Top surgery refers to chest procedures that reshape the chest to match a person’s gender identity. For transmasculine patients, this means removing breast tissue to create a flat or more masculine chest contour. For transfeminine patients, it means breast augmentation with implants. The specific technique your surgeon uses depends on your chest size, skin elasticity, and aesthetic goals.
Masculinizing Top Surgery Techniques
There are several surgical approaches for creating a flatter chest, and the right one depends largely on how much tissue needs to be removed and how well your skin can bounce back afterward.
Double Incision
This is the most common technique, designed for people with medium to large chests and lower skin elasticity. The surgeon makes two horizontal incisions, typically along the lower border of the chest muscles. Through these incisions, they remove breast tissue, excess skin, and fat. Because so much tissue is removed, the nipples usually can’t stay attached to their blood supply during surgery. Instead, the surgeon removes the nipple-areolar complex entirely, resizes it to a smaller, more typically masculine proportion, and grafts it back onto the chest in a new position. This is called a free nipple graft.
The trade-off with this approach is scarring and sensation. You’ll have two visible horizontal scars across the chest (which fade over time but don’t disappear), and because the nipples are fully detached and reattached, most people lose significant nipple sensation. The nerves that supply feeling grow back at roughly one millimeter per day, so recovery of any sensation can take up to a year, and full return isn’t guaranteed.
Keyhole and Periareolar
These less invasive options work for people with small chests and good skin elasticity. In the keyhole technique, the surgeon makes a small incision along the lower edge of the areola and removes breast tissue through that opening, sometimes with the help of liposuction. The periareolar approach uses a circular incision around the entire areola, allowing the surgeon to remove a ring of skin along with the underlying tissue. Both methods leave the nipple attached to its blood supply the entire time, which preserves more sensation and avoids the need for a graft. Scarring is also minimal, limited to the edge of the areola. The catch is that these techniques can only handle a limited amount of tissue removal, so they aren’t an option for most people.
What Happens During Surgery
Top surgery is performed under general anesthesia, meaning you’re fully asleep. The procedure typically takes two to four hours depending on the technique. After the surgeon removes tissue and reshapes the chest, the incisions are closed with dissolvable stitches or stitches that get removed at a follow-up visit. One or two small plastic drainage tubes are placed under the skin at the surgical site. These tubes connect to soft bulbs that collect fluid as your body heals. You’ll go home with these drains in place and need to empty and measure the fluid output a few times a day until your surgeon removes them, usually within the first one to two weeks.
Feminizing Top Surgery Techniques
For transfeminine patients, top surgery means breast augmentation using implants. The key decision is where the implant sits relative to the chest muscle.
Submuscular placement positions the implant beneath the chest muscle. This tends to create a more naturally contoured shape and reduces the chance of visible rippling along the implant edges. The downside is that chest muscle contractions can temporarily distort the implant shape, and the space between the breasts may appear wider.
Subglandular placement puts the implant above the muscle, directly behind any existing breast tissue. When there’s enough tissue to cover the implant, this can look very natural and move with the body. However, there’s a higher risk of visible rippling and a complication called capsular contracture, where scar tissue tightens around the implant. A third option, subfascial placement, positions the implant beneath a thin layer of connective tissue that covers the muscle. This approach has a capsular contracture rate of about 1% and works particularly well for patients who are slim or athletic, since the fascia helps smooth out the implant edges.
Eligibility and Preparation
Current guidelines from the World Professional Association for Transgender Health require one referral from a qualified health professional for masculinizing chest surgery. Hormone therapy is not a prerequisite, meaning you don’t need to be on testosterone before having the procedure.
Preparation starts weeks before your surgery date. If you smoke or use nicotine products, you’ll need to stop at least four to six weeks beforehand. Quitting during that window and staying nicotine-free for four weeks after surgery cuts wound complication rates by 50%, according to the American College of Surgeons. Nicotine constricts blood vessels, which starves healing tissue of oxygen. This is especially critical if you’re having a free nipple graft, where the grafted tissue depends entirely on new blood supply to survive. Your surgeon will also ask you to stop certain supplements and medications that thin the blood.
Recovery Timeline
The first week is the hardest. You’ll have compression bandages or a surgical vest around your chest, drainage tubes still in place, and limited arm mobility. Most people need someone to help them with basic tasks like cooking and getting dressed during this period. Pain is typically managed with prescribed medication and transitions to over-the-counter options within the first week or two.
After the drains come out (usually by week two), movement gets easier but restrictions remain. For the first few weeks, you should avoid lifting anything heavier than five pounds. Light cardio, like walking or gentle cycling, can resume around three weeks as long as you aren’t using your arms much. Regular exercise routines including weight lifting can typically restart at five to six weeks. If you lift heavy weights or bodybuild, expect to wait as long as three months before returning to your normal training.
Swelling takes several months to fully resolve, and your final chest shape may not be apparent for three to six months. Scars continue to mature and fade for a year or more.
Complications and Risks
The overall complication rate for masculinizing chest surgery is about 12%. Early reoperation is needed in 4 to 9% of patients, most commonly to drain a hematoma (a collection of blood under the skin) or to treat infection. Hematomas occur in 1 to 2% of breast reduction patients generally, but the rate runs higher among transgender patients, reported at 5 to 11% in some groups.
For those who have free nipple grafts, there’s a small risk of partial or complete graft failure, where the transplanted nipple doesn’t survive. Overall nipple loss rates are 1% or less, though some degree of reduced pigmentation and flatter nipple projection is common even when the graft takes well.
Sensation Changes
Some loss of chest sensation is expected with any technique, though the extent varies. Keyhole and periareolar methods preserve more feeling because the nerves stay intact. With double incision and free nipple grafts, nerves are cut and must slowly regrow. That regrowth happens at about a millimeter per day, so meaningful recovery can take up to a year. Some people regain partial sensation, while others experience permanent numbness across parts of the chest. Nerve pain, tingling, or hypersensitivity can also occur during the healing process as nerves reconnect.
