Autogenous ear cartilage interpositional graft following menisectomy in the temporomandibular joint

Disc displacement in temporomandibular joint surgery has been troublesome. Problems-migration, foreign body reation, bony erosion, secondary pain & swelling, fragmention etc.-have occured. The autogenous graft, rather than alloplastic materials, may be the material of choice when replacement of the temporomandibular joint disc is indicated. The technique and results of replacement of the articular disc by autogenous ear cartilage are presented. In the three patients-five joint-operated with a follow up from eleven to twelve months, all patient were improved in postoerative symptoms, mouth opening ranges and jaw functions. The autogenous ear cartilage appeared to be a suitable autogenous tissue graft, maintaining its viability and functioning as an interpositioning material between the condyle and fossa.
