自体脂肪颗粒隆乳术的适应证及临床分析

Indication and clinical analysis of autogenous fat granule replant mammaplasty

目的探索减少自体脂肪颗粒隆乳术后移植脂肪吸收及提高隆乳效果的方法；总结30例施行脂肪抽吸减肥术联合脂肪颗粒注射隆乳术的手术方法及要点。方法脂肪抽吸采用国内已普遍推行的肿胀法，抽出脂肪500～3250ml。将经过处理后的脂肪颗粒，注射于乳腺后间隙隆乳。其方法为以乳房下皱襞正中部或腋前线为注射进针点，行局部浸润麻醉，左手捏起乳房，将针头穿入乳腺后与胸大肌表面之间的间隙，右手用力将吸入注射器内的脂肪颗粒缓缓推入间隙内，在注射过程中不断变换方向，以利于乳房塑形。结果脂肪抽吸部位减肥明显，效果满意；隆乳30例，随访6～10个月，乳房外形好，吸收少。结论自体脂肪颗粒注射隆乳是一种切实可行的方法，值得临床推广使用。

Objective To explore the methodology of the preventing the absorption after autogenous fat granule mammaplasty, and the main point of the operative methods.. Methods The clinical data were reviewed in 30 cases of patients with liposuction combined with fat-grafting injection for breast mammaplasty in the past four years. The tumescent technique was used in liposuction and the volume of fat tissue aspirated was between 500 ml and 3250 ml. Using appropriate way we prepared pure fat granules and then evenly injected into the layer beneath the pectoralis major muscle, submam- mary layer and subcutaneous layer of the breast, respectively. Results The effect of the method was satisfying because sucking area was significantly decreased. From six months to 10 months follow-up, grafts showed no obvious absorption. The breast looked symmetry. Conclusion Fat grafting injection is a practicable method for breast mammaplasty. The key point is to use appropriate way to get pure fat granule and to prevent infection. It deserves to be recommended.
