The Gynaecomastia Surgery Procedure: Incisions, Anaesthetic, Duration and Drains

Gynaecomastia surgery is usually done under a general anaesthetic as a day-case, taking roughly 1 to 2 hours: the surgeon marks your chest while you stand, then, with you lying flat and asleep, takes the fat with liposuction through one or two tiny stab incisions and cuts the firm gland out through a small periareolar incision hidden at the edge of the areola. Most men go home the same day in a compression vest¹.

The day itself was the part I had built up most in my head and the part that mattered least in the end. I arrived nervous, was marked up standing in front of a mirror, and the next thing I knew I was awake in a vest with a flatter chest under it. This is the plain account of what actually happens between those two points. For how the operation fits the whole decision, start with gynaecomastia surgery.

What happens on the day?

You arrive fasted, the surgeon draws the plan on your chest while you are standing so the tissue hangs in its natural position, you are taken to theatre and put under, and you wake in recovery in a compression vest a couple of hours later. For a standard combined operation the whole hospital visit is a matter of hours, not days, because it is almost always a day-case¹.

The standing mark-up surprised me more than anything else on the day. It is done upright and awake, often in front of a mirror, because a chest looks completely different lying down, and the surgeon needs to see where the fullness actually sits and where the gland is before you are flat and asleep. Those pen lines are the map for the whole operation.

The anaesthetic

Gynaecomastia surgery is usually done under a general anaesthetic, so you are fully asleep, though smaller and mostly fatty cases can be done under local anaesthetic with sedation, where the chest is numbed and you are relaxed but conscious. Which suits you depends on the size of the operation and your surgeon and anaesthetist’s judgement².

The choice is not just about comfort. A general anaesthetic is common where a firm gland is being cut out and both sides are being worked on properly, while a small, purely fatty correction can sometimes be handled awake. The fuller comparison, and what each one feels like going under and coming round, is set out in gynaecomastia surgery anaesthesia.

Where the incisions go

There are two kinds of incision: liposuction goes through one or two tiny stab incisions of a few millimetres, placed low on the chest or in the fold, and the gland is removed through a periareolar incision that follows the lower border of the areola where the darker skin meets the paler chest skin. That colour change hides the scar as it fades².

This was the detail that reassured me most before the day. The scars from a standard combined operation are genuinely small: a couple of dots from the liposuction and a fine line at the edge of the areola that is hard to find once healed. Larger, skin-stretched chests are different and need longer incisions with the nipple repositioned, which is a bigger operation with more visible scarring.

What the surgeon does, in order

The fat is usually taken first with liposuction, which also helps release and define the tissue so the gland is easier to reach, and then the firm glandular disc behind the nipple is cut out through the periareolar incision. Liposuction alone cannot clear the gland, which is why the two are combined for most true gynaecomastia³.

Getting the order right is the whole logic of the operation. The liposuction debulks the fatty part and opens up the plane; the gland excision then removes the fixed disc that no amount of suction or training would shift. Doing both in one sitting is the standard for most true gynaecomastia, and the reason recurrence falls from around 35% after liposuction alone to under 10% once the gland is out⁴.

How long it takes, and getting home

A standard combined operation takes roughly 1 to 2 hours in theatre, longer where surplus skin is removed, and is nearly always a day-case, so most men go home the same day once they have woken fully, eaten, and been checked as steady. Occasionally a man stays one night, more often after a larger skin-removal case¹.

The time in theatre is only a slice of the day. There is anaesthetic preparation beforehand and a few hours in recovery afterwards, so I was in the building far longer than the operation itself took, and I needed someone to drive me home and stay the first night. The chest under the vest looked alarmingly swollen at that point, which is normal and covered in gynaecomastia surgery recovery week by week.

Drains and the compression vest

A small drain, a thin tube leading to a collection bottle, is sometimes left in for a day or two to stop blood or fluid gathering under the chest, and you leave theatre in an elasticated compression vest that is worn day and night, commonly for 4 to 6 weeks. Not every surgeon uses drains and not every case needs one⁵.

If you do wake with a drain, it is usually removed at your first follow-up a day or two later, which is quick if slightly odd-feeling. The vest matters more and for far longer: it supports the tissue, limits the swelling, and helps the skin settle onto the new, flatter contour, which is why it earns its weeks. What it is like to actually live in one is set out in the compression garment after gynaecomastia surgery.
