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.
