Nonexcisional Tissue Tightening: Creating Skin Surface Area Reduction During Abdominal Liposuction by Adding Radiofrequency Heating

Abstract
Background: Recent publications show that heat-mediated tissue tightening is a promising treatment for the lax abdomen and may provide better long-term outcomes than traditional suction-assisted liposuction (SAL).

Objectives: The author evaluates the degree and duration of skin surface area contraction, as well as the influence of anatomic location of the treatment region on the degree of tissue tightening, in a study comparing SAL alone vs SAL plus radiofrequency-assisted liposuction (RFAL).

Methods: In this prospective, randomized, split abdominal study, 12 consecutive patients were treated with SAL alone on 1 side and with SAL plus RFAL on the other side. Each patient had 4 (3 × 3-cm) squares—2 per treatment type—tattooed in the lower abdominal region (2 on the right and 2 on the left). The surface area of these squares was measured with the Vectra computerized measurement system (Canfield, Inc, Fairfield, New Jersey) at pretreatment, at 6 weeks posttreatment, and at 1 year posttreatment. All measurements were subjected to statistical analysis using predictive analytic software and were evaluated for statistical significance.

Results: In regions treated with SAL alone, there was a 10.4% mean skin surface area contraction at 6 weeks and 8.3% at 1 year post treatment. The mean skin surface area reduction was 25.8% in regions treated with radiofrequency plus SAL at 6 weeks and 36.4% at 1 year. The anatomic location of each square (medial vs lateral) did not statistically correlate with more or less tissue tightening.

Conclusions: Radiofrequency-assisted tissue tightening, when applied in conjunction with SAL, is effective in achieving greater skin surface area
reduction.

FACIAL SKIN REJUVENATION BY COMBINATION TREATMENT OF IPL FOLLOWED BY CONTINUOUS AND FRACTIONAL RADIOFREQUENCY

Objective
The objective of this study was to evaluate the safety and efficacy of combination facial treatment by 3 technologies. Materials and methods: Eleven patients completed the clinical trial that consisted of alternate treatments of intense pulsed light (IPL) in 3 sessions and continuous fractional bipolar radiofrequency (RF) in 3 alternating sessions, 3 weeks apart. Follow-up visits were made at 6 and 12 weeks following the last treatment. Lesions were evaluated by photographs taken at baseline and at follow-up time points according to predetermined scales.

Results
Results showed statistically significant improvement in wrinkling, pigmentation, vascular lesions, and laxity.

Conclusion
The outcome of the clinical trial performed demonstrates that the combined treatment with IPL, continuous RF, and ablative RF technologies yields a safe and effective combination treatment to address a few clinical indications simultaneously. The results were all statistically significant and no safety issues were recorded.

Peak Power Effect On Skin Rejuvenation Using Ipl: Lumecca Ipl Evaluation

Objective
This article is intended to demonstrate efficiency of the IPL device which is designed to provide the highest peak power and shorter pulse duration for treatment of vascular and pigmented lesions.

Methods and materials
The Lumecca IPL device (InMode Ltd.) was used in a pilot study for treatment of vascular and pigmented lesions. The Lumecca IPL device has a peak power of 3.3 kW/cm² and 3 cm² area. That combination allows for a fluence of 10 J/cm² at a pulse duration of only 3 ms. Such pulse durations correspond to the TRT for vessels with diameters of 70 μm. For comparison, a pulse width of 20 msec corresponds to a TRT of a vessel with diameter of 18 μm. In patients a single treatment with fluence of 8-16 J/cm² and filter of 515nm was performed and followed-up after four weeks.

Conclusion
Single treatment with Lumecca provides significant improvement for majority of patients. Exceptionally short pulses provide improvement even for some patients who had previous treatments with other IPL devices. The high peak power of Lumecca makes its effect on vascular lesions comparable to a pulse dye laser.

Radiofrequency-Assisted Liposuction Compared with Aggressive Superficial, Subdermal Liposuction of the Arms: A Bilateral Quantitative Comparison

Background:
Liposuction of the arms alone may be inadequate for aesthet- ic improvement because of skin laxity. Radiofrequency-assisted liposuction (RFAL) and aggressive super cial liposuction (SupL) have been described to stimulate soft tissue retraction to improve results. We compare the tech- niques and describe a classi cation scheme that factors skin laxity, skin quality, and Fitzpatrick type to provide treatment recommendations.

Methods:
Ten consecutive female patients underwent RFAL of 1 arm and SupL on the contralateral arm. All patients had Fitzpatrick skin types of III, IV, or V with an average body mass index of 26.0. Using uorescent tattooing, key points on the arm skin were measured preoperatively and postoperatively to indicate changes in surface area.

Results:
There were no complications in the group, and all patients re- ported satisfaction with the aesthetic results. All patients showed reduc- tion of measured skin surface areas and skin distances postoperatively. At 1 year, the measured surface area reductions on the anterior arms averaged 15.0% for RFAL and 10.9% for SupL on the anterior arm skin. Posteriorly, RFAL showed 13.1% reduction and SupL 8.1% reduction in the surface areas at 1 year. Linear reduction for RFAL averaged 22.6% and 17.8% for SupL 1 year postoperatively anteriorly.

Conclusion:
Both RFAL and SupL of the arms showed quanti able and sustained reductions in skin surface. Good contour and soft tissue contrac- tion were achieved with both techniques but RFAL with its safety features presents an alternative to SupL, which has a higher complication rate, risk for contour deformities, and steeper learning curve.
