Masculinizing Chest Surgery

The goal of transmasculine top surgery, or masculinizing chest surgery, is to remove the breast tissue from both breasts and create a masculine or nonbinary appearance to the chest.

What words should I know about transmasculine top surgery?


Pigmented skin surrounding the nipple.

Double-incision technique

An incision is made in the breast fold, and a second incision is made on the breast skin. After the breast tissue and excess skin is removed, the upper incision is pulled down to the breast fold and the skin is closed. The nipple and areola are removed and then reattached with this technique.

General anesthesia

Drugs and/or gases used during an operation to relieve pain and alter consciousness.


A surgical technique to reattach your nipple and areola.


Blood pooling beneath the skin.

Intravenous sedation

Sedatives administered by injection into a vein to help you relax.

Keyhole technique

A small incision is made along the lower border of the areola, and excess breast tissue is removed through the incision. Skin cannot be removed with this technique.

Local anesthesia

A drug injected directly to the site of an incision during an operation to relieve pain.


The removal of the whole breast.

Periareolar technique

An incision is made circumferentially around the areola, and a larger circular incision is made to remove excess skin. The remaining skin is then drawn in closer to the areola.
