目的矫治下颌角肥大有多种式术,但单一式术往往很难达到满意的矫治效果,探讨下颌角截骨术与下颌角外板矢状劈开术联合应用的治疗方法的疗效.方法 21例下颌角肥大患者,于完成术前检查与分析后,在全身麻醉下应用口内入路行双侧下颌角外板矢状劈除后同时行下颌角弧线截骨术,术后观察两侧下颌角间距变化.结果 21例伤口均愈合良好,无感染、血肿等并发症发生.经7个月至1年的随访,双下颌角间距明显缩小,下面部宽大畸形显著改善,下颌角部曲线圆滑,形态自然,效果满意.结论联合术式不仅有效地纠正了面下部过宽,使整个面部轮廓变得圆滑、柔美,方形面型得到满意改善,值得推广应用.

Objective Several surgical procedures are available for treatment the prominent mandibular angle. But in some patients, only one procedure is not likely to obtain satisfactory results. This study was to evaluate the effect of curved osteotomy combined with sagittal splitting osteotomy of the mandibular angle by an intraoral approach for treatment the broad lower face. Methods 21 patients with broad lower face were treated with mandibular angle osteotomy plus mandibular angle splitting osteotomy under general aesthesia by intraoral approach. Changes of the distance between the mandibular angles were observed during follow up phase. Questionnaires were used to assess the patents level of satisfaction after operation. Results All the wounds healed without complications of bleeding and infection. After 7 months to 12 months follow up, the distance between the mandibular angles was effectively reduced, the deformity of broad lower face were improved markedly, the curve of the mandibular angle was smooth and the shape was natural. Conclusion This method is worthy to be applied widely because of the good result with effective reduction of the width of the lower face, smooth and gentle outline of the face.
