A series of 25 extreme Angle class III cases who were operated on by a combined advancement of the maxilla after Le Fort I osteotomy and retropositioning of the mandible after sagittal splitting of the rami was evaluated clinically and radiologically (mean 4 years) after the osteotomies. A very limited number of early postoperative complications and problems were found. A late follow up 22 cases showed a good or even excellent aesthetic result. Occlusion had remained absolutely stable in 17 cases, while in 4 a partial relapse to an edge to edge position of the incisors had occurred. Cephalometric X-ray analysis showed that only in one case had the maxilla move slightly back-wards, while in 5 a small relapse of the mandibular movement was seen. It is therefore concluded from this study, that a combined osteotomy of upper and lower jaw is the treatment of choice for extreme Angle class III deformities. The low complication rate, the enormous aesthetic gain and the few problems and small partial relapses seen at late follow up lead us to recommend this procedure strongly.
对25例严重安氏III类病例进行了评估,这些病例接受了Le Fort I截骨术后上颌骨的联合前徙和下颌升支矢状劈开术后下颌骨的后退手术。在截骨术后进行了临床和放射学评估(平均4年)。发现术后早期并发症和问题数量非常有限。对22例患者的后期随访显示出良好甚至优异的美学效果。17例患者的咬合保持绝对稳定,而4例患者的切牙出现了部分复发至边缘对边缘的位置。头影测量X线分析显示,仅1例上颌骨稍有向后移动,5例可见下颌运动有小的复发。因此,本研究得出结论,上下颌联合截骨术是治疗严重安氏III类畸形的首选方法。低并发症发生率、巨大的美学改善以及后期随访中出现的问题较少和部分复发较小,使我们强烈推荐该手术。
