middle ear cavity

The move forces air through the Eustachian tube to the middle ear cavities.

In most cases, the ossicles and the middle ear cavity were dysmorphic.

Bone invasion and destruction are usually not seen in this tumor which expands within the mesotympanum (middle ear cavity).

The middle ear cavity has a complex of bony, air-filled passages and a branching eustachian tube.

The middle ear cavity of troodontids and ornithomimosaurs was enlarged, suggesting sensitivity to low-frequency sounds.

The ears of troodontids were also unusual among theropods, having extremely enlarged middle ear cavities, indicating acute hearing ability.

In most frogs and toads, it is similar to that of reptiles, but in other amphibians, the middle ear cavity is often absent.

Pressure regulation in the middle ear cavity of sea lions: a possible mechanism S Odend'hal, T C Poulter Science.

There is no eardrum and no earhole, and the middle ear cavity is filled with loose tissue, mostly adipose (fatty) tissue.

These proved to be Stenurus globicephalae, and they were also present in much greater numbers in the pterygoid air sinuses close to the middle ear cavity (see Figure).

While patients present with symptoms related to the middle ear cavity location of the tumor, the tumor may expand into the adjacent structures (external auditory canal, mastoid bone, and eustachian tube).

Also present are the inferior tympanic branch which ascends towards the middle ear cavity; it is involved in internal carotid artery reconstitution via the "aberrant carotid artery" variant.

At the base of the cochlea, each scala ends in a membranous portal that faces the middle ear cavity: The scala vestibuli ends at the oval window, where the footplate of the stapes sits.

The hearing loss is the result of ectopic ossification along the round window ridge at the outside of the cochlea, massive deposition of cholesterol crystals in the middle ear cavity, an enlarged Eustachian tube and a chronic otitis media with effusion.

A temporal bone CT using thin slices makes it possible to diagnose the degree of stenosis and atresia of the external auditory channel, the status of the middle ear cavity, the absent or dysplastic and rudimentary ossicles or the inner ear abnormalities such as a deficient cochlea.
