腓肠内侧动脉穿支皮瓣修复颊癌术后缺损的初步应用

Application of Medial Sural Artery Perforator Flap in Repair of Defects After Buccal Carcinoma Ablation

目的探讨应用腓肠内侧动脉穿支皮瓣修复颊癌术后缺损的效果。方法 2011年至2014年,选取11例颊粘膜鳞状细胞癌患者,应用腓肠内侧动脉穿支皮瓣修复手术后缺损。皮瓣制备时采用改良式参考线,并借助于多普勒超声定位穿支血管。血管吻合操作均在放大镜或显微镜辅助下完成。结果 11例皮瓣全部存活,没有发生血管危象。颊部缺损得到修复。患者术后开口及咀嚼功能恢复良好,受区无明显并发症。所有患者供区切口愈合良好,无伤口开裂、感染及功能障碍等并发症,术后线状瘢痕较为隐蔽。结论腓肠内侧动脉穿支皮瓣是修复颊癌术后缺损的良好方法,值得推广应用。

Objective To explore the application of medial sural artery perforator flaps （MSPFs） in repair of defects following buecal cancer ablation. Methods From 2011 to 2014, 11 patients were included in this study. Eleven MSPFs were harvested to reconstruct defects caused by buceal carcinoma ablation. A modified reference line was used when harvesting the flap. Doppler ultrasound was used to localize perforators. Vascular anastomosis were completed under the magnifying glass or microscope. Results All the flaps healed without venous insufficiency. Buccal defects were repaired primarily. Opening of the month and mastieatory function were well recovered. No obvious complications were found in donor site. No infection, dysfunction of leg or wound dehiscence were found. Only a concealed postoperative linear scar was left. Conclusion The MSPFs can be a good candidate for the repair of defects of the maxillofaeial area after cancer ablation.
