Abstract: Objective　To analyze the method of ORIF for different types of mandibular condyle fracture. Methods　From January 2011 to March 2014, 46 adult patients with condyle fractures of the mandible were studied. ALL the patients undergone the ORIF of mandibular condyle fractures and were followed up weekly for 3 weeks and then at 2, 3 and 6 months after surgery. The patients accepted CBCT examination 1 week and 3months after operation. Clinical examinations including mouth opening, deviation on mouth opening, occlusion, function of facial nerves, frey syndrome, screw loosing and salivary fistula were conducted. And the satisfaction degree of the patients was checked. Result　No screw loosing salivary fistula and frey syndrome were found in the follow-up patients; facial nerve dysfunction was found in 7 patients (23.91%) all in condyle head and subcondyle fracture group. Facial nerve dysfunction in condyle neck group was significantly lower than the other two groups（p<0.05）.Mmouth opening outcome in all groups significantly improved over time after surgery（p<0.05）.Of the 46 condyle fractures that were associated with deviation on mouth opening were those of condyle head fracture 11 (23.91%), followed by subcondyle fracture 5 (10.87%) and condyle neck fracture 4 (8.70%). 37 of 46 patients expressed high satisfaction degree for the treatment. Conclusion　Appropriate incisions, fixation methods and operations should be chosen for different types of mandibular condyle fractures. For condyle head fracture, it will be better to be fixed with titanium screws and the lateral pterygiod muscle should be remain attached to the fractured medial segment. The patients got good mouth opening and occlusion and gave high satisfy degree for the treatment..
