this study was done to evaluate the use of transport distraction osteogenesis in restoring the deficient condyle/ramus unit of patients with unilateral or bilateral TMJ ankylosis to correct the resultant deformity
10 patients with post ankylosis deficient ramus /condyle unit who underwent release procedure in the Maxillofacial and Plastic Surgery Department, Faculty of Dentistry, Alexandria University, Egypt. all patients were assessed clinically and by imaging using OPG, lateral and PA cephalometry, and cone beam CT to assess the deficient ramus/condyle unit (RCU) then patients were operated using transport distraction osteogenesis to lengthen the RCU. Then follow up of all patients both clinically and radiographically was adopted.
