In a study of 67 cases the authors have investigated clinically and radiologically the long term results (5 years and over) of the sagittal split technique (Obwegeser 1955, 1957). Although 95% of the patients are satisfied, 60% have some impairment of sensation in the lower lip. This however goes unnoticed in 40% of these cases. The temporo-mandibular joint does not appear to be affected. 73% of the patients have excellent or good occlusion, while 18% have an unsatisfactory anterior occlusion due to some degree of relapse. The remaining 9% have poor occlusion without sign of relapse. A statistical analysis of the teleradiographs reveals that relapse is due to a rotation of the body of the mandible. Since several changes in technique have meanwhile been adopted, this paper will be followed by an analysis of the more recent cases.
在一项针对67例患者的研究中，作者对矢状劈开术（Obwegeser，1955年、1957年）的长期效果（5年及以上）进行了临床和放射学调查。尽管95%的患者感到满意，但60%的患者下唇感觉有一定程度的受损。然而，其中40%的病例未察觉到这种情况。颞下颌关节似乎未受影响。73%的患者咬合良好或极佳，而18%的患者由于某种程度的复发导致前牙咬合不满意。其余9%的患者咬合不佳但无复发迹象。对远距离X线片的统计分析显示，复发是由于下颌体的旋转。由于在此期间已经采用了一些技术改进，本文之后将对近期病例进行分析。
