Mentoplasty or genioplasty is a simple procedure to enhance facial aesthetics. While usually considered simple, it might present certain di culties during execution, especially when a minimally invasive approach is preferred. Drilling and cutting guides are a valuable tool to overcome such challenges but usually require larger incision and dissection to allow adequate positioning and bone rigid xation. In this article, we describe a novel guide design that permits adequate bone repositioning while preserving minimally invasive protocols.
