本研究的目的是确定游离皮瓣体积在术后长期内是减少还是增加。方法回顾性分析17例患者使用AZE Virtual Place Lexus64三维图像测量游离皮瓣的肌肉和脂肪体积。结果17例患者行腹直肌皮瓣（11例）或股前外侧皮瓣（6例）重建。中位随访时间28.9个月（范围2.148.4个月）。包括40%肌肉在内的皮瓣的总皮瓣体积显著减少（p = 0.011）。平均12个月的最终肌肉体积为50%。无疾病证据患者的最终脂肪体积（平均116.7%）显著高于疾病死亡患者（平均70.3%,p = .007）。结论使用高脂肌比的游离皮瓣是可持续的，并且随着时间的推移可以增加体积，因为移植的脂肪会根据宿主的情况而增加。(c) 2011 Wiley期刊公司头颈，2011年
Background The purpose of this study was to determine whether free flap volume decreases or increases in the long-term postoperative period. Methods We used a retrospective analysis of 17 patients to measure muscle and fat volume in free flap with 3-dimensional (3D) images using the AZE Virtual Place Lexus64. Results Seventeen patients underwent free flap reconstruction with rectus abdominis musculocutaneous flaps (n = 11) or anterolateral thigh flaps (n = 6). Median follow-up was 28.9 months (range, 2.148.4 months). Total flap volume was significantly decreased in flaps including =40% muscle (p = .011). Mean final muscle volume was 50% at an average of 12 months. Final fat volume was significantly higher for cases with no evidence of disease (mean, 116.7%) than for died-of-the-disease cases (mean, 70.3%; p = .007). Conclusion Use of free flaps with a high ratio of fat to muscle is sustainable and can gain volume over time, as transplanted fat can increase depending on host condition.
