Reconstruction of the oral commissure following electrical burn injury is a challenging problem. The commissure is a thin, delicate structure that is highly mobile and essential to normal facial appearance and expression. When there is full-thickness destruction of vermilion, mucosa, skin, and orbicularis muscle, the resulting contracture alters adjacent structures, displaces the commissure, and distorts facial animation. Utilizing a composite ventral tongue flap of mucosa and muscle in the reconstruction of the commissure permits effective release of scar contracture and replaces destroyed mucosa and muscle bulk. Remaining structures can be returned to their normal location, and the three-dimensional contours of the oral commissure can be better restored. The use of this flap in 21 patients has resulted in improved mobility, more normal facial expression, and more consistent results in the reconstruction of a wide range of commissure deformities.
电烧伤后口角的重建是一个具有挑战性的问题。口角是一个薄而精细的结构,高度可动,对正常面部外观和表情至关重要。当唇红、黏膜、皮肤和口轮匝肌发生全层破坏时,由此产生的挛缩会改变相邻结构,使口角移位,并扭曲面部表情。在口角重建中使用黏膜和肌肉复合腹侧舌瓣可有效松解瘢痕挛缩,并替代被破坏的黏膜和肌肉组织。剩余结构可恢复到正常位置,口角的三维轮廓能得到更好的修复。在21例患者中使用该皮瓣,改善了活动度,使面部表情更自然,在各种口角畸形的重建中取得了更一致的效果。
