Potential benefits of laser-assisted liposuction include enhanced body shaping and skin tightening with reduced patient downtime. In this clinical study, we investigate whether additional safety and efficacy are achieved with a diode laser system that includes a novel 924 nm lipid-selective wavelength.
STUDY DESIGN/MATERIALS AND METHODS: Clinical subjects were treated with a continuous-wave (CW) power 924/975 nm diode laser system in the submental area, abdomen, thighs and flanks. Side effects were documented. Efficacy evaluation included investigator-assessed improvements and subject self-assessments.
Study investigators observed good to excellent improvement across all subjects (n = 19) by 3 months post-treatment in all four categories evaluated. Facility of tip advancement was rated as "extremely easy" or "easy" in 83% of rated treatments. "Good" to "excellent" skin textural improvement was observed in 83% of rated subjects. Additional benefits included reduced operator fatigue and uniformity of treatment. Patients tolerated the procedure well with minimal and transient side effects. Immediate side effects of erythema, bruising and edema were graded as mild or trace. No long-term side effects were observed. Seventy-eight percent of all subjects were extremely satisfied with the procedure and 89% would do the procedure again. Eighty-nine percent of subjects felt their appearance of unwanted fat was significantly improved with smoother and tighter skin (72%), and 94% would recommend the treatment to family and friends.
These clinical findings demonstrate that the 924/975 nm diode laser system provides safe and efficacious body shaping, fat reduction and enhanced skin tightening. Ease of movement through the tissue of both the laser system treatment tip and the aspiration cannula resulted in reduced fatigue for the treating physician. Patient benefits included high patient satisfaction, significant reductions in fat, and smoother and tighter skin with minimal downtime.
激光辅助吸脂术的潜在益处包括改善身体塑形效果、紧致皮肤,同时减少患者的恢复时间。在本临床研究中,我们探究一种包含新型924纳米脂质选择性波长的二极管激光系统是否能带来额外的安全性和有效性。
研究设计/材料与方法:临床受试者在颏下区域、腹部、大腿和侧腹接受连续波(CW)功率924/975纳米二极管激光系统治疗。记录副作用情况。疗效评估包括研究者评估的改善情况和受试者自我评估。
研究人员观察到,在所有评估的四个类别中,所有受试者(n = 19)在治疗后3个月均有良好至极佳的改善。在83%的评估治疗中,激光头推进的便利性被评为“极其容易”或“容易”。83%的评估受试者观察到皮肤质地有“良好”至“极佳”的改善。其他益处包括减轻术者疲劳和治疗的均匀性。患者对该手术耐受性良好,副作用轻微且短暂。红斑、瘀伤和水肿等即时副作用被评为轻度或轻微。未观察到长期副作用。所有受试者中有78%对该手术极其满意,89%愿意再次接受该手术。89%的受试者认为多余脂肪外观有显著改善,皮肤更光滑紧致(72%),94%会向家人和朋友推荐该治疗。
这些临床研究结果表明,924/975纳米二极管激光系统可提供安全有效的身体塑形、脂肪减少和增强的皮肤紧致效果。激光系统治疗头和吸脂套管在组织中移动方便,减轻了治疗医生的疲劳。患者受益包括高患者满意度、显著减少脂肪、皮肤更光滑紧致以及恢复时间最短。
