The “Boomerang Lift”: A 3-Step Compartment Based Approach to the Youthful Cheek

Background: Autologous fat grafting (AFG) is an important tool for plastic surgeons treating the aging face. Malar augmentation with fat is often targeted to restore the youthful facial contour and provides support to the lower eyelid. The existence of distinct facial fat compartments suggests a step-wise approach may be appropriate in this regard [1]. Here we describe a three-step approach to malar augmentation using targeted deep malar fat compartmental augmentation, termed the "Boomerang Lift". Methods: Clinical patients undergoing AFG for malar augmentation were injected in three distinct deep malar fat compartments: 1. the lateral sub-orbicularis oculi fat (LSOOF), medial sub-orbicularis oculi fat (MSOOF), and lastly to the deep medial cheek (DMC) (n=9). Intra-operative 3D images were taken at baseline and following compartmental injections(Canfield® VECTRA H1). Images were overlaid between the augmented and baseline captures, and the 3D surface changes were analyzed, which represented the resulting "augmentation zone" (AZ). Results: 3D analysis of patients (n=9) demonstrated a unique pattern for AZ consistent across patients. The AZ resembled a boomerang, with the short tail supporting the medial lower lid, and the long tail extending laterally along the zygomatic arch. The upper border was restricted by the level of the naso-jugal interface, and the lower border was defined medially by the nasolabial fold and laterally by the level of the zygomatico-cutaneous ligament. Injections to the lateral and medial SOOF defined the boundaries of the boomerang shape, while the injection to the deep medial cheek provided maximum projection. Conclusions: This is the first description of deep malar augmentation zones described in clinical patients. 3D surface imaging was an ideal method for analyzing the surface change in response to targeted facial fat grafting. Our technique resulted in a reproducible surface shape, which we term the "Boomerang Lift". The authors of this study have no financial disclosures. Corresponding Author: Oren M.
