下颌骨缺损重建植入材料的回顾性研究

Retrospective study on the materials used in the reconstructoin of mandibular defects

目的 :通过对 3 0年来我院经治患者随访结果进行分析 ,评价下颌骨缺损重建中不同材料、方法和不同缺损部位的临床效果。方法 :对武汉大学口腔医院近 3 0年下颌骨缺损修复患者 467例进行随访。结果 :回访 3 95例 (84.6% ) ,男 2 3 8例 ,女 15 7例 ,年龄 4～ 72岁。 3 95例患者中植入非生物材料者 10 1例 ,骨移植者 2 94例。骨移植组骨生长状况明显优于非生物材料组 (P <0 .0 1)。面部外形和张口度的恢复效果依次为 :冷冻自体病变骨与髂骨复合移植 (FALB IBCG)优于单纯髂骨移植 ,冷冻自体骨、肋骨移植优于羟基磷灰石、有机玻璃。结论 :自体骨移植成骨快 ,FALB IBCG面部外形恢复好 。

objective: To evaluate the clinical effect of various materials used in the reconstruction of mandibular defects retrospectively. Methods: 467 patients with mandibular defects were treated with various implantation materials during last 30 years and 395 of them were followed up.Results: 217 were satisfied with their mouth opening, occlusion and maxillofacial contour after sugery, 189 of them had bone transplanation and 28 had non biomateria transplantaion; 91 were partly satisfied, 72 of them had bone trasplantation and 19 had non biomateria; 87 were not satisfied, 11 of them had bone trasplantation and 76 had non biomaterial. Conclusion: Bone especially auto bone transplantation is more effective than non biomaterial in the reconstruction of mandibular deffects.
