The temporomandibular joint (TMJ) is a complicated anatomical structure that is concerned with mastication, deglution, speech and head posture. Ankylosis of the TMJ occurs when the condyle is fused to fossa by bony or fibrous tissue. The purpose of this study is to discuss the correction of facial asymmetry caused by ankylosis of the temporomandibular joint. The correction is a combination of vertical and horizontal mandibular distraction osteogenesis. In the first surgical operation, facial deformities are corrected. The second stage the arthoplasty is performered. This case discusses alterations for ankylosis madibular growth for young people including deformity correction and mouth opening formation. TMJ ankylosis in the pediatric patient often leads to facial deformity, difficulty chewing and swallowing, and poor oral hygiene. This report presents the results of distraction osteogenesis using bidirectional intraoral and extraoral devices in 5 patients with different grades of vertical and horinzontal mandibular ramus hypoplasia.
