# How to Simulate a Bichectomy

A **bichectomy** (buccal fat removal) is a popular aesthetic procedure that refines facial contours by reducing volume in the cheek area. With [**Arbrea Face**](https://arbrea-labs.com/docs/how-to-use-arbrea-face/), plastic surgeons can create **precise and realistic simulations** to help patients visualize potential outcomes before undergoing surgery.

In this tutorial, we’ll guide you step by step on how to use **the Local Changes tool and the Vector Tool** to **simulate a bichectomy accurately**.

## **Understanding the Tools for a Bichectomy Simulation**

To simulate a bichectomy in **Arbrea Face**, we use two main tools:

### **1. Local Changes Tool**

- Allows you to **add or remove volume** in specific areas of the face.
- Provides precise control over **how much fat is removed**, ensuring a natural and realistic result.

### **2. Vector Tool**

- Highlights the modifications made.
- Helps showcase the **before-and-after difference clearly** to the patient.

## **Using the Cheek Tool to Simulate Buccal Fat Removal**

1. **Open Arbrea Face** and select the patient's image or 3D scan.
2. Click on the **Local Changes Tool**.
3. Adjust the **injection area size**:
   - **Avoid using the maximum setting**—keep it **medium** for better control.
   - You can **increase or decrease the size** based on the precision needed.

## **Removing Volume with Local Changes**

1. **Select the "Remove Volume" option** (instead of adding volume).
2. Adjust the intensity **close to the minimum** for a subtle effect.
3. **Use your finger** to carefully apply the tool **over the cheek area** where fat reduction is desired.
4. **Rotate the model** to ensure even adjustments on both sides.
5. If one side has **too much reduction**, use the undo function to **refine the simulation**.

## **Checking the Modifications with the Vector Tool**

1. Open the **Vector Tool** to highlight the changes.
2. The tool **color-codes the depth of volume removal**, making it easier to evaluate the modifications.
3. If adjustments are needed, go back and fine-tune the volume removal for a **balanced result**.

## **Viewing the Before-and-After Simulation**

Close the tool and **toggle the before-and-after view** to show the transformation.
 Compare the results **side by side** for a clearer patient discussion.
 Highlight the improvements in **facial contouring and definition**.

## **Conclusion**

The **bichectomy simulation tool** in **Arbrea Face** simplifies **facial contouring planning** with **precise fat removal adjustments, real-time modifications, and enhanced visualization options**. By utilizing **the Vector Tool, simulation refinements, and before-and-after comparisons**, surgeons can enhance consultations and achieve accurate **pre-operative planning**.
