How do we recognize the child with OSAS?

Area of Science:

• Pediatric Pulmonology
• Sleep Medicine
• Otolaryngology

Background:

• Obstructive sleep-disordered breathing (SDB) encompasses primary snoring to obstructive sleep apnea syndrome (OSAS) in children.
• Clinical suspicion for OSAS arises from parental reports of symptoms and physical exam findings indicating upper airway obstruction.
• Symptoms include snoring, apneic events, daytime sleepiness, hyperactivity, poor school performance, growth issues, and enuresis.

Purpose of the Study:

• To review the clinical spectrum, diagnosis, and management of obstructive sleep-disordered breathing in children.
• To highlight risk factors and diagnostic challenges, particularly in resource-limited settings.

Main Methods:

• Review of clinical presentations, risk factors, and diagnostic modalities for childhood OSAS.
• Discussion of polysomnography as the gold standard, with alternatives like nocturnal oximetry and sleep questionnaires.
• Inclusion of upper airway endoscopy and MRI for identifying obstruction levels.

Main Results:

• Childhood OSAS has diverse symptoms and risk factors, including prematurity, family history, obesity, and African American ethnicity.
• Polysomnography is definitive but not always feasible; oximetry and questionnaires serve as screening tools.
• Endoscopy and MRI aid in localizing airway obstruction in complex cases.

Conclusions:

• Childhood OSAS is a spectrum of SDB with significant clinical manifestations and morbidities.
• Accurate diagnosis requires considering clinical suspicion, risk factors, and available diagnostic tools, adapting to resource availability.
• Further investigation with imaging may be necessary for complex cases to guide treatment.
