Simultaneous arthroplasty and distraction osteogenesis for the treatment of ankylosis of the temporomandibular joint and secondary mandibular deformities in children

The purpose of this study was to explore the use of simultaneous arthroplasty and distraction osteogenesis in the treatment of children with ankylosis of the temporomandibular joint (TMJ) and secondary mandibular deformities. Between January 2012 and December 2016, 17 children (7 boys and 10 girls, mean (range) age 7 (4–12) years) were treated. Preoperatively, the mean (range) maximal incisal opening was 1.4 (0–5) mm. Distraction osteogenesis was used to elongate the mandibular body or ramus, or both, after the release of ankylosis.
