ABSTRACT

ABSTRACT: Ankylosis of the temporomandibular joint is a disorder resulting from fibrous, osseous, or fibro-osseous adhesion that directly affects the quality of life of the individual. The authors present a case of unilateral temporomandibular joint ankylosis treated by condilectomy and ipsilateral sliding vertical ramus osteotomy associated with contralateral sagittal osteotomy aiming to restore function and to correct dentofacial deformity class II. A 31-year-old female patient presented with a history of facial trauma and major complaint of oral opening limitation. Physical examination revealed hypoplasia of the lower third of the face, facial pattern type II, anterior open bite, and maximum mouth opening of 22.5 mm. Computed tomography showed an ankylotic mass in the right mandibular condyle with deformity of the condylar structure and fusion to the right zygomatic arch and a contralateral condylar fracture sequel. It was proposed to perform a condilectomy of the right mandibular condyle for the removal of the bone mass concomitant to the sliding vertical ramus osteotomy of the mandibular ramus for condylar reconstruction by rhytidectomy approach and the sagittal osteotomy of the left mandibular aiming the reestablishment of occlusion and the correction of dentofacial deformity. The condylar fracture was not operated because the condyle was remodeled. The patient is in her fourth year postoperative presenting satisfactory esthetic-functional re-stabilization, without clinical signs of recurrence. In conclusion, the authors believe that combined sliding vertical ramus osteotomy and sagittal osteotomy can bring satisfactory results in complex cases.
