体外超声吸脂500例

目的　探讨体外超声吸脂术的疗效、安全性以及寻求各部位术后体围变化的规律。方法　对 5 0 0例患者的 5 95个部位进行体外超声吸脂术。记录各部位人均注入肿胀麻醉液量及吸出的纯脂肪量 ,并经 1～ 3个月跟踪调查 ,记录各部位术前术后体围的变化 ,对各部位各体围测量点的体围缩小值进行比较和统计学分析。结果　腰腹部、大腿部注入的麻醉液及吸出的脂肪量最高 ,各部位术后均有不同程度的体围缩小 ,随肥胖程度加重 ,腰腹部体围变化越为明显 ,最小腰围、脐围、最大腰围的变化有逐渐减少的趋势 ,但当最小腰围超过 111cm以后 ,术后以脐围的改变最为明显 ,大腿部以及上臂部以中上段改变最为明显。术中术后患者出血量较少 ,痛苦程度轻 ,术后恢复较迅速 ,皮肤平坦 ,无严重并发症发生。患者术后各部位未见反弹迹象 ,结论　体外超声吸脂术安全可靠 ,效果确切 ,受术者易接受。吸脂术后体围的变化可能有规律可循 ,对指导术前咨询以及效果预测有一定的临床意义。

500 cases of external ultrasound-assisted liposuction

Objective To discuss the therapeutic effects and safety of external ultrasound-assisted liposuction and to find out the rules of circumference variation in different body areas after liposuction. Methods External ultrasound liposuction was performed on 500 patients(595 sites).We recorded the volume of anesthetic drugs and the aspirated pure fat as well as the body contour variations of every area at one to three months postoperatively.The decreased dimension at different body sites after liposuction were compared and analyzed. Results The volumes of the anesthetic liquid and the aspirated pure fat were the most in the waist-abdomen and the thigh.After liposuction,the circumstances in different body areas were all decreased to certain degrees.Along with the severity of obesity,changes in the waist-abdomen became more obvious and the decreases of the umbilical circumference,the minimum and the maximum waist circumferences were prone to be less.But when the minimum waist circumference was over 111 cm,obvious changes occurred in the umbilical.Meanwhile,the upper-middle part of the thigh and the upper arm showed larger variations than the lower part.The ultrasound-assisted liposuction had less blood loss and pain.It resulted in smooth skin without severe complications. Conclusions External ultrasound-assisted liposuction is a safe,effective and easily acceptable operation for body contour remodeling.The body circumference variation may have its intrinsic rule,which,to some extent,is meaningful for conducting clinical inquiry and forecasting the operation results.
