Top surgery results vary significantly depending on the technique used, your body type, and whether the goal is a masculine, feminine, or gender-neutral chest. For masculinizing procedures, the most visible feature is typically a pair of horizontal scars across the chest, with nipples repositioned to sit naturally on a flat contour. Feminizing procedures add volume through implants, with scars hidden in less visible locations. Here’s what to expect visually at every stage.
Masculinizing Top Surgery Techniques
The two most common approaches for creating a flat or masculine chest are double incision mastectomy and periareolar mastectomy. Which one you’re a candidate for depends mainly on your chest size and skin elasticity, and they produce very different visual results.
Double incision is the most widely performed technique. The surgeon makes two horizontal incisions, one along the lower border of the pectoral muscle and one in the crease below the chest. All breast tissue and excess skin are removed between these lines, and the nipples are resized and grafted into a new position higher on the chest. The result is a flat chest with two horizontal scars that follow the natural shadow line of the pectoral muscles. When placed well, these scars visually emphasize the pec line rather than looking like surgical marks.
Periareolar (sometimes called keyhole) mastectomy uses a small crescent-shaped incision along the lower half of the areola. Because tissue is removed through this smaller opening and no skin is excised, the only visible scar sits right at the edge of the areola, where it blends with the natural color transition. This technique works best for people with smaller chests and good skin elasticity, since it can’t remove excess skin the way a double incision can.
How Scar Shape Varies
Even within the double incision method, scar shapes differ. People with less excess skin and fatty tissue on the lateral and central chest tend to get straighter scars, placed slightly above the inframammary fold and running more or less horizontally. If you carry more tissue around the sides of your chest or toward the center, the surgeon may need to extend the incision into those creases, producing a contoured or slightly curved scar that tapers upward at the ends.
Some people specifically request curved scars that follow the lower breast fold more closely, which can create a more gender-fluid appearance. Others opt for connected scars that join in the center of the chest. The final shape is a conversation between your anatomy and your aesthetic goals.
What Happens to the Nipples
In a standard double incision, the nipples are completely removed during surgery, trimmed to a smaller diameter, and sewn back onto the chest as free grafts. Because the grafts heal without their original blood supply, they tend to look flatter and lighter in color than before surgery. Some people experience partial or full loss of pigment. The texture can also change, with grafted nipples sometimes appearing smoother or slightly raised compared to their original state.
A newer nipple-sparing technique keeps the nipples attached to the skin throughout the procedure. Instead of grafting, the surgeon makes crescent-shaped incisions on the lateral chest that allow the nipples to shift outward and settle into a natural position. The result is nipples that retain more of their original color, projection, and sensation, though they may sit slightly lower and more lateral than with the graft method.
Chest Contouring for a More Defined Look
Some surgeons go beyond tissue removal to actively sculpt the chest. This can involve ultrasound-assisted liposuction to remove fatty tissue around the areola and in the armpit area, creating sharper definition along the edges of the pectoral muscles. In some cases, fat is strategically injected into and around the pectoral muscle to build out a more angular, pentagonal chest shape with defined borders along the sternum, the lower pec line, and the lateral chest wall. The amount of fat transferred typically ranges from 60 to 350 cc per side.
Feminizing Top Surgery
For transfeminine patients, top surgery means breast augmentation with implants. The visual outcome depends largely on where the implant is placed relative to the chest muscle.
Subpectoral (under the muscle) placement works well for people with thinner frames or less developed breast tissue from hormone therapy. The muscle layer over the implant creates a smoother, more gradual slope and reduces visible rippling. The tradeoff is that strong pectoral muscles can push the implant outward over time, and the recovery tends to be more uncomfortable.
Subglandular (over the muscle) placement is an option for people who’ve developed more breast tissue on hormones, generally reaching later stages of breast development. This placement involves a less painful recovery and can look more natural when there’s enough soft tissue to cushion the implant. However, the wider spacing between nipples on a hormonally developed transfeminine chest means surgeons need to be careful not to create breasts that sit too far apart.
What Recovery Looks Like
Immediately after masculinizing top surgery, your chest will be wrapped in a compression vest. You won’t see much of the actual results for the first week or two. Most surgeons place Jackson-Pratt drains, small bulbs connected to tubes that exit near the incision and collect fluid from the surgical site. The fluid starts out dark red and gradually shifts to light pink, then yellow, then clear as healing progresses. You’ll need to empty these bulbs regularly by squeezing them flat to maintain gentle suction.
Swelling is significant in the first few weeks and can obscure the final shape of your chest. Some people develop seromas, pockets of fluid that collect under the incision and feel like soft, squishy bumps. These aren’t dangerous on their own but can delay the resolution of swelling by weeks or even months. Signs to watch for include increasing pain, warmth, skin discoloration, or wound edges pulling apart, which could indicate infection or the wound reopening under pressure.
How Scars Change Over Time
Fresh scars from top surgery are red, raised, and firm. This is normal. Over the first six months, they gradually soften and begin to flatten. Between six and twelve months, the pigment lightens, the tissue becomes more pliable, and the scars start to blend more with surrounding skin. Full scar maturation can take 12 months or longer. People with darker skin tones may experience more noticeable scarring or hyperpigmentation that takes additional time to settle.
The chest shape itself also continues to change during this period. Initial results can look boxy or uneven due to swelling, but as fluid resolves and tissues settle, the contour becomes more defined. Many people find the results at one year look significantly different from the results at three months.
Sensation After Surgery
Loss of chest and nipple sensation is one of the most common concerns, especially with free nipple grafts. In standard double incision surgery without nerve repair, many patients experience permanent reduction in nipple sensation. A 2024 study in JAMA Network Open found that a targeted nerve reconnection technique performed during surgery significantly improved outcomes: 40% of patients who had the nerve repair could distinguish between two points of contact on the nipple, compared to 0% of those who had standard surgery without it. Improvements extended to temperature detection, pressure sensitivity, and erogenous sensation.
Periareolar and nipple-sparing techniques generally preserve more sensation because the nerve connections to the nipple aren’t fully severed. If sensation matters to you, it’s worth asking your surgeon specifically which nerve-preservation techniques they use.
Who Is Eligible
Under the most recent international standards of care, adults seeking top surgery need to demonstrate sustained gender incongruence, the capacity to consent, and an evaluation of any mental or physical health conditions that could affect surgical outcomes. A single assessment from a qualified health professional is sufficient. For adolescents, the criteria include emotional and cognitive maturity to provide informed consent, and at least 12 months of hormone therapy (unless hormones aren’t desired or are medically contraindicated). Requirements vary by country, insurance provider, and individual surgical practice.
