Facts about Eustachian Tube Function
- 05
Opening of the Eustachian tube is controlled primarily by the tensor veli palatini muscle, which contracts during swallowing.
- 04
A normally functioning Eustachian tube remains closed at rest and opens briefly during swallowing, yawning, or chewing to equalize pressure.
- 03
Dysfunctional Eustachian tube ventilation is a leading cause of otitis media with effusion, commonly known as glue ear, especially in young children.
- 02
Mucus drainage from the middle ear is a secondary function of the Eustachian tube, helping prevent fluid buildup that can cause infections.
- 01
The Eustachian tube connects the middle ear to the nasopharynx, equalizing air pressure on both sides of the eardrum.
