Bulbous-lysing underminers.
The blunt dissection offered by liposuction cannulas has greatly aided surgical undermining such as in face-lift surgery. Herein, we propose a new line of instruments that combines bulbous or blunt dissection with intervening lysing segments. The subgaleal version enables the surgeon to quickly undermine the scalp from ear to ear for scalp reductions in the subgaleal plane. In addition, the subgaleal device aids in the maintenance of the proper dissection plane and is useful in browlifts as well. A closely related "general" undermining device greatly facilitates face-life surgery and has found other uses in the undermining or separation of fibrous tissue planes.
