摘　　要：　目的　探讨翻转双蒂胸舌骨肌皮瓣及去表皮翻转双蒂胸舌骨肌皮瓣修补气管缺损后的转归。方法　以18只兔作为实验对象,在气管前壁造全层圆形缺损,分别用翻转双蒂胸舌骨肌皮瓣(皮瓣组)及去表皮翻转双蒂胸舌骨肌皮瓣(去表皮组)修补,于术后2、4、8个月处死动物,用肉眼及组织学切片观察。结果　8个月时皮瓣组移植物与气管交界处可见假复层纤毛柱状上皮从外周长入,但中央大部分仍为复层鳞状上皮,而去表皮组移植物表面全部被假复层纤毛柱状上皮覆盖。结论　去表皮肌皮瓣修补气管缺损较肌皮瓣容易转变为气管黏膜上皮。Objective To study the long-term changes of sternohyo id myocutaneous rotary door flap and epidermis-removed flap after tracheal reconst ruction with them.Methods Eighteen rabbits were used in t his study.The round defect of tracheal frontal wall was made and both sternohyoi d myocutaneous rotary door flap and epidermis-removed flap were used to repair t he defect.The animals were executed at 2,4,8 month after the operation and obser ved the changes of flap by naked eye and histological section.Results Pseudostratified ciliated columnar epithelium was observed to have grown from around at the mucoctaneous junction eight month after the operation a nd squamous epithelial was still be seen in the center of flaps ,while the graft of epidermis-removed flap completely became ciliated.Coclusion Epidermis-removed flaps are more easily ciliated than flaps in the trache al reconstruction.
