Introduction:
This systematic review investigates the influence of adenotonsillectomy (AT) on asthma control in pediatric patients.

Material and methods:
A literature review from 2000 to 2023 based on the databases PubMed, the Cochrane Library, and Web of Science. The analysis is distilled down to four studies that revealed positive outcomes in asthma control as gauged by the Asthma Control Test (ACT), the Childhood Asthma Control Test (C-ACT), clinical outcomes, and asthma-related chitinase levels.

Results:
The four studies consistently demonstrated improved asthma control postoperatively in terms of improved ACT scores, reductions in acute asthma exacerbations, emergency room visits, hospitalisations, and medication usage. Notably, the correlation between improved asthma control and decreased chitinase activity suggests that AT has an impact on molecular markers associated with asthma.

Conclusions:
The findings underline the potential benefits of AT in pediatric asthma management. However, the limitations of this study include a small number of studies and potential biases related to asthma’s natural course and seasonal variations. While the review provides evidence for the positive impact of AT on asthma control, further research with longer follow-up periods, case-matched controls, and consideration of seasonal factors is recommended.
