Snoring in Children and Adenoids
The adenoids are lymphoid tissue behind the nose that form part of a child's immune system. They enlarge naturally between ages 3 and 7 and usually shrink towards adolescence without causing trouble. In some children, however, they grow large enough to block the nasopharynx and cause a cascade of problems.
Signs of enlarged adenoids
- Constant open-mouth sleeping and snoring
- Pauses in breathing during sleep, restless sleep, sweating
- Nasal blockage and persistent runny nose
- Recurrent middle ear infections or fluid (reduced hearing)
- Recurrent sinusitis, postnasal drip, night cough
- Daytime tiredness, attention problems, declining school performance
Is snoring normal in a child?
Occasional snoring during a cold can be acceptable. But regular snoring (more than 3 nights a week) — especially with witnessed pauses, gasping or choking arousals — must be evaluated for sleep apnea. Childhood sleep apnea is linked to growth delay, behavioural problems, hyperactivity-like pictures and strain on the heart.
"Adenoid facies"
Prolonged mouth breathing can alter facial growth: a long narrow face, high-arched palate, dental misalignment and a dull expression. Timely treatment of obstructive adenoids helps prevent these changes from becoming established.
Diagnosis and treatment
Diagnosis is made by examination and, when needed, a small flexible camera passed through the nose. Mild cases may be managed with nasal sprays and treatment of accompanying allergy. Adenoidectomy is recommended for:
- Sleep apnea or significant snoring and open-mouth sleeping
- Middle ear fluid / recurrent otitis with adenoid enlargement (often combined with ear tubes)
- Recurrent sinus and nasopharyngeal infections
The operation is performed through the mouth under brief general anaesthesia; there is no external scar and children usually go home the same day. There is no evidence that adenoid removal weakens immunity.
Frequently Asked Questions
What are the signs of enlarged adenoids in a child?
The most typical signs are constant open-mouth sleeping, snoring and nasal blockage with a persistent runny nose. Recurrent middle ear infections or fluid, sinusitis, postnasal drip and a night cough may also occur, along with daytime tiredness, attention problems and declining school performance.

What is adenoid facies?
Prolonged mouth breathing can alter a child's facial growth, leading to a long narrow face, high-arched palate, dental misalignment and a dull expression. Timely treatment of obstructive adenoids helps prevent these changes from becoming established.
When is adenoid surgery recommended for a child?
Adenoidectomy is generally recommended for sleep apnea or significant snoring with open-mouth sleeping, for middle ear fluid or recurrent otitis with adenoid enlargement, and for recurrent sinus and nasopharyngeal infections. Mild cases may first be managed with nasal sprays and treatment of any accompanying allergy.
Does removing the adenoids weaken a child's immune system?
No, there is no evidence that adenoid removal weakens immunity. The operation is done through the mouth under brief general anaesthesia, leaves no external scar, and children usually go home the same day.
