Increasingly more nonbinary
patients are obtaining better access for gender-affirming chest surgery
(top surgery), representing an important subset of patients who undergo such surgery.
We review our experience at gender-affirming chest surgery
versus transmasculine patients in an integrated health care setting.
We performed a retrospective study of nonbinary
and transmasculine patients who underwent gender-affirming chest surgery
from May 1, 2012, to December 27, 2017.
There were 111 nonbinary
patients and 665 transmasculine patients included in the final analyses. Nonbinary
patients were more likely to seek more than 1 surgical consultations than transmasculine patients (24.3% vs 1.7%, respectively, P
< 0.0001). More nonbinary
patients (17.3%) indicated nipple sensation to be important relative to their transmasculine counterparts (0.4%, P
< 0.0001). Fewer nonbinary
patients were on testosterone before surgery (33.64%) in comparison to transmasculine patients (86.14%, P
< 0.0001). When only prior reduction mammaplasty or top surgery were considered, nonbinary
patients (8.1%) were more likely than transmasculine patients (3.5%) to have had a prior chest surgery. When evaluating patients who did not have prior chest surgery before undergoing top surgery at our institution (n = 721), rates of major complications, minor complications, as well as revisions, were comparable between nonbinary
and transmasculine patients.
This study demonstrated that more nonbinary
patients requested nonflat chests relative to their transmasculine counterparts. Both groups in our sample displayed comparable rates of complications after top surgery.
