomedical Engineering, 2016 The treatment of otitis media requires classifying the effusion in the tympanic cavity for choosing appropriate therapeutic strategies. Otoscopic examination of the middle ear depends on the expertise of the physician and is often hampered in case of ...
