目的 探讨体外超声吸脂术治疗下肢大小腿脂肪堆积的疗效、安全性 ,以及对操作技巧进行总结。方法 接受吸脂者共 81例 ,根据其要求 ,分别对大腿部 (6 0例 )以及小腿部 (2 1例 )进行体外超声吸脂术 ,记录所注入的麻醉药量和吸出的纯脂肪量 ,以及吸前和吸后 1～ 3个月的腿围变化。结果 大腿部人均吸出脂肪量 36 73ml,最高吸出量 6 10 0ml;大腿正中围缩小 (4.6 5± 1.10 )cm ,最大缩小 12 .5cm。小腿人均吸出脂肪量 6 5 0ml,最高吸出量 12 0 0ml;小腿正中围缩小 (3± 1.0 2 )cm ,最大缩小 9cm。吸脂疼痛程度较轻、出血量少、吸后皮肤平坦、无严重并发症发生、无反弹迹象。在操作过程中 ,熟知腿部脂肪分布特点 ,注射麻醉药量充分、均匀 ,超声时间适度 ,吸刮层次准确是手术成功的根本保障。结论 体外超声吸脂用于腿部脂肪堆积的治疗 ,是一种安全、可靠、有效的方法 ,医师的熟练操作技巧是手术成功至关重要的因素。

Objective To discuss the therapeutic effects and safety of external ultrasound liposuction to adipose tissue of lower extremities and to summarize the operative techniques. Methods According to the requests of 81 patients, external ultrasound liposuction were performed for them on thighs (n=60), and legs (n=21). It was that the volumes of anesthetic drugs and pure fat as well as the variations of body contour between preoperation and one to three months after operation in every area were recorded. Results Fat aspiration volume in thighs was 3673ml per person with the highest 6100ml. The scale of the circumference of thighs decrease (4.65±1.10)cm with the highest 12.5 cm. In legs, fat volume was 650ml per person with the highest 1200ml, scale decrease (3±1.02) cm with the highest 9cm. Patients had less blood loss, less pain and discomfort with even skin appearance and without severe complications. In the course of operation, knowing well the anatomical character of lower extremities, injecting the anesthetic drugs completely, using appropriate ultrasound time, and sucking in uniform layer were all crucial factors to guarantee the success of the operation. Conclusion External ultrasound liposuction is a safe, effective body contour remodeling operation in lower extremities. Skillful operator is a very important element to successful operation.
