Abstract
In prepectoral breast reconstruction, the acellular dermal matrix (ADM) is commonly used to envelop breast implants. Various wrapping methods have been proposed. We present a simple but aesthetic method (ie, the ray method) for wrapping in prepectoral breast reconstruction. Without any complicated design, we folded the four corners of one large ADM and sewed them together to completely envelop the implant. Then, the 6 o'clock corner of the ADM envelope was folded up and sutured to make a pentagonal shape. The other corners of the ADM envelope were quilted to determine the position and movement of the internal implant. Additional sutures were placed on the ADM envelope to separate the implant from the host tissue. The folded 6 o'clock corner was cut to a convex contour and had a diagonal gap to prevent the collection of fluid in the ADM envelope. Finally, the wrapped implant was inserted in the postmastectomy space, and the ADM envelope was spread widely to support soft tissue effectively. This simple design is straightforward for inexperienced surgeons and reduces operation time. The position and movement of the breast implant in the ADM envelope can be easily controlled by using quilted sutures. Subclavian depression and step-off deformities can be minimized by this wide-stretched ADM. By total coverage with a large ADM, the breast implant is separated from the surrounding tissue, and foreign body reactions are reduced. This method is reliable for maximizing the aesthetic advantages of prepectoral direct-to-implant breast reconstruction.
