RESUMEN
The temporomandibular joint (TMJ) ankylosis describes the bone or fibrous adhesion of the TMJ components, with functional impairment. The present report shows the surgical correction the TMJ ankylosis due to a condyle fracture in a child. A 12-year-old patient, female, attended to the Oral and Maxillofacial Surgery Department of the Clinical Hospital/Federal University of Uberlândia, showing severe mouth opening limitation (9 mm) and history of bilateral condyle fracture and symphysis fracture. The right TMJ ankylosis was diagnosed, removed, reshaped, and repositioned to form the reshaped condyle, by the sliding reconstruction of the condyle using posterior border of mandibular ramus and myofascial interposition of the temporal fascia. Five months of follow-up showed mouth opening of 44 mm maintained after 2 years, without complaints. The surgical treatment of the TMJ ankylosis is needed for the reestablishment of the immediate function; however, the patient must be watched until the end of development.
