摘　　要：目的探讨牵引成骨技术在颞下颌关节强直治疗中的应用。方法应用内置式牵引器治疗8例单侧颞下颌关节强直患者,患侧升支区制备一个1.5～2.0cm颊舌向等宽的骨间隙,并去除喙突,恢复开口度,升支后缘方块截骨,截骨块保留翼内肌附着,与下颌骨间安装牵引器,术后采用升支牵引成骨术,每日牵引1mm,分2次完成,重建颞下颌关节结构及恢复颞下颌关节功能,并坚持开口训练18个月以上。结果经牵引成骨后,患者牵引间隙成骨良好,新形成的关节形态得到改建,升支高度延长1.2～2.1cm,开口度达到正常。结论牵引成骨是治疗颞下颌关节强直的有效方法。Objective To examine the effects of mandibular distraction osteogenesis in treatment of temporomandibular joint （TMJ） ankylosis. Methods Eight patients, aged from 16 to 45 years （ mean 28 years）, with unilateral TMJ ankylosis were treated by mandibular distraction osteogenesis. The bony mass was removed to create a 1.5- 2.0 cm space in the alkalosis area of the ramus. The transport disc was installed and connected with the mandible. The distraction began one week after operation at a rate of 0. 5mm at a time, 2 times a day. The patients underwent active mouth -opening training for at least 18 months. Results After distraction osteogenesis, new bone formation in distraction gaps accomplished, and the TMJ remodeled. The height of ramus increased by between 1.2-2. 1 cm. Postoperative maximal mouth opening reached 3.8-5.2 cm. Conclusion Distraction osteogenesis is an effective method in treatment of TMJ ankylosis.
