Condylar change after upward and forward rotation of the maxillomandibular complex.

Tomographic radiographs of 44 healthy temporomandibular joints in 22 patients undergoing large upward and forward rotations of the maxillomandibular complex were evaluated. Immediate postsurgery results showed decreases in all areas of the joint space. Long-term results showed a decrease in the superior and posterior regions, 14.8% and 19.7%, with no significant change anteriorly. Simple and multiple regression analysis did not show any relationship with age, gender, or degree of change in the decrease of the occlusal plane angle, to the temporomandibular joint changes described. Some condylar remodeling was noted.
