摘要:

对1例因关节强直导致的偏颌畸形患者行下颌骨体牵张成骨器植入术,术后1周开始牵张右侧下颌骨,牵张20 d后右侧下颌升支及下颌体高度明显增加,牵张器维持4个月,右侧上颌骨自动向下生长,上下颌咬合关系恢复正常,取出下颌牵张成骨器,在牵张成骨新骨上植入MEDPOR假体并行颏成形术。手术完成后患者颜面不对称及畸形咬合关系均得到明显改善。

Abstract:

A facial asymmetry patient caused by temporomandibular joint ankylosis was operated by putting a distraction osteogenesis(DO)-appliance. One week after surgery, the right mandible was distracted. Twenty days after distraction, the height of right mandibular ramus and body increased obviously. Four months after retain of DO-appliance, the right maxilla down-grew automatically and the occluding relation recovered to normal. The DO-appliance was taken out. MEDPOR prosthesis was imbedded in new bone and genioplasty was operated. The facial asymmetry and abnormal occluding relation of the patient were improved obviously.

Key words: distraction osteogenesis, temporomandibular joint ankylosis, facial asymmetry malformation
