目的通过超声技术评估自体脂肪颗粒注射移植隆乳术后脂肪的吸收率.方法超声测量自体脂肪颗粒少量多次注射移植隆乳术者33例,每例接受1～5次注射,每侧每次注入脂肪颗粒50～60 mI,通过超声测量乳房不同位点的腺体后移植脂肪各时期厚度的变化,评价脂肪的吸收率.结果共测量乳房264个位点,其中224个位点脂肪颗粒位于腺体后层;32个位点脂肪颗粒位于胸大肌层;8个位点脂肪颗粒位于腺体层内.腺体后脂肪平均厚度由术前0.2 cm增加到第5次注射后的1.0 cm,隆乳术1个月后腺体后脂肪厚度的平均吸收率为34%～66%.结论自体脂肪颗粒少量多次注射移植隆乳术是一种有效的方式,超声技术是一种有效的诊断监测方法.

Objective To assess the absorbance rate of the fat after the operation of breast augmentation of the repeated injection of low volume, using ultrasonic imaging method. Methods Thirty three patients were injected with low volume of autologous fat (50-60 ml per time) to bilateral breasts for 1-5 times and breast sonographic examination was performed to evaluate the grafted fat tissues. The thickness of the retromammary fat layer before and after each injection was measured to calculate the absorbance index. Results The 264 points of breast were measured in this study. The fat was distributed in the retro-mammary fat layers at 224 points of the breast and in the pectoralis major muscle layer at 32 points of the breast, and the others distributed in the mammary gland layer.The average thickness of the retromammary fat layer increased gradually from 0.2 cm before the first operation to 1. 0 cm after the fifth operation. The average absorbance index one month after each operation was 34 %-66 %. Conclusion The present study demonstrates that breast augmentation by repeated autologous fat graft with low volume injection at each time is applicable and satisfactory and that breast ultrasound is an accurate and simple method to e-valuate the absorbance index.
