摘　　要：目的　评价应用口外弓加面具对唇腭裂继发骨性反牙合畸形进行早期阻断性治疗后 ,下颌骨髁突位置的变化。方法　对 8例患者治疗前和治疗 6个月的薛氏位片进行分析 ,比较颞下颌关节 (TMJ)前、上、后间隙的宽度。结果　治疗前后双侧TMJ的 3个间隙均无明显改变 (P >0 .0 5 )。结论　应用口外弓加面具作上颌骨前牵引后 ,未发现髁突位置的明显改变。Objective To evaluate the changes of the position of the mandibular condyle in cleft lip and palate patients with secondary bony cross-bite deformity after early orthodontic treatment with extraoral bow and facial mask.Methods The TMJ topograph 6 months before and after treatment was investigated in 8 patients.The width of the anterior,superior and posterior space of the TMJ was compared prior to and post treatment.Results The results showed that there was no significant difference in the width of the three spaces of the TMJ before and after treatment.Conclusion The positon of the mandibular condyle had no significant change after maxillary anterior distraction with extraoral bow and facial mask.
