Tissue expansion with endoscopy.

Tissue expansion is a time-honored technique in plastic surgery. However, while it is possible to rectify quite severe problems, the technique is not free of complications (e.g., extrusion) and, moreover, it can be a lengthy procedure, often taking months. Endoscopy is increasingly being used in plastic surgery and has the advantage that large areas can be dissected using only small incisions. However, in endoscopic plastic surgery the main problem is the lack of an optical cavity. This means that special retractors are needed to keep skin and fat tissue lifted. This paper describes a technique for the placement of tissue expanders during endoscopy. Incisions are not made in the area that is to be expanded and, thus, there is no risk of extrusion and tissue expanders can be fully inflated intraoperatively. A further advantage is that the procedure reduces patient discomfort to a minimum.
