Pediatric Sleep Apnea in Singapore

A common type in children, OSA occurs when throat muscles relax during sleep, causing physical blockage of the airway. Enlarged tonsils and adenoids are common causes in paediatric cases. Children with OSA may snore, experience breathing interruptions, and show signs of restless sleep with frequent position changes.

Less common in children, CSA happens when the brain does not send proper signals to the breathing muscles. This type may be associated with neurological conditions, prematurity, or certain medications. Children with CSA may not snore but can still experience breathing pauses and sleep disruption.

Also called mixed sleep apnoea, this combines features of both OSA and CSA. Children with complex sleep apnoea may experience both airway obstruction and irregular brain signalling. This type requires evaluation and may involve multi-disciplinary treatment approaches.

• Loud, persistent snoring occurring most nights
• Gasping, choking, or snorting sounds during sleep
• Observed breathing pauses lasting several seconds
• Restless sleep with frequent tossing and turning
• Bedwetting in previously toilet-trained children
• Night sweats unrelated to room temperature
• Teeth grinding (bruxism)

• Excessive daytime sleepiness despite adequate sleep time
• Morning headaches that improve as the day progresses
• Difficulty waking up, even after long sleep periods
• Mouth breathing during waking hours
• Chronic nasal congestion or voice changes
• Difficulty concentrating in school
• Behavioural problems, including hyperactivity or aggression
• Poor school performance or learning difficulties

• Poor weight gain or growth delays
• Failure to thrive in infants
• Delayed developmental milestones
• High blood pressure for age
• Enlarged heart on examination

These symptoms often develop gradually, and parents may attribute them to other causes. The combination of nighttime breathing difficulties with daytime behavioural or concentration problems may suggest that sleep apnoea evaluation could be considered.

For mild cases without significant daytime symptoms, careful monitoring may be considered. Regular follow-ups track symptom progression. This approach may suit children with mild snoring but no observed apnoeas or daytime impairment. Parents can maintain sleep diaries and monitor for symptom changes that may require active intervention.

Intranasal corticosteroid sprays may help reduce adenoid inflammation and improve nasal airflow. Treatment typically continues with regular reassessment. Leukotriene modifiers, such as montelukast, may help children with concurrent allergies. Antibiotics can treat underlying sinus infections contributing to symptoms. Weight management programmes may address obesity-related sleep apnoea through dietary counselling and increased physical activity.

CPAP therapy delivers pressurised air through a mask, keeping airways open during sleep. Modern paediatric CPAP machines feature child-friendly designs and adjustable pressure settings. Success requires proper mask fitting and gradual acclimatisation. Regular follow-ups help with appropriate pressure adjustments as children grow. CPAP can be effective but requires consistent use and family commitment.

Custom-fitted oral appliances can help reposition the jaw and tongue to maintain airway patency. Rapid maxillary expansion devices may widen the upper jaw in growing children. These treatments may work for mild to moderate cases with specific anatomical features. Regular orthodontic monitoring helps in proper fit and effectiveness as children develop.

Surgical removal of enlarged tonsils and adenoids is a treatment option for children with obstructive sleep apnoea. This outpatient procedure is performed under general anaesthesia. Recovery typically requires pain management and a soft diet. This procedure may be suitable for children with adenotonsillar hypertrophy.

Uvulopalatopharyngoplasty (UPPP) may reshape throat tissue in selected older children. Tongue reduction procedures can address macroglossia in specific syndromes. Maxillomandibular advancement surgery may correct jaw abnormalities in adolescents with completed growth. These procedures require evaluation and multi-disciplinary planning.

Specialised exercises may help strengthen tongue and throat muscles, potentially improving airway tone. Therapy sessions teach proper tongue positioning and breathing techniques. Children practice exercises daily. This non-invasive approach may complement other treatments and could help prevent recurrence after surgery.

While not all cases are preventable, several strategies may help reduce paediatric sleep apnoea risk. Maintaining a healthy weight through balanced nutrition and regular physical activity may help prevent obesity-related airway obstruction. Creating a smoke-free environment can help protect developing airways from irritation and inflammation.

Managing allergies with appropriate medications may help reduce nasal congestion and adenoid enlargement. Promoting nasal breathing through the treatment of chronic rhinitis may help support normal facial development. Breastfeeding during infancy may support oral and facial muscle development. Regular dental check-ups can help identify signs of jaw abnormalities that may require orthodontic intervention.

Establishing consistent sleep schedules aims to confirm that there is adequate rest. Teaching children proper sleep positioning and avoiding sedating medications unless medically necessary may help maintain airway patency. Treatment of enlarged tonsils and adenoids may help prevent progression to obstruction.
