目的 通过组织学观察,探讨颗粒肋软骨游离移植隆鼻术后在体内的转归。方法 对2015年1月至2017年12月在我院行颗粒肋软骨游离移植隆鼻术的患者进行回顾性分析,总结修复手术的原因并将二次修复手术中采集的颗粒肋软骨行组织学检测。结果 颗粒肋软骨游离移植隆鼻术后要求二次修复的原因包括:过矫、移植物显形、移植物移位和鼻背偏斜。修复手术中采集的颗粒软骨呈瓷白色软骨样外观;组织学检测可见典型的软骨陷窝样结构,胞外基质含量丰富。结论 经组织学检测证实,颗粒肋软骨游离移植隆鼻术后在体内能够保持原有的软骨特性。

Objective To explore the in vivo viability of diced cartilage grafts after augmentation rhinoplasty by histological observation.Methods A retrospective analysis was done to the cases of augmentation rhinoplasty with diced cartilage grafts from January 2015 to December 2017.The reason for revision surgery was summarized and the diced cartilage grafts collected in revision surgery were analyzed histologically.Results The reason for revision surgery include overcorrection,visibility,displacement and dorsum deviation.Diced cartilage grafts collected in revision cases exhibited cartilage-like appearance.Histological analysis showed cartilage lacuna structure and abundant extracellular matrix accumulation.Conclusion Diced cartilage grafts exhibit original character in vivo after augmentation rhinoplasty according to histological analysis.
