PURPOSE
To evaluate the clinical effect of joint reconstruction by using autogenous coronoid process graft to treat temporomandibular joint(TMJ) ankylosis.
METHODS
Nine cases of TMJ ankylosis from September 2008 to September 2010 were surgically treated by joint reconstruction with autogenous coronoid process graft, using autogenous articular disc or prosthodontic membrane as interpositional material. Mouth opening, occlusion and cone beam CT(CBCT) were used for evaluation before and after surgery.
RESULTS
Satisfactory mouth opening was achieved in all patients and no one got occlusal changes or reankylosis during follow-up. CBCT showed that coronoid process graft reached bone union with the ramus and turned to be round.
CONCLUSIONS
It is effective to cure TMJ ankylosis through joint reconstruction with autogenous coronoid process graft.
目的
评估采用自体喙突移植进行关节重建治疗颞下颌关节（TMJ）强直的临床效果。
方法
对2008年9月至2010年9月的9例TMJ强直患者采用自体喙突移植进行关节重建手术治疗，以自体关节盘或修复膜作为植入材料。术前及术后采用开口度、咬合情况及锥形束CT（CBCT）进行评估。
结果
所有患者均获得满意的开口度，随访期间无患者出现咬合改变或再次强直。CBCT显示喙突移植与下颌支达到骨愈合且形态变圆。
结论
采用自体喙突移植进行关节重建治疗TMJ强直是有效的。
