Eustachian Tube Dysfunction (ETD)
Normal middle ear function relies on normal eustachian tube function
The Eustachian Tube remains closed; opening when we chew, yawn or swallow. This keeps the air pressure equal on both sides of the eardrum.
The eardrum vibrates easily and you hear clearly.
What is ETD ?
If the Eustachian Tube does not open frequently, air cannot get into the middle ear.
The air pressure on either side of the eardrum becomes unequal
The eardrum may become retracted (sucked in). This makes the eardrum unable to vibrate well, making your hearing dull.
If this continues, fluid may form behind the ear drum, dulling your hearing and making you prone to glue ear and middle ear infection.
- Dulled hearing
- Feeling of fullness in the ear
- Ringing, buzzing, popping or crackling sounds
Symptoms can last from a few hours to several weeks or more.
- Large Adenoids
- Facial Abnormalities
- Lowered Immune System
Children are particularly prone to ETD as their Eustachian tubes are smaller, more horizontal than an adults and the surrounding cartilage, bone and muscle are still developing.
Improving Eustachian Tube Function

If you have a temperature or fever, swollen glands, increasing pain and feel increasingly unwell SEEK MEDICAL ATTENTION
The Eustachian Tube
Connects the middle ear to the back of the throat.
It has 3 functions:
- Allows air in and out of the middle ear
- Allows secretions to drain out
- Stops backflow of fluid from throat to middle ear
