Background:
Radiofrequency-assisted liposuction (RFAL) is a new choice in energy-assisted body-contouring techniques. The purpose of this study is to observe the clinical effect and safety of RFAL on lower face and neck contouring under local anesthesia, and different outcome compared with traditional liposuction.
Methods:
From November 2016 to November 2020, a total of 72 patients with fat accumulation and skin laxity in lower face and neck, including 42 patients underwent subcutaneous radiofrequency after liposuction (group A) and 30 patients underwent traditional liposuction only (group B). The patient’s parameters recorded involved age, sex, body mass index, the volume of fat aspirated, energy delivered, operative time, and complications. They were photographed for comparison before and after treatment. At 3 and 6 months after the operation, improvement in skin tightening and patient satisfaction was surveyed postoperatively and assessed by third-party surgeons.
Results:
At 6 months after the operation, evaluations scores of the contouring outcome had significant difference between 2 groups (3.0±0.9 versus 2.5±1.0, P=0.045). There was no significant difference at 3 months (2.8±1.0 versus 2.6±1.0, P=0.265). Although the satisfaction rate of group A was higher than that of group B both at 3 months (76.2% versus 66.7%) and 6 months (80.9% versus 60.0%), there were no significant differences in average score (P>0.05). No significant complications or adverse events requiring further medical or surgical intervention after treatment.
Conclusion:
Subcutaneous radiofrequency after Liposuction is a safe and effective treatment that can achieve significant improvement of the fat accumulation and skin laxity of the lower face and neck under local anesthesia.
