title: [Relation between anterior displacement of the temporomandibular joint disc and size of the condyle].
abstract: To elucidate the cause of anterior displacement of the disc, we evaluated the relation between anterior displacement and the size of the condyle from MR images in 301 patients (602 TMJs) with clinical diagnosis of internal derangement. We found that the size of condyles with anterior displacement of the disc was significantly smaller than that of condyles without anterior displacement. This result suggests that small condyles may give rise to anterior displacement of the disc.
