INTRODUCTION: The aim of this study was to report Jordanian experience in surgical treatment of TMJ ankylosis in 22 children. PATIENTS AND METHODS: This retrospective clinical study included children who were diagnosed with TMJ ankylosis and were treated in a dental teaching centre between 1993 and 2001. Patients underwent the release of 24 temporomandibular joint ankyloses and two different surgical techniques were used: either reconstruction of the condyle using costochondral grafts, or using the temporalis muscle as an interpositional material. Patients were followed up for 1-8 years. RESULTS: Twenty-two children (13 males and 9 females) were included in the study. Costochondral grafts were used as a reconstruction material in 16 TMJs (67%), whilst temporalis muscle was used as an interpositional material in 8 joints (33%). The mean preoperative maximum interincisor distance was 6.6 mm+/-1.3, which was increased to a mean of 30.3 mm+/-2.5 postoperatively. Two female patients (9%) suffered recurrence of the ankylosis within 6-12 months postoperatively. In one of these, a costochondral graft was used and temporalis muscle interposition in the other. CONCLUSION: Costochondral graft as a reconstruction material and temporalis muscle as an interpositional material showed comparable success rates when treating TMJ ankylosis in 22 children.
