“…The costochondral grafts after condylectomy and in reconstruction for unilateral ankylosis were studied in this animal model by MATSUURA et al 9,10 , who found that these grafts fused to the ramus and reconstituted a nearly normal, fully functional joint. TAKAISHI et al 16 have recently tested the functional and histologic fate of an auricular cartilage graft with gap arthroplasty in the reconstruction of an ankylosed TMJ and concluded that it may be useful in preventing reankylosis.…”

“…[20–22] They have stated that this manoeuvre goes a long way in preventing reankylosis and have demonstrated consistent long-term results. In fact, Takaishi et al [23] have conducted a study using nonvascularised auricular cartilage in sheep. Histological examination of the cartilage after three months revealed a viable cartilage with adequate joint space between the cartilage and the glenoid.…”

Context:Surgery for the release of temporomandibular joint (TMJ) ankylosis is a commonly performed procedure. Various interposition materials have been tried with varying success rates. However, none of these procedures attempt to recreate the architecture of the joint as the glenoid surface is usually left raw.Aims:We aimed to use a vascularised cartilage flap and to line the raw surface of the bone to recreate the articular surface of the joint.Settings and Design:There is a rich blood supply in the region of the helical root, based on branches from the Superficial Temporal Artery (STA), which enables the harvest of vascularised cartilage from the helical root for use in the temporomandibular joint.Materials and Methods:Two cases, one adult and the other a child, of unilateral ankylosis were operated upon using this additional technique. The adult patient had a bony segment excised along with a vascularised cartilage flap for lining the glenoid. The child was managed with an interposition graft of costochondral cartilage following the release of the ankylosis, in addition to the vascularised cartilage flap for lining the glenoid.Results:The postoperative mouth opening was good in both the cases with significant reduction in pain. However, the long-term results of this procedure are yet to be ascertained.Conclusions:The vascularised cartilage flap as an additional interposition material in temporomandibular joint surgery enables early and painless mouth-opening with good short-term results. The potential applicability of this flap in various pathologies of the temporomandibular joint is enormous.

“…In an experimental study of the functional and anatomic changes after gap arthroplasty using an animal model, it was reported gap arthroplasty for TMJ ankylosis did not restore the TMJ functionally and histologically to the preexisting state (Matsuura et al, 2001). In human medicine, a variety of interposition materials have been used to prevent recurrence after the treatment of TMJ ankylosis, including skin, temporalis muscle, costochondral, auricular cartilage, non-biological material (Chossegros et al, 1999;Erol et al, 2006;Matsuura et al, 2006;Takaishi et al, 2007).…”

ABSTRACT:An approximately 7-year-old 1.7kg, female Siamese cat with a history of a malocclusion and an inability to open its mouth was referred the Animal Medical Center, Chonbuk National University. The cat had shown signs since it was adopted four years earlier but the cause was not determined. The mandible was deviated 2 mm to left, the mouth could be opened only 2 mm and attempts to open the jaws caused considerable pain. Radiographs indicated new bone formation and a loss of joint space in the right temporomandibular joint(TMJ). 3-dimensional CT showed bony fusion and bone thickness in the right TMJ. The physical, 3-dimensional CT and radiographic examinations revealed right TMJ ankylosis. Under general anesthesia, surgical treatment was performed to remove the ankylosis block with subsequent interpositional arthroplasty using a temporalis myofascial flap. The patient showed distinct improvement in both the articular functionality and clinical signs.
