舌正中岛状瓣修复口底缺损

目的：总结应用舌正中岛状瓣修复口底缺损的经验。方法：5例中小型口底缺损患者采用舌正中岛状瓣修复重建。在舌背正中部位制备舌肌黏膜瓣，通过切开舌尖或舌组织隧道以岛状瓣的方式转移修复口底缺损。结果：5例患者术后舌瓣均成活良好，无舌瓣坏死，1例术后一侧舌尖部分坏死。术后随访3-6个月，患者发音及吞咽功能无明显异常。结论：舌正中岛状瓣是一种修复中小型口底缺损的好方法。

Median island tongue flap for reconstruction of the floor of mouth defects.

Objective： To explore the application of the median island tongue flap in the reconstruction of the floor of mouth defects. Method： This case series consists of 5 patients who were reconstructed with a median island myomucosal tongue flap for small and medium sized defects in the floor of mouth. This method involves the creation of a myomucosal is- land flap from the dorsal median portion of the tongue and transferring it to the floor of the mouth by incision of tongue tip a- long the midline or through tongue tunnel. Result： The procedures were successful in all patients. All flaps survived. There was no flap necrosis or loss. One patient had partial necrosis of the tip of the tongue. No remarkable disturbances of speech or deglutition were observed in all the patients. Conclusion： The median island tongue flap is a suitable reconstruction option for small and medium sized defects of the floor of mouth.
