title: Unilateral condylar bone deformity and slope of articular eminence related to mandibular asymmetry.
abstract: The present study was undertaken to investigate the correlation between condylar position, articular eminence morphology, and mandibular deviation using helical CT in a group of 22 female subjects (mean age 19.2+/-5.3 years) with mandibular deviation. There was a significant difference in the angles of the posterior-slope of the articular eminence (PSA) between the deviated (44.27+/-10.29 degrees) and non-deviated (42.50+/-9.90 degrees) sides. Mandibular deviation also correlated significantly with both medial joint space (r=0.581) and the PSA (r=0.653). A significant negative correlation was also found between mandibular deviation and the anterior/posterior joint space ratio (r=-0.450). These results demonstrated that patients with mandibular deviation possibly show asymmetries not only in their glenoid fossa morphology but also in their condylar position.
