带皮岛游离腓骨骨皮瓣修复颌面部缺损

目的:探讨游离腓骨骨皮瓣皮岛在颌面部缺损修复中的作用及可靠性。方法:对55 例携带皮岛的游离腓骨骨皮瓣,分析所采用皮岛的设计、大小、修复部位及存活情况。结果:55 例游离腓骨骨皮瓣共携带皮岛57 块,其中37 块由1 个穿支供血,18 块由2 个穿支供血,2 块由3 个穿支供血。57 块皮岛中,用于口内缺损修复28 块,口外缺损修复7 块,口内和口外软修复1 块,面部软组织充填2 块,单纯用于游离腓骨骨皮瓣术后血供监测19 块。55 例腓骨瓣中,除1 例因静脉血栓经抢救无效后去除外,其余的54 例56 块皮岛均获得100 %成活。结论:游离腓骨骨皮瓣皮岛的血供安全可靠,其在颌面部缺损的修复中具有很大的灵活性,除软组织缺损的修复外,还可以作为游离腓骨瓣术后的观察窗,用于腓骨瓣血供的监测。

The Effectiveness and Reliability of Skin Paddles of Free Fibula Flaps in Reconstruction of Maxillofacial Defects

Objective:The paper reviewed the effectiveness and reliability of skin paddles of free fibula flaps in the reconstruction of maxillofacial defects.Methods:Fifty_five consecutive free fibula osteocutaneous flap transfers performed from June 21, 1999 to October 31, 2000 were reviewed. The skin paddles of each flap were analyzed in terms of surgical design, blood supply, size, reconstruction location, and survival.Results:Fifty_seven skin paddles were used for the 55 free fibula flaps (double skin paddles for 2 flaps), 37 were nurtured by one perforator, 18 by two and two by 3 perforators. Twenty_eight skin paddles were used for intraoral reconstruction, 7 for extraoral reconstruction, 1 for both intraoral and extraoral reconstruction, 2 for soft tissue augmentation, and the remaining 19 were simply used as window for monitoring the blood flow of fibula flap. One free fibula flap with one skin paddle was lost because of venous thrombosis, and the other 54 flaps survived completely, with 100% survival of 56 skin paddles.Conclusion:The skin paddle of free fibula flap is safe and reliable. It can be used for all kinds of soft tissue reconstruction, as well as window for monitoring the blood flow of fibula flap after operation.
