Hockey stick incision: a modified technique for chest wall masculinization

Chest wall masculinization is often performed for transgender men in order to address gender dysphoria. Peri-areolar and double-incision mastectomy with free nipple grafts, are the most common techniques employed in chest masculinization surgery, but are limited by their relative inconsistency and inefficiency in reconstructing a natural anterior contour that comprehensively resembles that of a cis-masculine chest. The purpose of this study is two-fold. The first is to describe the "hockey stick" approach, which expands on the widely performed double-incision mastectomy to the axilla, with an additional step of revising lateral chest wall folds of tissue excess. This technique is scalable to the degree of pre-operative excess tissue on the anterior and lateral chest wall. The second is to compare the "hockey stick" incision to existing reconstructive options, with respect to clinical outcomes and patient satisfaction.

Patients who received chest masculinization surgery at Yale-New Haven Hospital were included. A retrospective chart review, comprising demographic variables, procedural details, and post-operative events, was conducted. Selected modules from a validated survey instrument, the BODY-Q, were measured. Patients were classified by body mass index and incision, which included peri-areolar, inframammary fold, and "hockey stick" incision by date.

Twenty-seven of 73 (37.0%) participants completed the full survey and were included in the analysis. The "hockey stick" incision had comparable patient satisfaction and post-operative outcomes, compared to peri-areolar and double-incision mastectomy with free nipple graft techniques. Greater BMI patients had a higher incidence of wound dehiscence, compared to other weight classifications.

The "hockey stick" incision is a readily performed, effective surgical technique for building a cis-masculine appearing chest in transgender men with efficient and predictable outcomes. While performed in patients with higher BMI, the "hockey stick" confers equivalent patient satisfaction and clinical outcomes to peri-areolar and double-incision mastectomy.
