MRI and clinical findings of posterior disk displacement in the temporomandibular joint. Abstract Text:

OBJECTIVE: The objective of this study was to evaluate the magnetic resonance imaging and clinical findings of patients with posterior disk displacement in the temporomandibular joint. STUDY DESIGN: Magnetic resonance and clinical findings of 62 temporomandibular joints (44 patients) with posterior disk displacement were retrospectively analyzed. RESULTS: According to the criteria proposed by Westesson et al., 52 temporomandibular joints (84%) were the thin flat disk type and the remaining 10 (16%) were the perforated disk type. Fifteen temporomandibular joints (24%) had a history of luxation. Clicking was observed in 26 temporomandibular joints (42%), all of which were the thin flat disk type (chi-square test, P < .01). Pain was observed in 19% of patients with the thin flat disk type and 60% of those with the perforated disk type (P < .05). CONCLUSIONS: Magnetic resonance imaging could clearly reveal the details of posterior disk displacement in the temporomandibular joint. The clinical findings were dissimilar between the thin flat and the perforated disk type.
