We presented clinical cases of successful surgical treatment of patients with recurrent ankyloses of the temporal and mandibular joint (TMJ). The main symptoms of the disease among patients were persistent restriction of mouth opening, difficulty of speech and carrying out regular oral hygiene, food intake. According to the data of computed tomography (3D reconstruction and layer-by-layer sections) bone ankyloses of temporal-lower joints are diagnosed. Patients were successfully operated on with good immediate and distant treatment outcomes.

A clinical case of successful medical rehabilitation of a patient with monostotic fibrous osteodisplasy of mandible is presented. After resection of the branch and body of the left mandible with disarticulation in the temporomandibular joint, the defect was replaced by free revascularized fibula flap. The missing joint process was restored with a titanium condylar endoprosthesis, and fixed to the proximal part of autotransplant using special screws.
