D59. Role of Safety Limits to Tissue Resection Weight in Adolescent Reduction Mammaplasty

PURPOSE: Reduction mammaplasty (RM) is the gold-standard treatment for symptomatic macromastia. While associated with significant improvements to quality of life; complications rates related to wound healing are high, with obesity, smoking, and a tissue resection weight (TRW) ranging from >700 to >1500 g, among the reported risk factors. Adolescent patients (10 to 24 years old) make up a growing number of RM procedures in recent years, yet to our knowledge, the existing literature on TRW as a risk factor is predominantly measured from adult and middle-aged populations, with limited data that measures the risk in adolescents. METHODS: Retrospective chart review of all adolescent RM from 2014 to 2021. Odds Ratio was calculated using bivariate logistic regression for complication event with α set to 0.05.*Postoperative complications were measured between 1 week to 6 months after RM. RESULTS: 66 cases were analyzed with an average age of 18.8±3.4 years, with the youngest patient being 13 on the day of surgery. Univariate analysis revealed a significantly increased risk of complications in patients with a BMI ≥ 30;(P=0.002), BMI 30-34.9;(P=0.001), and BMI 35-39.9;(P=0.014). TRW per breast >1000 g, 1000-1500 g, and >1500 g was not significant for an increased risk of complications. CONCLUSION: In 66 consecutive adolescent RM’s, 43.9% of patients experienced complications related to wound healing; consistent with rates in the existing literature. In our study patients with BMI≥30 were found to have significant increased risk of wound complications. TRW did not have a significant effect on wound complications.
