OBJECTIVE
To investigate the temporomandibular joint (TMJ) function of the condylar hyperplasia patients after condylectomy.
METHODS
Twelve patients with condylar hyperplasia were included in this study. Before and after condylectomy, they were examined and the Fricton' s Craniomandibular Index (CMI) was calculated to assess the functional disorder of TMJ.
RESULTS
(1) The facial asymmetry was improved after condylectomy. The morphological symmetry of the bilateral condyle and ramus was displayed by X-ray examinations. There was new cortex formed on the surface of the operated condyle. (2) The TMJ function was improved in terms of Fricton's DI and CMI, which decreased from 0.131 and 0.066 to 0.042 and 0.021 respectively (P < 0.05).
CONCLUSIONS
Condylectomy is an effective method to remedy facial asymmetry and, at the same time, improve the TMJ function of the condylar hyperplasia patients.
目的
探讨髁突切除术对髁突增生患者颞下颌关节（TMJ）功能的影响。
方法
本研究纳入12例髁突增生患者。在髁突切除术前、后对患者进行检查，并计算Fricton颅下颌指数（CMI）以评估TMJ的功能紊乱情况。
结果
（1）髁突切除术后面部不对称情况得到改善。X线检查显示双侧髁突及下颌支形态对称。手术侧髁突表面有新皮质形成。（2）从Fricton的功能紊乱指数（DI）和CMI来看，TMJ功能得到改善，DI和CMI分别从0.131和0.066降至0.042和0.021（P < 0.05）。
结论
髁突切除术是矫正面部不对称并同时改善髁突增生患者TMJ功能的有效方法。
