Condylar resorption after orthognathic surgery. Evaluation of treatment in 8 patients.
Several articles have been published on the subject of condylar resorption as a complication of orthognathic surgery. However, since there is little reference to treatment, the frequency of this phenomenon and the results of therapy are evaluated in a retrospective study. 8 patients out of a group of 329 who underwent sagittal split osteotomy in a 10-year period (251 bilateral, 73 Le Fort I + bilateral and 5 unilateral), were treated actively following the development of condylar resorption. 4 patients were operated upon a second time while others underwent occlusal rehabilitation. The results for the patients who underwent revisional surgery were unsatisfactory, with poor aesthetics and occlusal stability. The patients treated with an occlusal splint (+/- orthodontics and/or prosthetic therapy) had a functional occlusion and tolerable temporo-mandibular-joint complaints.
