The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
Narrow ear canals, curvy ear canals, and aging increase the likelihood of earwax build-up. One study from Fairey et al. in 1985 shows that low earwax production increases infection risk. Rare ...
The ear is designed to be self-cleaning, but some people are more prone to earwax buildup due to their ear canal shape. For example, very curvy ear canals, narrow ear canals, or surgical ears are ...
Surfer's ear is the common name for an exostosis or abnormal bone growth within the ear canal.

[1] Surfer's ear is not the same as swimmer's ear, although infection can result as a side ...
The iter chordæ posterius (apertura tympanica canaliculi chordæ) is situated in the angle of junction between the mastoid and membranous wall of tympanic cavity immediately behind the tympanic membrane and on a level with the upper end of the manubrium of the malleus; it leads into a minute canal, which descends in front of the canal for the ...
Exostoses, abnormal growth of bone within the ear canal; Tumor of the ear canal; Congenital stenosis or atresia of the external auditory canal (narrow or blocked ear canal). Ear canal stenosis & atresia can exist independently or may result from congenital malformations of the auricle such as microtia or anotia. Acquired stenosis (narrowing) of ...
The initial medical intervention is aimed at assessing the baby's hearing and the condition of the ear canal, as well as the middle and inner ear. Depending on the results of tests, reconstruction of the outer ear is done in stages, with planning for any possible repairs of the rest of the ear. [30] [31] [32]
