A Three-Step Technique for Optimal Nipple Position in Transgender Chest Masculinization.

Abstract

The ideal position of the nipple-areola complex (NAC) in the transgender population can be a challenge to determine. The authors sought to determine the best location and aesthetics of the female to male NAC. Patients who underwent female to male mastectomy with free nipple grafting were included. NAC position is confirmed utilizing a vertical coordinate at the level of the 4th rib near the border of the pectoralis muscle and a horizontal coordinate determined by dividing each unilateral chest into vertical thirds from midline to anterior axillary line laterally. The NAC position is confirmed at the junction of the middle and lateral third. Symmetry is ensured bilaterally by creating a triangle and transposing it side to side; the base lies from sternal notch to inframammary fold in the midline and the apex is adjusted to the NAC. A 24-question survey utilizing a 5-point Likert scale was distributed postoperatively to assess the patient's thoughts about their chest, nipples, scar, and overall experience with the gender affirmation process. Thirty-one patients were included in this study. Eighteen patients responded to the postmastectomy survey, all of whom were highly satisfied with the aesthetic result postoperatively. All patients felt comfortable with their exposed chest. Nipple location was particularly highly received with 100% satisfaction rate (mean Likert score, 4.72). Nipple size and shape received a mean Likert score of 4.17 and 3.89, respectively. The triple confirmation technique is an easy, reproducible method to guide the surgeon in relocation of the NAC.
