Long-Term Effects of Adenotonsillectomy on Growth and Symptoms in Childhood / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: This study was performed to evaluate the long-term effect of adenotonsillectomy on childhood growth by examining preoperative growth status and presenting symptoms. SUBJECTS AND METHOD: One hundred and four patients who underwent adenotonsillectomy from January to December 2009 were enrolled in this study. Clinical data were collected from medical record reviews and through the administered questionnaire. We investigated symptoms and growth changes during 5 years following the surgery. RESULTS: The mean age of patients was 6.0±1.94 years (range, 3–10), with the male to female ratio of 6242. Pre-operative symptoms were significantly improved after the surgery. The mean pre-operative height and weight percentiles were 53.6±27.4 and 59.6±29.2 at initial evaluation, and 67.1±26.4 and 59.6±28.6 at 5 years post adenotonsillectomy (p < 0.001, p=0.989), respectively. An increase in height percentile was more prominent in patients whose pre-operative height percentile was less than 50 compared to those with a percentile of 50 or more (p < 0.001). Weight percentile was significantly increased in those with the pre-operative weight percentile of less than 50 and decreased in patients with a percentile of 50 or more. CONCLUSION: Adenotonsillectomy has a positive effect on height growth in children with adenotonsillar hypertrophy, especially in patients whose height percentile is less than 50. Weight gain also can be expected in preoperative low-weight children.
