Comprehensive Assessment of Lower-Face Volume Reduction Using Laser-Assisted Liposuction as an Additive Procedure in Asian Rhytidectomy.

Abstract

The most important factor that distinguishes a youthful appearance from an aged one is the shape of the lower face. This study aimed to examine the outcome of volume reduction of the lower face using laser-assisted liposuction (SmartLipo) at the time of rhytidectomy in Asians. There were 20 patients (Group 1) for whom only extended deep-plane rhytidectomy were performed, while extended deep-plane rhytidectomy with laser-assisted liposuction was performed on 42 patients (Group 2). This study was performed retrospectively. The FACE-Q questionnaire was given to evaluate the subjective result of the patient. Efficacy was evaluated by measuring the fat quantity at the midpoint and anterior border of the masseter muscle on each side by using an ultrasound scan in Group 2. Then, the correlation between the change in the quantity of fat and the FACE-Q was investigated. The overall satisfaction, and satisfaction for the lower face, jawline, and the area under the chin were significantly higher for Group 2 for which the procedure was concurrently performed in comparison to Group 1. In Group 2, change in the fat was reduced by 21.2% (Rt.) and 22.5% (Lt.) at the mid-point and 24.5% (Rt.) and 26.4% (Lt.) at the anterior border of the masseter muscle. Changes in the fat quantity and lower face satisfaction displayed a significant correlation. With a greater reduction in fat quantity, the score of lower face satisfaction was higher. In addition, with a higher level of satisfaction for the lower face and jawline, the overall satisfaction score displayed a higher positive correlation. Laser-assisted liposuction was useful for the additive procedure at the time of rhytidectomy and improved patient's satisfaction after surgery.
