The excision of sick condyle was per formed in 6 cases. In 2 cases of unilateral mandibular macrognathia, the under edge of mandible was excised besides the excision of sick condyle. Results: All the patients have been followed up 1～2.5years, there is no relapse. Very good occlusion, occlusal plane and facial contour were achieved in 6 cases. Good results were achieved in 2 cases. Conclusion: The excision of sick condyle can satis fyingly correct lateral deviation of mandible caused by condylar disease. ......
