Radial forearm free flap reconstruction for head and neck cancer is very common, and it is widely considered a workhorse flap. Although this flap has a relatively reliable anatomy, surgeons need to be aware of possible anatomical variations and how to deal with them. This paper presents the cases of two patients who underwent oral reconstruction, in whom anomalies of the radial artery were identified while raising a radial forearm free flap. Case 1 demonstrates the dominant branch of the radial artery joining the common interosseous artery approximately 9 cm from the first wrist crease. Case 2 demonstrates abnormal distal branching of the radial artery approximately 4 cm from the first wrist crease. Reconstruction with the flap was successful in both cases. A literature review of reported anomalies of the radial artery is presented, and how to deal with such vascular anomalies is discussed.
前臂桡侧游离皮瓣重建用于头颈部癌症非常常见，被广泛认为是一种可靠的皮瓣。尽管该皮瓣具有相对可靠的解剖结构，但外科医生需要注意可能存在的解剖变异，并知道如何处理这些变异。本文报告了 2 例接受口腔重建的患者，在游离前臂桡侧皮瓣时发现桡动脉存在异常。病例 1 显示，桡动脉的优势分支在距离第一腕横纹约 9cm 处与骨间总动脉相连。病例 2 显示桡动脉在距离第一腕横纹约 4cm 处出现异常的远端分支。在这两种情况下，皮瓣重建均获得成功。本文还对已报道的桡动脉异常进行了文献回顾，并讨论了如何处理这些血管异常。
