不同治疗方法在下颌骨缺损修复中的效果比较

目的分析三种常用的下颌骨缺损修复重建方法对下颌骨缺损修复的效果。方法对因肿瘤行下颌骨缺损修复重建的78例患者临床资料进行回顾性分析。结果78例患者中采用自体游离骨移植55例（70．5％），采用游离血管化骨肌瓣移植5例（6．4％），采用替代物植入18例（23．1％）。植入成功率分别为94％、100％、67％。结论对下颌骨缺损患者应根据根据个性化的原则选择不同的修复方法。单纯游离骨移植仍然是目前临床上最常用的下颌骨缺损修复方法之一；血管化骨肌瓣移植虽然成功率高，但由于费用高、创伤大等不利因素的限制，选择该术式的患者比例低；替代物植入因有排异反应，仅可作为补充方法。

Different treatment of mandibular defects comparison

Objective To analyze three commonly used methods of repair and reconstruction of mandibular defects on the effect of mandibular defects. Methods The tumor reconstruction of mandibular defects on 78 patients were retrospectively analyzed about the clinical data. Results 78 patients with autogenous free bone grafting 55 cases （70.5%） , with free vascularized bone flap transplantation in 5 patients （6.4%）, alternative implantation in 18 cases （23.1%）. Implant success rate was 94%, 100%, 67%. Conclusion The mandibular defects are personalized in accordance with the principle of selection according to different repair methods. Free bone graft alone is still the most commonly used clinical mandibular defect repair methods ; despitevascularized bone flap transplantation has a high success rate, hut because of the high cost and large trauma adverse factors, selection of the surgical patients ratio is low; due to rejection alternative implant only as a supplementary method.
