I appreciate your question. In my practice, I require transgender (and non-binary) clients who are considering a top surgery to have been on hormones for at least 18 months prior to their top surgery. The reason for this is that hormones alone may result in a decrease of breast tissue, increased body and facial hair, and other significant physical changes. Keep in mind, the decrease in estrogen will shrink your breasts, but ultimately you may still need surgery to achieve your desired results. The two major methods I use for FTM top surgery are double incision mastectomy with nipple grafting and keyhole. Keyhole (also known as peri-areolar) is ideal for small chested transgender men, up to a b-sized chest, with good skin elasticity. Double incision mastectomy procedure is ideal for medium to large chested transgender men. In both techniques, additional liposuction may be performed to adjust the contour of the chest. Which method we choose for your top surgery will depend on the size of your breasts. But, rest assured, no matter how much breast tissue there is to remove, there is a surgery for you. Our goal is to help you feel comfortable, happy, and confident in your own skin. The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery. best of luck!
