01 Oct Paediatric ENT in Singapore: When Your Child’s Snoring, Mouth Breathing, and Recurring Ear Infections Need Assessment
Health Information Notice: This article provides general information only and is not specific medical advice for any child. Healthcare providers and practices mentioned or linked in this article are not warranted or endorsed by MedicalResearch.com or Eminent Domains Inc. Seek urgent medical care if a child has difficulty breathing, long pauses in breathing during sleep with colour changes, a high fever with severe ear pain, swelling or redness behind the ear, or appears very unwell.
An occasional snore during a cold or an isolated ear infection does not necessarily point to an ongoing ENT problem. But if your child snores regularly, breathes through their mouth even when they are not unwell, or keeps getting ear infections, it may be time to look at what is causing the pattern.
These are some of the symptoms a paediatric ENT in Singapore may assess, particularly when they keep returning or start affecting sleep, hearing or speech.
Snoring and Mouth Breathing: When They Persist
Occasional snoring during a cold is common. Snoring that happens most nights, especially when paired with mouth breathing during the day, may point to an ongoing nasal or upper-airway cause or obstruction.
In children, enlarged tonsils and adenoids are the most common cause of snoring and obstructive sleep apnoea (OSA). The adenoids sit at the back of the nasal passage, and when enlarged, they can narrow the airway during sleep.
OSA involves repeated upper-airway obstruction during sleep. Not every child who snores has OSA. SingHealth estimates that three to 12 per cent of children have habitual snoring, while one to three per cent have snoring with OSA.
A child’s symptoms and physical examination alone may not reliably distinguish primary snoring, where breathing and sleep are not disrupted, from OSA. A sleep study may therefore be recommended if OSA is suspected.
What parents may notice:
- Snoring most nights, not just during colds
- Mouth breathing during the day, even without a blocked nose
- Restless sleep, frequent waking, or unusual sleeping positions
- Daytime irritability, poor concentration, or slower-than-expected growth
A Singapore Medical Journal review notes that paediatric OSA can have developmental and cognitive consequences.
Recurring Ear Infections and Middle-Ear Fluid
If your child has repeated ear infections, one factor an ENT may check is how well the Eustachian tube is ventilating and draining the middle ear.
The Eustachian tube regulates pressure and drainage in the middle ear. In young children, this tube is shorter and more horizontal than in adults, making fluid buildup more likely. When the tube does not drain properly, fluid can accumulate behind the eardrum.
Fluid may also remain after an infection has cleared. Persistent middle-ear fluid can affect hearing. Current clinical guidance recommends a hearing evaluation when middle-ear fluid has been present for three months or longer.
What you may notice between infections:
- Ear infections that keep returning
- Fluid or muffled hearing that lingers between infections
- A child who consistently favours one ear, or speaks louder than usual
- Delayed response to sounds or slower speech development
What Happens During a Paediatric ENT Evaluation
A paediatric ENT assessment usually starts with questions about how often symptoms occur, how long they have been present, and whether they affect sleep, feeding, or speech. This is followed by a physical examination of the ears, nose and throat.
For nasal and airway concerns, a paediatric ENT specialist may use nasendoscopy, a thin, flexible scope that allows direct visualisation of the adenoids and nasal passages. Whether this is needed depends on the child’s symptoms and examination findings.
Hearing assessments and, in some cases, a sleep study may also be recommended depending on the symptoms described.
A few practical points:
- Snoring during a cold does not by itself mean your child has OSA
- Mouth breathing does not always mean the adenoids are enlarged. Allergies and nasal congestion can cause similar symptoms
When to Seek an ENT Assessment
An ENT assessment may be appropriate when the same problems keep returning or begin to affect your child’s sleep, hearing, or speech.
Situations to discuss with a doctor include:
- Snoring most nights, especially with breathing pauses, gasping, or daytime symptoms
- Mouth breathing that continues outside of cold or flu episodes
- Three or more separate acute middle-ear infections in six months, or four within 12 months
- Any noticeable delay in speech or hearing response
An assessment does not automatically mean your child will need treatment. The next step may be monitoring, further tests or treatment, depending on the cause, how persistent the symptoms are and whether hearing, sleep or development is affected.
If the Same Symptoms Keep Returning
Children do not always have the words to explain that their hearing feels different or that they are not sleeping well. Parents may first notice regular snoring, persistent mouth breathing or ear infections that keep returning.
If you keep seeing the same pattern, an ENT assessment can help establish what is causing it and whether your child needs monitoring, further tests or treatment. For persistent or recurring ear, nose, throat and sleep-related concerns, Dr Dennis Chua, an ENT specialist in Singapore, sees both children and adults at ENT Surgeons Medical Centre.
All medical procedures carry potential risks and limitations, which should be discussed during a consultation.
