摘　　要：目的通过对成人骨性Ⅲ类偏颌畸形患者的颏部形态结构特征及对称性进行探索,研究偏斜患者颏部形态及代偿情况。方法选择66例骨性Ⅲ类患者,分为偏斜组(33例)及非偏斜组(33例),拍摄CBCT并进行头影测量,比较颏部形态对称性。结果成人骨性Ⅲ类偏颌畸形患者下颌左偏趋势更加明显,颏孔位于下颌骨中央,颏部单位长度及下颌骨倾斜度存在不对称,偏斜侧较偏斜对称颏部单位长度减小、倾斜度减小。结论成人骨性Ⅲ类偏颌畸形患者颏部存在不对称及代偿。Objective To evaluate the chin morphology and compensation,by analyzing the morphological and structural characteristics and symmetry of chin in adult patients with skeletal Class III mandibular deviation.Methods Sixty-six patients with skeletal Class III were selected and divided into deviation group(n=33)and control group(n=33).Morphology and symmetry of chin were evaluated based on CBCT examination data.Results The left deviation of mandible is more obvious in adult patients with skeletal Class III mandibular deviation.The mental foramen was located in the center of the mandible.The deviated side had smaller chin unit length and inclination than the nondeviated side(P<0.05).Conclusion There were asymmetry and compensation in the chin of adult patients with type III mandibular deviation.
