Enlarged adenoids refers to swollen lymphatic tissue in the back of the nose. The tissue is similar to the tonsils.

Enlargement of the adenoids may occur naturally (beginning during fetal development), or it may be caused by long-term inflammation.

• Mouth breathing (mostly at night)
• Dry mouth
• Cracked lips
• Mouth open during day (more severe obstruction)
• Bad breath
• Persistent runny nose or nasal congestion
• Frequent ear infections
• Snoring
• Restlessness while sleeping
• Intermittent sleep apnea

The adenoids cannot be seen by looking in the mouth directly, but can be seen with a special mirror or using a flexible endoscope through the nose.

Tests may include:

• X-ray (side view of the throat)
• Sleep apnea studies (severe cases only)
