ABSTRACT:Temporomandibular joint (TMJ) ankylosis is a distressing state where there is inadequate mandibular movement that may be related with grave functional and aesthetic deformities together with trismus, temporomandibular joint (TMJ) ankylosis can be classified into fibrous and bony replacement of the articulating surfaces, consequentially fetching trouble in opening the mouth. One important and most followed treatment is the joint interpositional arthroplasty which aims at removal of the ankylosed tissue and meniscus. Once done, the joint surfaces are smoothened, and the meniscus is replaced by an autogenous or alloplastic material. Different autogenous materials used are costochondral grafts, metatarsal grafts, sternoclavicular grafts, and grafts from iliac crest, fibular grafts, coronoid grafts and parts of ramus. Of these, CCGs are found to be the most commonly followed efficient modality of treatment. The use of abdominal dermis fat grafts has also been reported over eons. This review compares the use of CCGs and abdominal grafts as interpositional materials in interpositional arthroplasty.
