Objective: To assess the association between self-reported symptoms of pediatric OSA and clinical signs in MB children.
Methods: Seventy-three MB children aged 7-14 years answered an interview questionnaire on OSA symptoms in childhood, focusing on chewing, nasal, and sleep disturbances. MB children were checked for changes on the craniofacial, occlusion, TMJ, upper airway, and body posture by a multi-disciplinary team, consisting of medical residents, dental, and psychology postgraduate students. Multiple logistic regression analysis verified the association between clinical signs and self-reported symptoms.
Results: Reported symptoms of chewing disturbance as TMD noise, muscle pain, and morning headache were significantly associated with the presence of lip incompetence and Class II malocclusion. Sleep disturbances as snoring, waking up at night, daytime sleepiness, and sleeping with the mouth open were significantly associated with the presence of hypertrophic tonsils and obstructive Mallampati score.
Conclusion: Symptoms of pediatric OSA were found in mouth-breathing children, which should be carefully investigated in order to prevent OSA in the future.
