游离前臂皮瓣与钛网联合修复上颌骨缺损

目的观察游离前臂皮瓣与钛网联合修复上颌骨缺损的临床效果.方法 2002年1月～2002年11月,对3例上颌牙龈癌、1例腭部黏液表皮样癌和1例上颌窦癌分别行上颌骨次全切除或全切除术,术后遗留上颌骨缺损用 4 cm×5 cm～6 cm×7 cm大小的游离前臂皮瓣与钛网联合修复.术后通过临床检查、CT和鼻内窥镜检查评价其效果. 结果 5例患者均获5～15个月随访,无肿瘤复发,移植皮瓣全部成活,面部外形及牙槽突和腭部形态恢复良好,鼻腔面钛网被软组织覆盖,语言和吞咽功能恢复良好.其中2例已行可摘局部义齿修复. 结论游离前臂皮瓣和钛网联合应用是上颌骨缺损较理想的修复方法.

REPAIR OF MAXILLARY DEFECTS BY FREE FOREARM FLAP AND TITANIUM MESH

OBJECTIVE: To investigate the clinical effect of free forearm flap and titanium mesh in repairing maxillary defects. METHODS: From January 2002 to November 2002, partial maxillectomy or maxillectomy were performed in 3 patients with maxillary gingival carcinoma, in 1 patient with palatine mucoepicermoid carcinoma and in 1 patient with maxillary sinus carcinoma. Maxillary defects were reconstructed with free forearm flaps ranging from 4 cm x 5 cm to 6 cm x 7 cm and titanium mesh. The effect was estimated by clinical examination, CT and nasopharyngoscope. RESULTS: Five cases were followed up 5-15 months. All the flaps were alive. Facial, alveolar process and palatal contours were restored well. Epithelium was found on the nostril surface of the titanium mesh. The functions of speech and chew were restored well. CONCLUSION: A combination of the free forearm flap and titanium mesh is an ideal method in reconstruction of maxillary defects.
