RESUMO
BACKGROUND: A new technique in plastic surgery termed percutaneous radiofrequency dermaplasty (PRD) is described. Customized radiofrequency energy is applied via the percutaneous route to produce skin tightening and fascia contraction at body temperature, avoiding thermal injury. We combine PRD with lipoplasty and call this combined procedure dermaplasty-assisted lipoplasty (DAL). The purpose of this study was to review both the safety and efficacy of DAL. METHODS: We developed the required novel device and technique to perform DAL and then performed a clinical trial including Type I and Type II lipodystrophy female patients undergoing a primary liposuction of the circumferential trunk. The trial comprised two phases. In Phase I, 51 patients were included in a prospective, comparative, controlled trial and divided into two groups. In Group 1, 29 patients underwent DAL, and in Group 2, 22 patients underwent a standard suction-assisted lipectomy (SAL) alone. In Phase II, 84 patients underwent DAL, including 9 cases initially scheduled for a mini-abdominoplasty. RESULTS: Phase I: We found better aesthetic results with DAL (93.1%) than with SAL alone (72.7%) [p < .05]. Postoperative correction of flaccid skin was superior with DAL (93.1%) than with SAL alone (36.4%) [p < .01]. Phase II: DAL achieved good-to-excellent aesthetic results in 94% of the cases. CONCLUSIONS: DAL was found to be a reliable and safe treatment for fat removal with concomitant skin and fascia tightening but without compromising the viability of the overlying skin.

BACKGROUND AND OBJECTIVES: Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. SUBJECTS AND METHODS: Twenty healthy women aged 20-40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. RESULTS: Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group (P<0.05) and in the buttocks (P<0.05) and the posterior thigh areas (P<0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 (P<0.05) and G2 (P<0.05), and in posterior thigh areas, G1 (P<0.05) and G2 (P<0.05). Optimal improvement of skin firmness (G1, P<0.0001; G2, P=0.0034) in the treated areas was observed in both groups. CONCLUSION: We conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results.
RESUMO
BACKGROUND: Skin tightening is a desirable outcome for skin flaccidity. OBJECTIVE: We evaluated the applicability, safety, capacity and intensity of skin tightening with the subdermal 1,064 nm Nd: YAG laser application to the upper arms, and compared the results with liposuction. MATERIALS AND METHODS: Patients with lipodystrophy and mild-to-severe skin laxity of the arms were included (n=28). In half of patients, a single treatment with a subcutaneous laser and liposuction was performed, while the other 14 had a regular liposuction. Treatment parameters, adverse effects and photographic documentation were recorded. RESULTS: Aesthetic improvement and skin retraction was superior by laser lipolysis. The procedure was well tolerated without significant complications. CONCLUSIONS: The subdermal laser-assisted liposuction using a 1,064 nm Nd: YAG laser achieves improved skin tightening.
RESUMO
Com o avanço da tecnologia há demanda cada vez maior por procedimentos minimamente invasivos de rejuvenescimento, como a radiofreqüência (RF) e a luz infravermelha (IR), que oferecem uma opção não cirúrgica para o tratamento da flacidez cutânea. A RF se baseia no aquecimento volumétrico controlado da derme profunda, enquanto a epiderme é preservada através de sistemas de resfriamento, levando a contração imediata do colágeno e neocolagênese tardia. A luz infravermelha é uma fonte de energia alternativa utilizada para promover a retração da pele. A água atua como cromóforo-alvo, permitindo um aquecimento uniforme da derme. A seleção adequada do paciente e o manejo cuidadoso da sua expectativa são fundamentais, uma vez que os resultados clínicos obtidos com RF e IR ainda apresentam baixa previsibilidade e reprodutibilidade e não são equivalentes aos de uma cirurgia plástica. Porém, são técnicas não invasivas e podem oferecer alternativas para o tratamento não cirúrgico da flacidez cutânea.
