A new method of condylar reconstruction after gap-arthroplasty in extensive ankylosis of the temporomandibular joint in adults is presented. An autogenous graft, consisting of the excised ankylotic mass, was contoured, reimplanted and used for condylar reconstruction. This technique has given good results and is a simple alternative to other methods of reconstruction in adults. Successful results in three cases with more than 12 months' follow up, has prompted us to use this technique routinely in adult patients.
