A 26-year, 9-month-old woman had chief complaints of mandibular protrusion and facial asymmetry. Extraoral examination indicated mandibular deviation to the left side, severe facial asymmetry, and a concave profile. Because the patient had a vertical maxillary height difference and an occlusal plane cant together with maxillary retrusion, a differential downgraft and advancement surgery with Lefort I osteotomy was planned. To correct the facial asymmetry and mandibular protrusion, concurrent bilateral sagittal split osteotomy was performed. Double-jaw surgical procedures, including maxillary and mandibular movements, are effective in correcting severe facial asymmetry and skeletal Class III malocclusion.
一名26岁9个月大的女性主要抱怨下颌前突和面部不对称。口腔外检查显示下颌向左偏斜、严重面部不对称以及面部轮廓凹陷。由于患者存在垂直向的上颌高度差异、咬合平面倾斜以及上颌后缩,计划采用Lefort I型截骨术进行差异性降移和前徙手术。为了纠正面部不对称和下颌前突,同时进行了双侧矢状劈开截骨术。包括上颌和下颌移动的双颌外科手术对于纠正严重面部不对称和骨性III类错牙合畸形有效。
