Ear Anatomy

The ear consists of external, middle, and inner structures. The eardrum and the three tiny bones conduct sound from the eardrum to the cochlea.

Medical Findings Based on Ear Anatomy

The external structures of the ear may aid in diagnosing some conditions by the presence or absence of normal landmarks and abnormal features including: earlobe creases, preauricular pits, and preauricular tags.

Middle Ear Infection (Otitis Media)
|
Otitis media is an inflammation and/or infection of the middle ear. Acute otitis media (acute ear infection) occurs when there is bacterial or viral infection of the fluid of the middle ear, which causes production of fluid or pus. Chronic otitis media occurs when the eustachian tube becomes blocked repeatedly due to allergies, multiple infections, ear trauma, or swelling of the adenoids.
