The authors present a review of seven patients (eight joints) with temporomandibular ankylosis treated between 2007 and 2008. The aim of this retrospective study was to present the experience of using full thickness skin-subcutaneous fat grafts, harvested from the patient's abdomen as interpositional material after gap arthroplasty. All patients presented with osseous ankylosis and were graded according to Topazian's classification. Postoperative follow up ranged from 12 to 24 months. Maximal inter-incisal opening (MIO) on presentation ranged from 0 to 8mm, which stabilized to 27-44mm at follow up. There was no evidence of re-ankylosis. This study found merit in the use of autogenous full thickness skin-subcutaneous fat graft as an interpositional material for up to 2 years following ankylosis release.
