Results: Among the patients evaluated, 57.9% were male, in the age range of 5 to 10 years (57.4%), followed by 3 to 4 years (21.5%). In relation to the observed manifestations, snoring (84.6%), restless sleep (75.4%), irritability (65.1%) and apnea (60.5%) were the most prevalent, besides being present in almost half of patients (46.7%) of comorbidities such as allergic rhinitis and asthma. Conclusion: The male gender and the age range between 5 and 10 years are important factors in the suspicion of ORS-related symptoms. The snoring as a more frequent symptom during sleep, demonstrating the occurrence of oral breathing in these patients, serves as an alert for those responsible and health professional in the investigation and consequent early diagnosis of ORS.
