This case report describes the successful treatment of an adult patient with idiopathic condylar resorption and Class II skeletal open bite malocclusion and temporomandibular joint disorder. A segmental Le Fort I bilateral osteotomy, ramus increasing length inverted L-osteotomy, and genioplasty combined with orthodontic treatment were performed. The treatment plan and surgery was aided by three-dimensional medical modeling, and we managed to resolve functional, esthetic, and pain concerns to a satisfactory level.
