Abstract
|
|
|
|
De-epithelialization is a technique that thins out the epidermis layer of the skin to resurface defects in a cavity or to implant a flap pedicle subcutaneously, preserving the subdermal plexus to support the vascularity of the flap. However, in reduction mammoplasty, de-epithelialization of the pedicle is a time-consuming and tedious step. Although various methods have been proposed to facilitate the completion of this step, a standard has not been established. We used a digital automatic injector that could inject a mixture of lidocaine and epinephrine at a constant, adjustable rate without any special effort. With this method, we could inject local anesthetic into the junction of the epidermis and dermis accurately, which saved time by making dissection easier (hydrodis-section) and decreased bleeding during de-epithelialization. Furthermore, we could use less of the lidocaine and epinephrine mixture, thereby reducing its potential side effects.
