原发灶对侧面动脉黏膜肌皮瓣整复口腔颌面部缺损的临床应用研究

目的 采用原发灶对侧面动脉黏膜肌皮瓣整复舌及口底缺损，丰富口腔颌面部缺损的整复方法。方法 采用6例对侧面动脉黏膜肌皮瓣整复舌及口底肿瘤切除术后缺损。结果 6例原发灶对侧面动脉黏膜肌皮瓣均有足够的血管蒂到达对侧口底舌腹，皮瓣全部成活。所有患者术后均暂时出现面部紧张、张口受限障碍等并发症，3个月后好转，术后半年未见皮瓣缩小。结论 原发灶对侧面动脉黏膜肌皮瓣颜色与舌及口底颜色几乎完全一样，切取简单，成活率高，供区再次损伤畸形小，有望成为舌口底恶性肿瘤切除后即刻修复常规皮瓣。

Clinical application of primary tumor contralateral facial artery musculocutaneous flap to reconstruct oral and maxillofacial defects

Objective This study aims to explore the method that uses primary tumor contralateral facial artery musculocutaneous (FAMM) flap to reconstruct defects of the tongue and floor of mouth. Methods Six cases were selected for the use of primary tumor contralateral FAMM flap to reconstruct tongue and floor of mouth defects after tumor resection. Results The FAMM flap of the six cases had a long pedicle that could reach the contralateral tongue and floor of mouth. All flaps were intact until post-operation. All patients experienced post-operation complications, such as temporary facial tension and limited mouth opening, which improved after 3 months. Half a year later, the flaps still did not show signs of shrinking. Conclusion Features of the primary tumor contralateral FAMM flap include the tissue-like material provided for reconstructing tongue or floor of mouth defects, easy acquisition, and high survival rate with minimal donor site morbidity. As such, it is an ideal material for repairing tongue and floor of mouth defects.
