DIEP Flap Breast Reconstruction Using 3-dimensional Surface Imaging and a Printed Mold

Area of Science:

• Plastic Surgery
• Biomedical Engineering
• Medical Imaging

Background:

• 3D surface imaging offers advanced digital quantification of breast tissue.
• Deep inferior epigastric artery perforator (DIEP) flap is a common method for breast reconstruction.
• Achieving symmetry and satisfactory cosmetic outcomes remains a key goal in breast reconstruction.

Purpose of the Study:

• To evaluate the utility of 3D surface imaging and 3D-printed molds in DIEP flap breast reconstruction.
• To assess the efficiency and cosmetic results of this novel approach.
• To determine if this method simplifies the process of achieving breast symmetry.

Main Methods:

• 11 unilateral breast reconstructions using DIEP flaps were performed (5 immediate, 6 delayed).
• Preoperative planning involved 3D surface imaging for flap volume estimation.
• Intraoperative shaping utilized 3D-printed molds based on the contralateral breast's inverted shape.

Main Results:

• 3D surface imaging facilitated easier surgical planning.
• 3D-printed molds effectively shaped the breast neoparenchyma.
• Postoperative 3D measurements confirmed satisfactory symmetry and cosmetic outcomes.

Conclusions:

• DIEP flap reconstruction combined with 3D surface imaging and 3D-printed molds is a viable technique.
• This approach offers a simple, quick, and effective method for achieving symmetric breast reconstruction.
• The technology aids in improving cosmetic results and patient satisfaction.
