Surgical Technique Selection in the Management of Pediatric Gynecomastia.

Introduction: Although the majority of pubertal onset gynecomastia is self-resolving in nature, persistent deformity may require surgical intervention. This study aims to identify patient factors associated with surgical technique selection and proposes an algorithm for the surgical management of pediatric gynecomastia.

Methods: A retrospective analysis was performed of all surgically managed pediatric gynecomastia patients operated on at a single institution from 2012 to 2022. Charts and patient photos were analyzed for patient and operative demographics, endocrinologic comorbidities, complications, and outcomes. Data were analyzed using bivariate and logistic regression analysis.

Results: Fifty-six surgically managed gynecomastia patients less than 18 years of age were included. The average age at surgery was 16.1 years old, with a mean BMI of 26.9. Most patients were overweight or obese (54.8%) and had Simon grade IIb or greater gynecomastia (55.4%) at presentation. All patients underwent 1 of 4 mastectomy techniques with or without liposuction: inferior periareolar (n=25, 44.6%), circumareolar (n=13, 23.1%), transverse with pedicled nipple (n=4, 7.1%), or free nipple graft (n=14, 25.0%). Bivariate and logistic regression analysis revealed significant differences in sternal notch-to-nipple distance, nipple-to-inframammary fold distance, breast resection weight, and gynecomastia grade between the 4 surgical techniques used in this study. An algorithm incorporating these factors was devised to guide surgical decision-making.

Conclusions: The proposed algorithm guides surgical technique selection for pediatric gynecomastia and is contingent upon the degree of ptosis and skin excess, anticipated resection weight, and skin quality.
