Horizontal mastectomy is performed under general anaesthesia and involves removing breast tissue through a horizontal incision, allowing the pectoral contour to be defined while simultaneously adjusting the position of the nipple-areola complex.
Recovery usually lasts between 2 and 4 weeks. During this time, it is recommended to wear a compression garment to aid skin adaptation and reduce swelling, and to attend all follow-up appointments for optimal results.
Alignment with Gender Identity
The result is a flat, masculine chest that helps patients feel more comfortable with themselves and regain body confidence.
Reduction of gender dysphoria
Many patients experience discomfort due to breast tissue. After surgery, this discomfort diminishes, improving overall well-being.
Greater freedom of movement
Say goodbye to binders, back pain, and skin irritation caused by prolonged use of compression garments.
Defined masculine chest contour
The horizontal technique is designed to create a flat, defined chest, following safe medical protocols with high precision.
Less visible scars
The placement of the incision makes scars less noticeable, resulting in a more natural and discreet appearance.

Postoperative care is essential for a safe and smooth recovery. Here’s how to take care of yourself after surgery.
Keep dressings and bandages on as directed by your doctor. Clean the scars with saline solution and pat dry gently without rubbing.
Avoid lifting heavy objects and any activities that strain the chest area for at least 2–4 weeks.
Drains and a post-surgical compression vest will be applied after surgery. Your surgeon will advise wearing them for one month to reduce swelling.
Attend all post-operative visits to monitor your recovery and scar healing. You can also raise any questions during these appointments.
Painkillers and anti-inflammatory medication may be prescribed to relieve discomfort and reduce swelling.
Smoking negatively affects healing and increases the risk of infection or complications. It is recommended to avoid smoking during recovery.

FTM top surgery is a gender-affirming surgical procedure designed to create a flatter, more masculine-appearing chest. It is most commonly performed for transgender men and non-binary individuals who wish to reduce or remove breast tissue in order to align their physical appearance with their gender identity.
This procedure, focused on breast tissue removal, is often necessary for serious medical conditions, such as breast cancer or high risk of developing it. It is also a key gender-affirming surgery for transgender individuals, creating a flatter, masculine chest and significantly improving emotional well-being and gender congruence. Choosing a trusted medical team ensures support and confidence throughout the process.
Before FTM top surgery, a comprehensive health assessment is conducted, including imaging – mammograms or MRI-, blood tests, and a detailed medical history review.
