What do ear tubes do?
The eustachian tube equalizes the air pressure in your middle ear. The middle ear is an enclosed area; air within it is usually sequestered; this is why changes in external pressure will cause some discomfort. The tubes go from the middle ear to the nasopharynx on either side. The tube is usually closed, but can open from time to time to complete its function.It also helps drain any fluids that may accumulate in there to help prevent possible ear infections.(If the middle ear didn't have a path to the outside, then the partial pressure of the gasses in venous blood would suck the air out of the space.)A tube leading from the tympanic cavity (middle ear) to the nasopharynx (region where nose meets mouth); it consists of an osseous (bony) (posterolateral) portion at the tympanic end, and a fibrocartilaginous (muscular) anteromedial portion at the pharyngeal end; where the two portions join, in the region of the sphenopetrosal fissure, is the narrowest portion of the tube (isthmus); the auditory tube enables equalization of pressure within the tympanic cavity with ambient air pressure, referred to commonly as "popping of the ears."its also called guttural duct, otosalpinx, tuba acustica, tuba auditiva, tuba auditoria, tuba eustachiana, auditory tube, eustachian tube and otopharyngeal tube.The Eustacian tube allows the ear to regulate the air pressure inside it.The eustachian tubes join the nasopharynx to the middle ear. They play a part in pressure equalization and mucous drainage.
