Both surgical treatment and non-surgical treatment are suggested by clinicians for children with habitual snoring related to adenotonsillar hypertrophy; However, how should the decision be made remains unclear. The objective of this study was to investigate potential predictors for the treatment decision, i.e., surgical treatment vs wait and see in children with habitual snoring related to adenoidal and/or tonsillar hypertrophy. Children with complaints of snoring and/or apnea associated with adenotonsillar hypertrophy who received polysomnography (PSG) monitoring at our Hospital were recruited. After at least 6 months, the subjects were followed up and grouped according to whether or not they had received adenoidectomy and/or tonsillectomy (AT) execution. The heights, weights, as well as the quality of life (assessed using the obstructive sleep apnea-18 (OSA-18) quality of life questionnaire) and baseline PSG of the subjects were recorded and compared. Two logistic regressions were performed to reveal the factors influencing decision-making on conducting AT. A total of 509 children were finally included (345 males and 164 females). Among these children, 287 eventually received AT. Significant differences in age, scores for item 1 and 5 of the OSA-18, apnea-hypopnea index, obstructive apnea index, obstructive apnea-hypopnea index (OAHI), and Lowest arterial oxygen saturation (P < 0.05) were observed between groups. By multivariate logistic regression, the factors that influenced the surgical decision were identified as follows: age < 7 years (P = 0.008: odds ratio [OR] = 1.667, 95% confidence interval [CI] 1.140-2.438), score for item 5 of OSA-18 > 4 points (P = 0.042: OR = 1.489, 95% CI 1.014-2.212) and OAHI > 1/h (P = 0.044: OR = 1.579, 95% CI 1.013-2.463). School-age children aged < 7 years, with OAHI > 1/h and mouth breathing scored > 4 points were more likely to receive AT during the disease process and thus require increased attention.
