Fourteen patients, diagnosed as cases of apertognathism, were subjected to ostectomy in the premolar or molar region on both sides. The operations were made with an intraoral approach in the premolar region anterior to the molar foramen and extraorally in the molar region. The mandibular segments were immobilized by cap-splints after the operations. A follow up, clinically and roentgenologically, was made after the splints had been removed and, in addition, one and five years later. The aesthetic as well as the functional results of the operations were very good. Only minor changes in the occlusion occurred during the follow up period. In a few patients minor unilateral decreases of sensibility were observed. The late results of the operations must therefore be regarded as good.
14名被诊断为牙关紧闭症的患者在双侧前磨牙或磨牙区接受了截骨术。手术在磨牙孔前方的前磨牙区采用口内入路，在磨牙区采用口外入路。术后用帽式夹板固定下颌骨段。在拆除夹板后，以及术后1年和5年进行了临床和X线随访。手术的美学和功能效果都非常好。随访期间咬合仅有轻微变化。少数患者观察到轻微的单侧感觉减退。因此，手术的远期效果良好。
