BACKGROUND
Fat injection for soft tissue augmentation is a common procedure in plastic surgery. Because the limitation of fat injection is its resorption, understanding how different handling techniques affect adipocyte survival is crucial to optimizing long-term results.
OBJECTIVE
In this study; we sought to determine the effect of aspiration and injection cannula diameters on adipocyte viability.
METHODS
Fat aspiration samples were obtained from 6 female patients undergoing abdominoplasty. Viable adipocytes were counted at fat suspension, which was obtained with 2-, 3-, and 4-mm-diameter aspiration cannulas and injected with 1.6-, 2-, and 2.5-mm-diameter injection cannulas.
RESULTS
A greater number of viable adipocytes were detected using a 4-mm-diameter aspiration cannula (419 x 10(4) cell/1 mL, P < .05) and a 2.5-mm-diameter injection cannula (410 x 10(4) cell/1 mL, P < .05).
CONCLUSIONS
The use of wider-diameter cannulas can potentially improve fat graft survival and reduce fat graft resorption.
背景
脂肪注射用于软组织填充是整形手术中的常见操作。由于脂肪注射的局限性在于其吸收，了解不同的处理技术如何影响脂肪细胞存活对于优化长期效果至关重要。
目的
在本研究中，我们试图确定吸脂和注射套管直径对脂肪细胞活力的影响。
方法
从6名接受腹部整形手术的女性患者身上获取脂肪抽吸样本。在脂肪悬浮液中对活脂肪细胞进行计数，脂肪悬浮液通过直径为2毫米、3毫米和4毫米的吸脂套管获取，并使用直径为1.6毫米、2毫米和2.5毫米的注射套管进行注射。
结果
使用直径4毫米的吸脂套管（419×10⁴细胞/1毫升，P<.05）和直径2.5毫米的注射套管（410×10⁴细胞/1毫升，P<.05）时检测到更多的活脂肪细胞。
结论
使用直径更大的套管可能会提高脂肪移植的存活率并减少脂肪移植的吸收。
