What Is an Internal Bra? The Metal Bra Technique Explained

An internal bra is a support technique used in breast surgery. This article explains how internal bra surgery works, the materials used, why the term “metal bra” appears online, and the risks to understand. For procedure details and an individual evaluation, see AMG Plastic Surgery’s service page.

What is an Internal Bra for Breast Surgery?

The internal bra technique uses a supportive material within the breast to reinforce the natural tissue. The material acts as an internal support structure. The term describes a surgical technique rather than a separate garment or a single type of implant.

Why is it called a Metal Bra?

“Metal bra” is an informal name sometimes used online for the internal bra technique. It does not mean that the mesh is made of metal. The technique uses surgical support material within the breast. Materials differ, and some meshes are designed to be absorbed by the body over time.

How Does the Internal Bra Technique Work?

In this procedure, I meticulously place a supportive mesh or scaffold beneath the skin and within the breast tissue. This mesh acts like an internal push-up bra, stabilizing the breast tissue and reinforcing the lower pole (the area beneath the nipple). The internal bra technique is especially useful for addressing sagging breasts with loose skin and provides long-term structural support.

The mesh material used is typically biocompatible, allowing for seamless integration with the body’s natural tissue. Over time, tissue growth occurs around the mesh, enhancing durability and creating a natural breast lift effect. I often explain to my patients that the mesh acts like “rebar” to reinforce the natural scar tissue, ensuring a stable, long-lasting result.

Types of Internal Bra Materials

There are several materials used in the internal bra technique, each with its unique benefits:

1. Acellular Dermal Matrix (ADM): This biologic mesh is derived from processed human, porcine (pig), or bovine (cow) tissue, which has been treated to remove cells while preserving the extracellular matrix. Examples include Alloderm, Strattice, and Surgimend.
2. Synthetic Mesh: GalaFLEX is made from poly-4-hydroxybutyrate (P4HB), a resorbable polymer used to create a supportive scaffold.
3. Autologous Tissue: In some cases, a patient’s tissue, such as fascia strips, can be used to create internal support.

While these materials are often used “off-label” for cosmetic breast surgery, they have been extensively tested for other medical applications and have shown successful outcomes in breast procedures. Many surgeons, including myself, have significant experience with these materials and employ them to provide excellent, long-term results for our patients.

Risks of an Internal Bra Breast Lift

While the internal bra technique offers significant benefits, it’s essential to understand the potential risks, which are similar to those associated with traditional breast surgery:

• Infection
• Seroma (fluid accumulation)
• Hematoma (blood collection)
• Implant displacement or malposition
• Mesh visibility or palpability

Discussing these risks with your surgeon is crucial to making an informed decision. With a deep commitment to patient safety and care, I thoroughly explain these considerations during the consultation process.

The Final Word

An internal bra uses supportive material to reinforce breast tissue. Understanding the technique, the materials, and the risks helps explain how it differs from a traditional breast lift. If you are considering internal bra surgery, Dr. Ghaznavi evaluates candidacy in person at the Herndon office.
