What are adenoids and why do they enlarge?
Adenoids are lymphoid tissue located behind the nose. In some children they can enlarge due to recurrent infections, allergies, or anatomical factors.
Enlargement is not automatically “a disease”. The key is whether symptoms affect sleep, breathing, hearing, or daily functioning.
Sleep quality, breathing, and growth
- Nasal blockage → mouth breathing at night → fragmented sleep.
- Snoring; in some cases, sleep-disordered breathing may be present.
- Poor sleep can contribute to daytime fatigue and, in some children, may be associated with growth/weight gain concerns.
Hearing and ear infections (fluid behind the eardrum)
- Adenoid enlargement can contribute to Eustachian tube dysfunction → middle-ear fluid (otitis media with effusion).
- Temporary conductive hearing loss can affect speech and language development if it persists.
- Recurrent ear infections warrant structured evaluation.
Attention, behavior, and school performance
- Chronic poor sleep may show up as inattention, irritability, or hyperactivity-like symptoms.
- Morning fatigue and reduced concentration can impact learning.
- Addressing the underlying cause may improve quality of life in selected cases.
Long-term mouth breathing considerations
- Persistent mouth breathing may be associated with dry mouth and dental/bite issues in some children.
- There is rarely a single cause; assessment may include nasal factors, allergies, and dental evaluation when relevant.
When to see an ENT specialist
- Persistent snoring, restless sleep, or suspected breathing pauses.
- Chronic mouth breathing or long-standing nasal obstruction.
- Middle-ear fluid/hearing concerns or recurrent ear infections.
- Daytime fatigue and attention concerns together with night-time breathing symptoms.
How evaluation is done
- Medical history + ENT examination.
- Ear and hearing evaluation when indicated (audiology/tympanometry).
- Nasal endoscopy (when appropriate) to assess adenoid size.
- Allergy/nasal assessment based on symptoms.
Treatment options (depending on the case)
- Watchful waiting for mild cases with limited impact.
- Targeted medical therapy (e.g., nasal sprays when appropriate, prescribed by a physician).
- If symptoms are significant or complications exist: surgery (adenoidectomy) and/or ear procedures may be discussed after evaluation.
FAQ
Does every child with enlarged adenoids need surgery?
No. The decision is based on symptoms (sleep/hearing/infections) and evaluation findings.
Is snoring alone enough to decide?
Snoring is an important sign, but we also evaluate breathing during sleep and rule out other causes of nasal obstruction.
Can it affect speech and language?
If middle-ear fluid causes persistent hearing reduction, it may affect language development—hence structured hearing follow-up is important.
When is urgent evaluation needed?
If there are clear breathing pauses during sleep, severe breathing difficulty, or marked hearing loss symptoms.
