背阔肌节段肌瓣移植修复面瘫的应用解剖

Applied anatomy of reconstruction of facial paralysis using segmental latissimus dorsi flap

对86侧背闼肌及其内部血管进行了分段观测。1.背阔肌的节段动脉在肌肉的分布具有一定的规律性。2.根据节段动脉的支数可将背阔肌分为4～6个节段肌瓣,其中以外3、4段最薄,血管蒂最长。3.胸背动脉分出内、外侧支的位置在肩胛骨下角平面上方18.5mm、背阔肌外侧缘内侧21.5mm.文中设计了四种形态的节段肌瓣供临床选用参考,并讨论了截取肌瓣的手术入路。

The latissimus dorsi and its segmental vaseularity were observed in 66 specimens. The segmental arteries were found to be regularly distributed within the muscle, on which 4-6 segmental muscular flaps may be based. Among the segmental flaps, the lateral 3rd or 4th one is the thinnest and has the longest vascular pedicle. The segmental blood supply of the muscle makes it possible to design various kinds of segmental flaps.
