对26例患者行矢状劈开截骨术后11--53个月的影像学表现进行了研究。在75%的病例中，与治疗前值相比，下颌角增加。这种差异具有统计学意义。在70%的病例中，角度增加了1- 10度。在25%的患者中，角度没有变化或减小。发现下颌支的前后宽度减小;当下颌角增大时，发现广泛的形态学变化。这些术后条件必须视为不满意，应考虑修改矢状劈开截骨术技术，例如EPKER 4所提倡的。
The radiological appearance of 26 patients was studied 11--53 months postoperatively following sagittal split osteotomy. In 75% of the cases examined an increase in the mandibular angle could be noted compared to pretreatment values. This differences was statistically significant. In 70% of the cases the angle increased by 1--10 degrees. In 25% there was no change or reduction in the angle. The antero-posterior width of the rami was found to decrease; when this was combined with an increase in the mandibular angle, extensive morphological changes were found. These postoperative conditions must be regarded as unsatisfactory and a modification of the technique of sagittal split osteotomy should be considered as for example advocated by EPKER4.
