Project Name: Personalized Facelift: Eye Tracking Technology in Aesthetic Surgery

Project Summary:  Eye tracking technology has been utilized extensively in marketing and consumer research, and is now being used clinically. For example, autism severity is being evaluated by measuring eye gaze and fixation times in order to create an objective risk assessment algorithm. We use this same technology to analyze the eye gaze patterns and fixation times on the face of patients that have undergone facial aesthetic surgery. Therefore, the purpose of this study is to investigate eye-tracking technology as a novel outcome assessment tool, enhancing our understanding of the ability of facial rejuvenation procedures to shift visual attention away from the prominent signs of facial aging. We hypothesize that an observer's eye fixation and dwell times (visual attention) on the prominent signs of facial aging will decrease following facial rejuvenation procedures. In addition, we predict that the normal facial scan path, consisting of a central triangle of eyes, nose, and mouth, will differ preoperatively due to the distracting facial features in an aging face. Likewise, we also predict postoperative photos will align to the central triangle earlier in the visual scan path sequence. Moreover, we believe that eye tracking technology can provide a powerful link between objective gaze and subjective aesthetic preferences, adding further objective evidence to the strongly visually based field of aesthetic surgery. Furthermore, this technology has immense potential for many applications throughout Plastic and Reconstructive Surgery.

 
Personalized Facelift: Does Skin Composition Influence Outcome? Print

The ASERF Scientific Research Committee and Board of Directors are pleased to announce the following grant award:

Researcher: Lorne Rosenfield, MD

Grant Award: ASERF Interim Grant

Amount Awarded: $70,000

Project Name: Personalized Facelift: Does Skin Composition Influence Outcome?

Project Summary:  Determining if intrinsic differences in skin collagen and elastin influence aesthetic outcomes and tissue relaxation post facelift (rhytidectomy). This is relevant since facelift surgery has reliable and predictable long-term clinical and patient-reported outcomes. However, a proportion of patients exhibit early post-operative recurrence of facial rhytids, despite undergoing a technically comparable procedure to those with successful long-term outcomes. We hypothesize an ‘early recurrence’ cohort of patients exist who are predisposed to a sub-optimal surgical outcome due to inherent structural differences in the collagen and elastin of the facial skin. These patients are intrinsically predisposed to a poor aesthetic outcome, possibly due to the undiagnosed presence of a lower-spectrum (“microform”) of cutis laxa. This study aims to quantify collagen and elastin structure at a histological, immunological and cellular level in skin excised during facelift. Patients will be prospectively followed-up, with post-operative aesthetic outcome compared with pre-operative collagen/elastin data.
