| Close to the front opening of the Eustachian tubes are masses of tissue called adenoids. |
| Enlarged adenoids can also be caused by repeated chest infections or allergies, but in other cases the cause is unknown. |
| The child was also mouth-breathing, a sign that her adenoids were so enlarged that she was unable to breathe through her nose. |
| Increased size of the adenoids causes breathing problems and also susceptibility to infections. |
| Even though some children may need surgery, it's important to remember that enlarged adenoids are normal in some children. |
| Enlarged adenoids or tonsils, which are at the back of the throat, may block the Eustachian tube. |
