To determine if monitoring weight growth curves is a sensitive objective parameter for evaluating operative outcomes after supraglottoplasty.Retrospective chart review.An IRB approved retrospective review of patients who underwent supraglottoplasty from 2/28/2012 to 10/20/2014 by the otolaryngology department at a single institution was performed. Variables collected included age, race, sex, preoperative weight percentiles, and weight percentiles at 3month, 12month, and 3year followup intervals.20 patients met inclusion criteria. 15 (75%) patients were male and 5 (25%) were female. 9 (45%) patients were African American, 8 (40%) were Caucasian, and 3 (15%) were other. Average weight for age at surgery was 29.8 percentile. 6 (30%) had failure to thrive by weight. By 3months postop average weight had increased by 7.67 percentile (p=0.09, 95% CI -1.62 to 17.0), by 12months there was an observed increase of 19.1 percentile (p=0.06, 95% CI 0.47-37.8), and by 3years the average weight had increased by 26.53 percentile (p=0.03, 95% CI 4.47-48.59). By three years postop the average weight had normalized (64.5 percentile). Among those who met preoperative failure to thrive criteria (average 0.11 percentile), weight gain was still dramatic with average weight percentile of 37.5 by 3years postop.Patients undergoing supraglottoplasty are typically underweight for age. Statistically significant weight gain occurs in children after going supraglottoplasty. This intervention can normalize their growth chart growth patterns by 3years postoperatively, even in children with failure to thrive.
