Gland Excision for Gynaecomastia: Subcutaneous Mastectomy and the Periareolar Incision

Gland excision for gynaecomastia, also called subcutaneous mastectomy, is the surgical removal of the firm glandular disc that sits directly behind the nipple, usually through a small periareolar incision hidden at the lower edge of the areola. It is the part of the operation that actually treats true gynaecomastia, because the gland is a fixed structure that liposuction cannot clear and diet or training will not shift¹.

For a long time I assumed liposuction was the whole answer, and the firm fullness I could feel right behind each nipple was just stubborn fat that a cannula would eventually get. It was not. The thing I could pinch and roll under the skin was gland, and it had to be cut out, not sucked away. This is the plain account of that half of the operation: what gland excision is, why it is the bit that matters, and what it costs you in scar and risk. For how it fits the whole picture, start with gynaecomastia surgery.

What is gland excision?

Gland excision is a subcutaneous mastectomy: the surgeon lifts the skin off the glandular disc behind the nipple and cuts the gland out, leaving the skin, the nipple and the underlying muscle in place. It removes the fixed breast tissue that defines true gynaecomastia, as opposed to the soft fat around it².

The word mastectomy sounds bigger than it is here. This is not the removal of a whole breast; it is the excision of a coin-sized to palm-sized pad of firm tissue from under the nipple, working through a short incision. The gland is what you feel as a distinct, sometimes tender disc, and it is what will not move no matter what you do to the rest of your chest, however much fat you lose around it.

Why the gland has to be cut out

Liposuction thins the fatty component but cannot remove the firm glandular disc, so leaving the gland behind is the single commonest reason a chest looks better for a while and then does not. Recurrence is reported at around 35% after liposuction alone, falling to under 10% once the glandular tissue is excised³.

This was the figure I most needed and least often saw written down. A cannula slides past dense, fibrous gland; it clears soft fat. So a liposuction-only quote on a chest that is mostly gland is treating the wrong tissue, and the fullness the man came in about is exactly the part left behind. The fat and the gland are usually taken together, which is why combined liposuction and excision is the standard operation for most true gynaecomastia, with liposuction for gynaecomastia handling the fatty half.

The periareolar incision

The gland is almost always reached through a periareolar incision, a small cut following the lower border of the areola where the darker areolar skin meets the paler chest skin, which hides the scar in that natural colour change. From that opening the surgeon works under the nipple to lift and excise the gland¹.

The reason the scar hides so well is the join it follows: the eye reads the edge of the areola as a line anyway, so a fine scar sitting on it tends to disappear as it fades over months. Grade decides whether this small incision is enough. Larger, skin-stretched chests may need longer incisions and the nipple repositioned, a bigger operation with more visible scars. When I first saw mine healed, the line at the lower edge of the areola was genuinely hard to find unless I knew where to look.

How the excision is done

Gland excision is usually done under a general anaesthetic, though smaller cases can be done under local anaesthetic with sedation, takes roughly 1 to 2 hours when combined with liposuction, and is almost always a day-case, so most men go home the same day. A small drain is sometimes left for a day or two to stop fluid collecting⁴.

In practice the fat is usually addressed first with liposuction, which also helps release and define the tissue planes, and the gland is then excised through the periareolar incision. The chest is closed, and you leave in a compression vest worn day and night, commonly for 4 to 6 weeks to support the tissue and limit swelling.

The crater deformity: the risk specific to excision

The risk that belongs to excision rather than to liposuction is contour: taking too much gland under the nipple leaves a dished or saucer-shaped hollow (a crater deformity), while taking too little leaves residual firmness, and both are leading reasons men come back for more surgery. Judgement about how much to leave matters more than how much comes out³.

This is the honest counterweight to the recurrence figure. The temptation to clear everything under the nipple is exactly what produces a nipple sitting in a dip, and a small button of tissue left deliberately beneath the areola is often what keeps the contour natural. Getting it wrong in either direction is the commonest reason for a gynaecomastia surgery revision, alongside the general surgical risks (haematoma at roughly 5.8% and seroma at around 2.4%) set out in the wider risk account.

Scars and nipple sensation

The periareolar scar is usually well hidden and fades over months, and altered nipple sensation is common early because the excision works directly beneath the nipple, but numbness or hypersensitivity usually recovers over weeks to months, with permanent change uncommon. Hypertrophic or keloid scarring can occur, and partial loss of the nipple from a blood-supply problem is rare but serious⁴.

Mine went strange before it went normal: the nipple felt numb in patches for the first weeks, then oversensitive, then simply settled, over a longer span than I expected. That arc is typical, and the detail is worth reading before you decide, because working right under the nipple is precisely why the feeling changes for a while.

Is gland excision permanent?

Removing the gland is generally permanent, because excised glandular tissue does not grow back, so a properly cleared chest usually stays flat. What brings fullness back is a continuing cause rather than the gland regrowing: ongoing anabolic steroid use, significant weight gain, or an untreated hormonal driver¹.

That is the real payoff of cutting the gland out rather than only thinning the fat. The tissue that defined the problem is gone for good, provided the reason it grew has been dealt with. Excision does not stop the chest ageing or changing with weight, so a stable weight protects the result, and the full long-term picture is in how long do gynaecomastia surgery results last.
