    IntroductionObstructive sleep apnoea-hypopnea syndrome (OSAHS) is characterised by recurring episodes of complete or partial upper airway collapse during sleep. Persistent OSAHS is associated with long-term consequences, such as growth failure, cardiovascular and neurocognitive problems in children. Different from the aetiology of OSAHS in adults, the most common cause of paediatric OSAHS is adenotonsillar hypertrophy. Adenotonsillectomy (AT) has been recommended as the first-line treatment of paediatric OSAHS. Several studies have suggested that retarded growth caused by OSAHS can improve after AT during the prepubertal period. This review will systematically search and summarise the available evidence on the effects of AT on children's growth.Methods And AnalysisWe will conduct electronic searches in MEDLINE (via PubMed), Embase, Google Scholar and the Cochrane Central Register of Controlled Trials for randomised controlled trials (RCTs) or cohort studies that included a control group. Additional records will be searched by checking the references included in the selected studies and relevant reviews. At least two authors will undertake selection of studies and data extraction independently and in duplicate. The Cochrane Risk of Bias tool and Risk Of Bias In Non-randomised Studies-of Interventions will be used to assess the risk of bias of RCT and cohort studies, respectively. A random-effects model will be used for meta-analyses. Data synthesis and other analyses will be carried out using the RevMan V.5.3 software. The Grades of Recommendation, Assessment, Development and Evaluation will be used to assess the quality of the supporting evidence behind each main comparison.Ethics And DisseminationThere is no ethical issue in this systematic review given that we will only include published studies. The results will be disseminated via peer-reviewed publications and social networks.Prospero Registration NumberCRD42019125882.© Author(s) (or their employer(s)) 2019.
