The Eustachian tube is a small passageway that connects your throat to your middle ear. This keeps air pressure and fluid from building up inside your ear. But sometimes a Eustachian tube might get plugged.
The condition is multifactorial. In many cases, inflammation of the mucous membranes in and around the Eustachian tube produces obstruction. Uncoordinated movement of the muscles that open and close the tube may also play a role.

Inserting a small, balloon-like device in a blocked eustachian tube may bring lasting relief to the millions of children and adults who suffer from chronic eustachian tube dysfunction each year.
ETD occurs when there is a dysfunction of the Eustachian tube. This condition prevents the release of pressure and fluid from the middle space the space behind the tympanic membrane or ear drum. It can occur during common colds, upper respiratory tract infections, allergies, impeded nasal airflow or chronic drainage of mucus on the tube opening. The Eustachian Tube ET is a small passage way that connects the middle ear to the nasopharynx.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. This research study measures how well the Eustachian tube works and looks directly at the anatomy of the Eustachian tube in adults who have had tympanostomy tubes surgically inserted into their eardrums because they have been diagnosed as having either "otitis media" or "poor Eustachian tube function". The Eustachian tube is a biologic tube that connects the back of the nose to the middle ear the airspace located behind your eardrum.

Eustachian tube dysfunction ETD can cause dulled hearing and a feeling of pressure or fullness in the affected ear. It is usually just a temporary problem during and after a cold. There are various other causes and sometimes it lasts longer. Often no treatment is needed but decongestants, antihistamines or a steroid nasal spray sometimes help.
Eustachian tubes are small tubes that run between your middle ears and the upper throat. They are responsible for equalizing ear pressure and draining fluid from the middle ear, the part of the ear behind the eardrum. The eustachian tubes are usually closed except for when you chew, swallow, or yawn.
The ear is divided into three parts: the external ear includes the visible part of the ear the pinna and the ear canal; the middle ear is the air-filled space behind the eardrum that contains the three middle ear bones the ossicles ; and the inner ear contains the sensory organs of hearing cochlea and balance semicircular canals. The Eustachian tube is a narrow tube that connects the middle ear to the back of the nose. Normally, the Eustachian tube opens with every swallow or yawn to act as a pressure-equalizing valve for the middle ear. It also serves to drain the mucus produced by the lining of the middle ear.
