Abstract
SUMMARY: Gender-affirming mastectomy has become a highly sought-after procedure for the treatment of gender dysphoria and has been shown to improve quality of life in transgender and gender-nonbinary individuals. Aesthetic outcomes after double-incision mastectomy can be influenced by several factors; however, certain operative variables can be controlled to obtain aesthetic and reproducible results. Chest wall contour is arguably the most critical component of these procedures and requires highlighting the definition of the pectoralis muscle. Planning incisions within the inferior and lateral borders of the pectoralis major rather than the inframammary fold, and ensuring removal of all breast tissue in the lateral and medial chest and the axillary tail, will help obtain an aesthetically pleasing chest wall shape while concealing scars. Finally, attention to nipple resizing and repositioning inferiorly and laterally relative to the borders of the pectoralis muscle are critical to an aesthetic outcome. The authors have found that appropriate preoperative planning to control these three factors-(1) contour, (2) nipple position, and (3) scars-and critical analysis and adjustment of on-table results will help achieve the goals of creating an aesthetic and gender-congruent chest.
