Purpose: To analyze the main causes of temporomandibular joint (TMJ) ankylosis due to condylar fracture in adults through retrospective study.Methods: History and CT scans of patients diagnosed with ankylosis caused by mandibular condyle fracture treated close were reviewed between 2010 to 2012 in our department.According to the relationship between the stump of the ramus and TMJ fossa, we divided condylar fractures into 3 grades: grade 0, in which the ramus stump is in the fossa with no contact to it; grade 1, in which the stump of the ramus is in the fossa with attach to it; and grade 2, in which the stump of the ramus is laterally displaced out of the fossa.Other factors like the type of condylar fracture, the displacement of the fractured fragment, the position of the disc and the concomitant mandibular fractures were also analyzed for ankylosis development.
