Objectives:
This study aimed to investigate the association between adenotonsillectomy (T&A) and serial changes in growth in children through a population-based nationwide study as well as the national health insurance service (NHIS) database.
Methods:
Propensity score (PS) matched children with and without T&A were selected in NHIS database, which includes all individuals born in Korea in 2008-2009. Serial changes of BMI and height were compared in children with and without T&A, and growth changes depending on the time of operation were also considered. The outcomes were differences in age-/sex-standardized BMI (BMI-z) and height (height-z) between the groups. Changes in BMI-z and height-z were further analyzed according to the timing of operation.
Results:
Of 919,707 individuals born in Korea in 2008-2009, 3172 children were included in the operation group and 31,663 PS-matched children were included in the control group. T&A was related to increased weight and height in the operation group than in the control group. At 66-71 months of age, BMI-z and height-z were 0.41 (0.02) and 0.42 (0.02), respectively, in the operation group and 0.18 (0.01) and 0.35 (0.01), respectively, in the control group. On adjustment with preoperative BMI-z, more weight gain was noted in the operation group (p < 0.001). Shortly after T&A, BMI-z increased significantly in the operation group; a significant increase in height-z was observed more than 1 year after T&A.
Conclusions:
Children who underwent T&A tended to experience a growth spurt; when surgical intervention such as T&A is required, care should be taken to minimize or reverse the anticipated weight gain.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
