唇部缺失后的修复方法很多。但同时重建上下唇缺失的情况很少见。本文作者经治的一例2岁小女孩,因坏疽性口炎致上下唇同时缺失,试图用双侧鼻唇部皮瓣重建上唇失败后,改用颏部管状皮瓣同时重建上下唇,收到良好效果。 手术过程 在下颌体下方用两个桥体托起一块长条状颏部皮瓣,两周后移去桥体,缝合做成管状皮瓣。3周后,皮瓣中央对位到下切牙下方的缺损中心。再过4周,从皮瓣中央已能提供足够血供,切断两个蒂,但不对位到唇部,该时期是皮瓣能否存活的关键时期。3周后清除口周瘢痕组织,将皮瓣沿口周缝合,两蒂在鼻下
There are many ways to repair the missing lips. However, it is rare to reconstruct the missing upper and lower lip. The author of this article, a 2-year-old girl, due to gangrenous stomatitis caused by the upper and lower lips at the same time missing, trying to use the bilateral nasolabial flap to reconstruct the upper lip fails, use the chin tubular flap while reconstructing the upper and lower lip, received Good effect.

Three weeks later, the perioral scar tissue was removed, and the flap was sutured along the perioccipital region. The two pedicles were under the nose
