摘　　要：目的探讨口内入路下颌角弧形截骨术对矫正重度下颌角肥大的疗效。方法应用口内入路下颌角弧形截骨术对20例重度下颌角肥大患者进行矫正,通过X线头影测量,比较术前术后数据变化及容貌改变来评价疗效。结果术前面下部宽度12.221±0.765cm,术后面下部宽度10.797±0.688cm;术前下颌角角度111.209±7.946°,术后下颌角角度129.491±6.277°。手术前后比较有明显差异,术后数据接近正常人群。所有患者容貌较术前有明显改观,未出现下颌骨骨折,下齿槽神经损伤。结论针对重度下颌角肥大患者采用口内入路下颌角弧形截骨术,结合良好术前设计截骨线,可以有效矫正下颌角肥大,取得良好效果。Objective To study the effect of intra oral arc osteotomy of mandible for correcting severe prominent mandibular angle. Methods Intra-oral arc osteotomy of mandible was performed in 20 cases with severe prominent mandibular angel. The width of the lower face and mandibular angle were evaluated by X-ray before and after operation. Results Before operation, mandibular angle was 111.209±7.946 and the width of the lower face was 12.221±0.765 cm. After operation, mandibular angle was 129.491±6.277 and the width of lower face was 10.797±0.688 cm. All patients were satisfied with the contours. No severe complications such as fracture of mandible or damage of inferior alveolar nerve are observed. Conclusion Intra oral arc osteotomy of mandibular with design the extent of osteotomy was more effective mothod for correcting prominent severe mandibular angle.
