摘要：

目的：探讨逆行双叶前臂桡侧皮瓣修复口腔癌术后贯通性薄型组织缺损的可行性和应用价值。方法：对8例口腔癌术后贯通性薄型组织缺损采用逆行双叶前臂桡侧皮瓣进行修复，并对皮瓣成活情况、修复效果等进行观察。结果：应用8例皮瓣有效修复了缺损，其中1例皮瓣出现周边瘘管，换药后愈合，1例因下颌骨下缘卡压，导致皮瓣部分坏死，经过换药后逐渐愈合。皮瓣修复后外形较佳，供区瘢痕隐蔽，美观性好。结论：利用逆行双叶前臂桡侧皮瓣修复口腔癌术后贯通性薄型组织缺损是较好的方案。

Abstract:

Objective: To investigate the feasibility and application value of reconstructing penetrating thin tissue defects after oral cancer ablative surgery with reverse bilobed radial forearm flap. Method: A total of 8 cases with penetrating thin tissue defects after oral cancer surgery were repaired by reverse bilobed radial forearm flap. Flap survival situation and repair effects were observed. Result: All of the 8 flaps survived, of which 1 flap had peripheral fistula, which was healed after dressing change, and 1 flap showed partially necrosis due to compression to the lower edge of the mandible, which was gradually healed after dressing change. After the flap repair, the shape of the defect area was better. The scars in the donor site were concealed with good aesthetic performance. Conclusion: Reconstruction of penetrating thin tissue defects after oral cancer ablative surgery with reverse bilobed radial forearm flap is a feasible and effective method.
