Use of the Subfascial Plane for Gender-affirming Breast Augmentation: A Case Series

Abstract

Background:. Transgender women seeking gender-affirming breast augmentation often present with differences in preoperative chest measurements and contours in comparison with cisgender women. These include a more robust pectoralis muscle and limited glandular tissue, raising important considerations in determining the optimal anatomical plane for implantation. Abundant literature has described advantages and drawbacks of the available planes for breast augmentation in cisgender women. Certain drawbacks may be more pronounced for transgender women, given their distinct anatomy. The subfascial plane offers lower complication rates than the subglandular plane when using smooth implants, and avoids implant animation and displacement associated with the subpectoral plane. To our knowledge, existing studies have not yet addressed this discussion in the transfeminine population. The goal of this article is to highlight potential benefits of the subfascial plane for gender-affirming breast augmentation, utilizing a case series of 3 transfeminine patients, and to review the literature on surgical techniques and outcomes in this population. Methods:. A retrospective chart review of patients presenting to a single surgeon for gender-affirming breast augmentation in 2019 was performed. A narrative literature review on surgical techniques and outcomes for gender-affirming breast augmentation was conducted. Results:. Three cases of gender-affirming breast augmentation using subfascial implant placement are described. From the literature search, 12 articles inclusive of 802 transfeminine patients were identified. Conclusions:. The subfascial plane represents an option for implant placement in gender-affirming breast augmentation that merits further investigation. There is a need for more research comparing surgical techniques and outcomes in the transfeminine population.
