The sample size was calculated based on Pearson's correlation, adopting a significance level of 5%, test power of 80%, and an initial correlation between obstruction of the rhinopharynx by adenoid and clinical symptoms of 0.4 was assumed, resulting in a minimum sample of 50 patients.Intra-rater reliability (between T1 and T2) was established by Pearson's correlation, being considered high when Once the high intra-rater reliability was accepted, the mean response of the patient of each rater was used for the inter-rater reliability study, through the Intraclass Correlation Coefficient (ICC). It was adopted as a reliable ICC greater than 0.7.Pearson's correlation was used to study the relationship between: (1) Subjective measurement of rhinopharyngeal obstruction by the adenoid, and objective measurement, by Pro ImageJ Software; (2) Obstruction of the rhinopharynx by the adenoid, both subjectively and objectively, and the intensity of the clinical symptoms determined by the OSA-18.To explore the relationship between potential risk factors that could influence correlation between rhinopharyngeal obstruction by the adenoid and the impact on quality of life (OSA-18), Pearson's correlation was used for qualitative risk factors, and Student's
