Eighty-four consecutive breast reconstructions using a textured silicone tissue expander

Area of Science:

• Plastic Surgery
• Biomaterials Science

Background:

• Smooth-surface silicone tissue expanders for breast reconstruction present challenges including capsular contracture, displacement, infection, and pain.
• Remote fill valves associated with smooth expanders can also lead to complications.

Purpose of the Study:

• To evaluate the efficacy and safety of a novel textured-surface silicone expander with an integrated fill valve in breast reconstruction.
• To compare the outcomes of textured expanders against known issues with smooth expanders.

Main Methods:

• Eighty-four consecutive breast reconstructions were performed using textured silicone expanders by a single surgeon.
• Intraexpander pressures were measured during the expansion process.
• Patient charts, photographs, and procedural data were collected and notarized.

Main Results:

• Eighty-one reconstructions were completed with minimal complications and no expander losses.
• Average tissue expander volume was 580 cc, with an average expansion duration of 5.6 months.
• 84% of reconstructions were completed in two procedures, with 17 long-term adjustable expander/implants requiring only one operation.

Conclusions:

• Textured-surface silicone expanders with integrated fill valves simplify breast reconstruction and reduce complications associated with smooth expanders.
• These textured expanders facilitate easy expansion with minimal patient discomfort, creating a soft tissue envelope for implants.
• The use of textured expanders leads to aesthetically pleasing breast reconstructions with improved patient outcomes.
