目的详细阐明前臂尺侧游离皮瓣的应用解剖、制做技术及在口腔颌面外科的应用。方法对３０例前臂尺侧游离皮瓣修复口腔颌面部缺损的病例，进行了临床回顾性分析。结果前臂尺侧游离皮瓣具有较薄、柔软、弹性好且与面部的色泽相近的优点。它血管蒂长、口径较粗，适合与口腔颌面部的血管吻合。与前臂桡侧游离皮瓣相比，它的供区疤痕相对隐蔽，本组成功率为９０％。主要不足是损失了前臂一条主要供应血管一尺动脉。结论当某种原因，前臂桡侧游离皮瓣不能切取，如桡动脉阻塞，近期曾行桡部静脉穿刺或经该静脉行化疗，这时前臂尺侧游离皮瓣不失为口腔颌面部软组织缺损游离修复的最佳选择。
Objective To clarify the application anatomy of the ulnar free forearm forearm flap, its technique and its application in oral and maxillofacial surgery. Methods A retrospective analysis was performed on 30 cases of oral maxillofacial defect repaired with ulnar forearm forearm flap. Results Forearm ulnar free flap has the advantages of thin, soft, elastic and similar to the facial color. It is a long pedicel, caliber thick, suitable for oral and maxillofacial vascular anastomosis. Compared with the radial forearm free flap, its donor area scar relatively hidden, the composition of the power was 90%. The main disadvantage is the loss of one of the main supply vessels in the forearm. Conclusion For some reason, the free radial forearm flaps can not be removed, such as radial artery occlusion, the recent radial vein puncture or by the vein chemotherapy, then forearm ulnar free flap remains the oral and maxillofacial soft tissue defect free The best choice for repair.
