OBJECTIVE
To asses the fate of the costochondral graft (CCG) used to stimulate mandibular growth in the management of Temporomandibular joint (TMJ) reconsrtuction in ankylosis-histologically.
MATERIALS AND METHODS
Ten patients who had undergone CCG grafting for TMJ ankylosis between 1994-2009 in the department of Oral & Maxillofacial Surgery, Tamil Nadu Govt Dental College and Hospital, Chennai and had come back with reankylosis, were surgically explored and the graft along with the ankylotic mass was excised and evaluated histologically. There is no documented human study and clinically it is not possible.
RESULTS
Histological evaluation revealed the presence of osseous tissue, fibrous tissue and osteocytes but no evidence of any chondroid tissue.
CONCLUSION
Our study showing the absence of chondroid tissue raises the question on the rationale of CCG in TMJ reconstruction when other interpositional gap arthroplasty can achieve a disease free joint.
目的
从组织学角度评估在颞下颌关节（TMJ）强直重建中用于刺激下颌生长的肋软骨移植（CCG）的转归。
材料与方法
20名于1994年至2009年间在金奈泰米尔纳德邦政府牙科学院及医院口腔颌面外科接受TMJ强直CCG移植手术且出现再次强直后回来复诊的患者，接受了手术探查，切除移植组织及强直块并进行组织学评估。尚无相关人体研究记录，且临床操作上也不可能进行。
结果
组织学评估显示存在骨组织、纤维组织和骨细胞，但未发现任何软骨样组织的证据。
结论
我们的研究显示不存在软骨样组织，这引发了一个问题，即在其他间隙关节成形术可实现无病关节的情况下，TMJ重建中使用CCG的理论依据是什么。
