Some tetrapods have, nonetheless, secondarily lost their tympanum and middle ear. One is example is the snakes that all have a reduced tympanic cavity and no tympanum or Eustachian tubes. Snakes have, ...

Light from the heat sink cavity was directed into the ear through the Welch ... Once adequate identification of the normal anatomic landmarks of the tympanic membrane and middle ear was established, ...

The middle ear cavity and auditory ossicle chain were examined. Any tympanosclerotic plaques and scar adhesions around the tympanic membrane, auditory ossicles, and anterior tympanic isthmus were ...

Initial results from one temporal bone study indicated that the actuator was small enough to be implanted within the middle ear cavity, and sufficient stapes displacement can be generated for patients ...

Swelling of the tympanic membrane can cause calcium deposits ... as linear or web-like forms of calcified masses in the middle ear cavity. Surgery is an option for treating damage to the eardrum ...

The inner ear contains distinct sensory organs, produced sequentially by segregation from a large sensory-competent domain in the developing otic vesicle. To understand the mechanistic basis of this ...

Researchers have found in a new study published in Laryngoscope that effective treatment of upper airway atopic diseases greatly enhances middle ear function by decreasing the necessity for pressure ...

"A single-dose treatment for middle ear infections represents a significant ... However, these infections occur behind the tympanic membrane (eardrum)—a structure that is impervious to most ...

For middle ear infections, applying an antibiotic directly to the infected area rather than taking it orally could help reduce side effects like yeast infections and upset stomach. However, these ...

In this paper, we investigate how various geometries of MEMS piezoelectric accelerometers, optimized via different optimization techniques, behave in terms of the equivalent input noise (EIN) in sound ...
