(A) Deep midfacial fat compartments. The deep medial cheek fat is composed of a medial part and a lateral part (not shown). The medial part extends medially almost to the lateral incisor tooth. Augmentation of the deep medial cheek fat will consequently elevate and efface the nasolabial fold. The suborbicularis oculi fat is composed of a medial part and lateral part. With aging, inferior migration of these compartments occurs, as well as an inferior volume shift within the compartments, as seen on this computed tomography (CT) image. Reproduced from Gierloff et al., 2012a, Gierloff et al., 2012b. (B) Before and after hyaluronic acid filler was placed in the fat compartments shown in the CT image using a 25 gauge cannula. Improvement can be seen on the right side of the face in the three-quarter view. The patient was also treated along the lateral upper lid and brow as well as the temples, similar to the patient in Figure 10; however, neuromodulater was also used in the glabella and crow’s feet. Note the increased improvement when both filler and neuromodulater are used together. Reproduced with permission from Fitzgerald and Rubin (2014).
