Mid-face augmentation via a Le Fort I osteotomy is a commonly performed operation. Advancement of the upper jaw and associated structures (nose, lower cheek areas) can certainly improve function as well as facial aesthetics and harmony. Often, in patients with severe mid-face deficiency, hypoplasia of the maxilla extends all the way up to the infraorbital rims. The receding infraorbital rim contributes to the negative vector of the globes. In patients with this level of mid face hypoplasia, while advancing the maxilla at the Le Fort I level satisfies all of the requirements for orthognathic surgery, the deficient infraorbital rim remains unchanged and. can actually accentuate the negative vector of the globes. This article explains our apprbach in augmentation of the deficient infraorbital rim using alloplastic silicone implants at the time of a Le Fort I osteotomy.
