面动脉肌皮瓣修复口底缺损

RECONSTRVCTION OF THE FLOOR OF MOUTH WITH FACIAL ARTERY MUSCULOCUTANEOUS FLAP

为了观察面动脉肌皮瓣修复口底缺损的临床效果，１９９１年～１９９７年，应用面动脉肌皮瓣２１个，修复口底及邻近组织器官缺损２１例。皮瓣面积最小８ｃｍ×３．４ｃｍ，最大１２．１ｃｍ×５．４ｃｍ。皮瓣转移后供区直接拉拢缝合。术后１９例皮瓣完全成活，２例有局部尖端坏死，换药治愈。详细介绍了面动脉肌皮瓣的应用解剖、设计与操作要点，对该皮瓣的优点和术后面部畸形的预防进行了讨论。认为，面动脉肌皮瓣是修复口底缺损的理想方法。

In order to study the clinical efficacy of facial artery musculocutaneous flap on repairing the defect of the floor of mouth, 21 patients had received this type of treatment from 1991 to 1997. The size of the flaps ranged from 8.0×3.4cm to 12.1×5.4cm and the average age of these patients was 59.5 years old. The donor site was closed directly. Nineteen flaps survived completely, while necrosis occurred at the apex of the other 2 flaps, which healed by ordinary managenent. The applied anatomy of the flap and the design and the main points of the operation were reported in details. The advantage of the flap and the prevention of facial malformation following operation were discussed. The conclusion was that this type of flap was ideal for reconstruction of the defects of floor of the mouth.
