Trends in Top Surgery Patient Characteristics, Wound Complications, and CPT Code Use by Plastic Surgeons: A Decade-Long Analysis.

Background: Gender-affirming top surgery is becoming increasingly common, with greater diversity in the patients receiving top surgery. The purpose of this study was to examine national trends in patient demographics, characteristics, wound complication rates, and concurrent procedures in patients receiving gender-affirming top surgeries.

Methods: Patients with gender dysphoria who underwent breast procedures, including mastectomy, mastopexy, breast augmentation, or breast reduction by a plastic surgeon between 2013 and 2022, were identified from the American College of Surgeons National Surgical Quality Improvement Program database. These procedures were considered to be gender-affirming "top surgery." Univariate analyses were performed to examine trend changes in the patient population and types of additional procedures performed over the last decade.

Results: There was a 38-fold increase in the number of patients who received top surgery during the most recent years compared to the first 2 years of the decade. Significantly more individuals receiving top surgery in recent years were nonbinary ( P < 0.01). There was a significant decrease in percentage of active smokers ( P < 0.01) while there was an increase in percentage of patients with diabetes ( P = 0.03). While there was a significant increase in the number of obese patients receiving top surgery ( P < 0.01), there were no differences in postoperative wound complications between the years. Significantly more patients received additional procedures ( P < 0.01) and had about a 9-fold increase in distinct number of additional CPT codes from 2013-2014 to 2021-2022.

Conclusions: Our study found that there has been (1) a significant increase in the number of top surgery patients from 2013 to 2022 overall and (2) a particular increase in patients with preoperative comorbidities, such as a higher body mass index and diabetes. Understanding current and evolving trends in patients undergoing surgical treatment for gender dysphoria can inform individualized care plans that best serve the needs of patients and optimize overall outcomes.
