Abstract: Objective　To explore the clinical features and treatment of condylar fractures. Methods　Clinical data including causes of injuries， treatment and efficacy of 179 patients with condylar fractures from 1990 to 2010 were retrospectively analyzed and compared. Results　92 of 179 patients were caused by traffic accidents(51.4%), and 76 cases had condylar neck fracture（42.3%）. 123 cases received conservative therapy and 56 cases received internal fixation surgical treatment from different approaches. The rate of cases who received conservative treatment in youth group was higher than that in adult group（P＜0.01）. Treatment methods of different fracture sites had significant differences（P＜0.01）. The treatment rate of condylar head fracture by conservative therapy was highest (92.06%). When the treatment of mandibular condylar fractures was combined with treatment of bone fractures on other sites, the treatment rate was higher than those not combined（P＜0.01）.Most of the cases acquired perferct occlusion after treatment. Limitation rate of mouth opening of double side condylar fracture cases increased significantly in early period（P＜0.01），which were recovered through functional exercise and reached over 3.0 cm one year later. Conclusions　Traffic accident is the primary risk factor of condylar fracture. Neck is the most frequent site of condylar fracture. Youth group mainly take conservative therapy. Cases combining fractures on other sites mostly choose surgicaltreatment. The angle of fracture end displacement in surgical treatment is more than 30 °, and vertical height of mandibular ramus reduce by more than 5 mm. It’s important for cases to have limitation of mouth opening less than 2 cm after conservative therapy.
