Chest Masculinization Technique and Outcomes in 72 Double-incision Chest-contouring Procedures with Free Nipple Grafting.

UNLABELLED

Chest masculinization for gender affirmation is the removal of breast tissue and excess skin, often with repositioning of the nipple areola complexes to achieve a male-appearing chest. A double-incision technique with free nipple grafting (FNG) is the preferred method for trans men with large, ptotic breasts. The authors present the outcomes of 72 consecutive chest masculinization cases using this technique.

METHODS

A retrospective chart review was performed between 2015 and 2020 on all patients who underwent chest masculinization surgery for gender dysphoria by the senior author (JDK). Patients who underwent masculinization by concentric circle or liposuction-only techniques were excluded. Potential risk factors for complications were analyzed with Chi-square and logistic regression techniques. < 0.05 was considered significant.

RESULTS

Seventy-two patients underwent bilateral mastectomy with free nipple grafting. There were 6 major complications resulting in return to operating room, re-admission, or need for interventional procedure. These included 4 hematomas, 1 infection, and 1 hospital admission for shortness of breath and pain.Minor complications treated conservatively included 3 seromas, 1 instance of delayed wound healing, 1 case of superficial thrombophlebitis, and 4 hypertrophic scars. Eleven patients experienced nipple areolar complex complications. Four patients underwent revision surgery. Nicotine use was associated with a higher rate of hematoma (2: 9.95, = 0.007). Later operative date, a surrogate for experience, was associated with decreased return to the operating room (Odds ratio: 0.99, = 0.025).

CONCLUSION

Double-incision chest contouring with free nipple grafting provides good chest contour for transgender men,with low complication rates.
