Osteoradionecrosis of the mandible is a serious complication following radiotherapy of head and neck cancers. A retrospective study of 20 reconstructions of mandibular defects due to osteoradionecrosis was performed. Various osseocutaneous free flaps were used: upper lateral arm (n = 5), radial forearm (n = 1), iliac crest (n = 4) and fibula (n = 7). Four grafts had a condylar prosthesis, and for seven grafts fixation was accomplished with a reconstruction plate. In three patients the mandibular defect was reconstructed using a bridging plate only. We defined a successful reconstruction as a graft or plate that did not need removal. Success was noted in 15 out of 20 patients, giving an overall success rate of 75%. For the free grafts alone (n = 17), successful reconstruction was achieved in 15 patients (88%). Two fibular grafts were lost owing to exposure and infection, as well as all three alloplastic reconstructions. Minor postoperative complications were observed in 11 patients (58%).
下颌骨放射性骨坏死是头颈部癌症放疗后的一种严重并发症。对20例因放射性骨坏死导致下颌骨缺损的修复病例进行了回顾性研究。使用了各种骨皮瓣:上臂外侧(n = 5)、桡骨前臂(n = 1)、髂嵴(n = 4)和腓骨(n = 7)。4例移植采用髁突假体,7例移植用重建钢板固定。3例患者仅使用桥接钢板重建下颌骨缺损。我们将成功的重建定义为无需取出的移植或钢板。20例患者中有15例成功,总体成功率为75%。仅就游离移植(n = 17)而言,15例患者(88%)实现了成功重建。2例腓骨移植因暴露和感染失败,所有3例异体材料重建均失败。11例患者(58%)出现轻微术后并发症。
