# How to Simulate a Gynecomastia

[**Arbrea Breast**](https://arbrea-labs.com/docs/how-to-use-arbrea-breast-an-overview/) provides a precise and intuitive way to simulate **gynecomastia procedures**, allowing plastic surgeons to visualize **male breast reduction results** in real time. With tools like **volume removal, freehand sculpting, and before-and-after comparison**, surgeons can enhance patient communication and streamline treatment planning.

## **Checking the Breast Measurements**

1. Start by loading the patient's scan or photo into **Arbrea Breast**.
2. Click on the [**Measurement Tool**](https://arbrea-labs.com/docs/how-to-take-the-patients-breast-measurements/) to display key metrics such as **chest width, projection, and volume**.

   Check the video below!

**Why It’s Important:**
Provides a **baseline to assess the severity of gynecomastia** and track surgical goals.

## **Removing the Breast Volume**

1. Navigate to the **Reduction Mode**.
2. Use the volume sliders to **decrease excess breast tissue** on one or both sides.
3. Unlock the symmetry if you need to **reduce unevenly**.

 

Helps simulate the **initial phase of male breast reduction surgery**.

## **Refining the Result with the Freehand Tool**

1. Open the **Freehand Tool** to manually sculpt and refine specific areas.
2. This tool provides greater control for adjusting **shape, contour, and fine details**.

 

Useful for simulating **customized surgical outcomes**.

## **Changing the Brush Size**

1. Within the Freehand Tool, adjust the **brush size** based on the area you’re working on.
2. Use a **smaller brush for precise corrections**, or a **larger brush for general contouring**.

 

Gives flexibility for **accurate shaping of the chest area**.

## **Removing Side Volume**

1. Continue sculpting using the **Freehand Tool** to reduce **lateral chest fullness**.
2. This step ensures a **natural, masculine contour** by addressing the outer breast tissue.

Essential for simulating a **balanced and aesthetic chest appearance**.

## **Comparing Before and After**

1. Use the **Before/After toggle** or **side-by-side view** to display the transformation.
2. This comparison allows the patient to **visually understand the procedure’s impact**.

 

Boosts **patient confidence and engagement** during consultations.

## **Conclusion**

Simulating a **gynecomastia procedure** with **Arbrea Breast** is fast, accurate, and interactive. By combining **automatic volume reduction**, **manual sculpting**, and **measurement tools**, plastic surgeons can deliver realistic, patient-specific simulations that support **pre-operative planning and patient education**.
