How to Simulate Asymmetries

Gjiri Arbrea offers an intuitive and comprehensive guide on how to simulate asymmetries, enabling surgeons to accurately analyze, plan, and visualize surgical adjustments using AI-powered simulations. This guide walks you through the step-by-step process of measuring asymmetries, adjusting breast volume, selecting implants, modifying the nipple position, and visualizing surgical scars to enhance pre-operative consultations.

Selecting the Measurements #

1. Open Arbrea Suite and select your patient’s image or 3D scan.
2. Click on the Measurements tool to analyze breast volume differences.

   3. By clicking again, you can switch between measurement mode and volume analysis to assess the asymmetry accurately.

Once measurements are visible, we can move on to adjusting the volume.

Adjusting Breast Volume for Symmetry #

How to Change from Measurements to Volume Mode #

1. Activate Volume Mode by switching from measurements to volume settings.
2. The software will automatically enter Reduction Mode (Step 1), which is used for:
   • Volume reduction
   • Mastopexy (breast lift)
   • Implant replacement planning

How to Reduce the Volume of Each Breast Individually #

By default, both breasts adjust together, but asymmetry correction requires independent adjustments:

1. Deactivate the Lock – This unlocks the ability to modify each breast separately.
2. Reduce the right breast volume significantly.
3. Reduce the left breast volume slightly to maintain symmetry.

At this stage, the initial correction of asymmetry is complete.

Choosing the Right Implant #

Once volume correction is done, we move to Step 2, where we select implants to restore shape and projection.

How to Choose an Implant from the Catalog #

1. Open the Implants Catalog.
2. Select a brand (e.g., Mentor).
3. Filter options based on:
   • Shape (Anatomic, Round)
   • Projection (Moderate, High, Extra High)
4. Choose an appropriate implant and apply it to the patient.

If the implant placement is not perfect, adjustments can be made using the Shape Tool.

Adjusting Implant Position and Lift #

Once the implant is applied, we can refine its position, lift, and overall symmetry.

How to Adjust the Implant and Lift #

1. Open the Shape Tool.
2. Use the sliders to:
   • Lift the breast for a more youthful position.
   • Increase fullness in the upper pole if needed.
   • Move the implant to ensure correct alignment.

After these refinements, the breast shape and symmetry are significantly improved.

Modifying the Nipples for a Natural Look #

To ensure perfect symmetry, it’s essential to reposition the Nipple-Areola Complex (NAC).

How to Adjust the Nipples #

1. Open the NAC Tool (Nipple-Areola Complex Tool).
2. Define the nipple size and exact target position.
3. Adjust the positioning for natural alignment with the new breast shape.

This ensures that both nipples are positioned symmetrically, complementing the surgical plan.

Displaying Surgical Scars #

Arbrea Suite does not show scars directly, as scar healing varies. However, it provides scar indicators to give patients a general idea of where scars will be.

How to Show and Hide Scars #

1. Open the Scars Indicator Tool to place surgical scar markers.
2. Use Bookmark to save the results.
3. Hide the scars if necessary to present a clean simulation to the patient.

This helps set realistic expectations while maintaining a professional and aesthetic visualization.

Presenting the Results to the Patient #

How to Hide the Tools for a Clear Patient View #

Once you’ve finalized the simulation:

Hide unnecessary tools to focus on the results.
Lend the iPad to the patient for an interactive experience.
If needed, return to the implant selection and refine the results further.

This ensures a smooth and engaging consultation where patients can clearly understand the before-and-after transformation.

Conclusion #

Gjiri Arbrea simplifies the way on how to simulate asymmetries with precise measurement analysis, volume adjustments, and implant customization. By utilizing nipple position refinements, scar visualization, and AI-powered simulations, surgeons can enhance consultations and achieve accurate pre-operative planning.
