结论分期分段结扎缩窄蒂部法简便易行，安全可靠，可以缩短皮瓣断蒂时间。
Conclusion it is safe and reliable to cut off the pedicle through thinning it by stages and sections, and the pedicle cut-off time can be shortened.
结果：薄皮瓣在外观、手功能恢复、皮瓣长宽比例、皮瓣断蒂时间等方面优于传统皮瓣。
Results: The cosmetic and functional result were all satisfactory, pedicle division time and length_width ratio were advantaged, compared with conventional skin flap.
断蒂后皮瓣与骨皮瓣一期成活，后期复查移植骨成活并且增粗。
After the pedicle, was cut, the flap and bone flap survived in the initial period.
皮瓣中段血管构筑的变化起一个“中介蒂”的作用，是皮瓣能够早期断蒂及超过传统长宽比例可以成活的基础。
We conclude that the middle part of the flap works as an "intermediary pedicle", and is the basis of the early pedicle division and superior survival ratio of the flap.
