Few studies have considered the diverse mental and physical health impacts of scarring among transgender and gender diverse (TGD) patients after medically necessary gender-affirming surgery (GAS). For some TGD patients, post-GAS scarring may exacerbate gender dysphoria. For others, it is a physical representation of authenticity. The dearth of research or validated instruments capturing the diversity of priorities and concerns pre- and post-GAS hinders providers' ability to deliver optimal clinical care throughout the gender-affirmation process and impedes progress for evidence-based policy change regarding post-GAS scar treatment. This article provides suggestions for future research directions to address post-GAS scar-related health needs.
