Vacuum applicators have been effective for cryolipolysis of the abdomen, flanks, inner thighs, back, chest, and arms. However, the lateral thighs have not been easily treated because fat from this area cannot be easily drawn into a vacuum cup.
The authors investigated the safety and efficacy of a prototype applicator for treatment of "nonpinchable" fat in the lateral thighs.
In this prospective, nonrandomized, interventional cohort, multicenter study, a 120-minute unilateral treatment with a prototype conformable-surface applicator was performed on 1 lateral thigh of 40 patients, with the contralateral thigh serving as the control. During follow-up visits at 2 and 4 months, fat reduction was assessed by ultrasound imaging and clinical photography, and patient satisfaction surveys were completed.
Ultrasound data indicated a 2.6-mm mean normalized reduction in fat thickness-a statistically significant reduction vs the untreated control thigh (P = 7.8E-8). According to patient survey responses, 89% of patients would recommend the procedure to a friend; 86% were satisfied with cryolipolysis for the lateral thighs; 86% noticed visible fat reduction; and 97% were likely to undergo a second treatment. A panel of 3 independent blinded physicians correctly identified baseline and posttreatment clinical photographs in 87% of cases. There were no serious adverse events or unanticipated adverse device effects.
The cryolipolysis conformable-surface applicator was safe and efficacious for treatment of lateral thigh fat. Clinical photographs and ultrasound results showed significant reduction in fat thickness, and noticeable reduction in undesirable "saddlebag" bulges. LEVEL OF EVIDENCE 3: Therapeutic.
真空吸脂器已被证明对腹部、侧腰、大腿内侧、背部、胸部和手臂的冷冻溶脂有效。然而，大腿外侧的脂肪不易被吸入真空杯，因此该部位的治疗一直颇具挑战。
作者研究了一种原型吸脂器治疗大腿外侧“捏不起”脂肪的安全性和有效性。
在这项前瞻性、非随机、介入性队列多中心研究中，40名患者的一侧大腿使用原型贴合表面吸脂器进行了120分钟的单侧治疗，对侧大腿作为对照。在2个月和4个月的随访中，通过超声成像和临床摄影评估脂肪减少情况，并完成患者满意度调查。
超声数据显示，脂肪厚度平均标准化减少2.6毫米，与未治疗的对照大腿相比有统计学意义的减少（P = 7.8E-8）。根据患者的调查反馈，89%的患者会向朋友推荐该手术；86%的患者对大腿外侧的冷冻溶脂治疗感到满意；86%的患者注意到脂肪明显减少；97%的患者可能会接受第二次治疗。由3名独立的盲法医生组成的小组在87%的病例中正确识别了基线和治疗后的临床照片。没有严重的不良事件或意外的器械不良影响。
冷冻溶脂贴合表面吸脂器治疗大腿外侧脂肪安全有效。临床照片和超声结果显示脂肪厚度显著减少，不理想的“马鞍袋”凸起明显减少。证据级别3：治疗性。
