Infraorbital Hollow Rejuvenation: Considerations, Complications, and the Contributions of Midface Volumization

Abstract

Abstract   Infraorbital hollows are one of the most common target areas for facial aesthetic treatment; however, they are often perceived to be challenging to treat due to the complex anatomy of the periorbital area, concurrent deformities, and risk of complications. Treatment options include surgical (eg, lower eyelid blepharoplasty with fat transposition or injections) and nonsurgical approaches (eg, fillers). Among these approaches, filler injections have become common practice because they are minimally invasive and provide long-term patient satisfaction. In particular, hyaluronic acid (HA) fillers have been shown to be safe and effective for infraorbital hollow rejuvenation. This review provides an overview of infraorbital hollows, including periorbital anatomy, etiology, clinical assessment, and overlapping deformities, such as malar mounds, festoons, and dark circles under the eyes. Patient and HA filler product selection, injection techniques, as well as potential adverse events, such as bruising/swelling, lower eyelid and malar edema, and vascular occlusions, are discussed. This review also highlights the importance of midfacial volumization to improve outcomes in the infraorbital region and in the overall aesthetic appearance. By selecting appropriate patients and attaining proficiency in periorbital anatomy and infraorbital hollow rejuvenation techniques, clinicians can safely and successfully perform HA filler injections that result in high patient satisfaction.
