Treatment guidelines for temporomandibular joint ankylosis with secondary dentofacial deformities in adults

Retrospective comparison of autogenous cosotochondral graft and coronoid process graft in the management of unilateral ankylosis of the temporomandibular joint in adults

“…[2][3][4][5][6][7][8] The mandibular coronoid process has been widely used as a bone graft in craniomaxillofacial surgery for some time. [9][10][11] In our previous experimental and clinical studies [12][13][14][15][16][17] we confirmed the ability of the autogenous coronoid process to restore the mandibular condyle satisfactorily. However, we know of few reports that have compared the use of costochondral and coronoid process grafts for condylar reconstruction, 18 despite them both having been reported to give satisfactory results for condylar reconstruction.…”

Management of temporomandibular joint ankylosis in Yemeni children by metatarsal bone grafts.

“…Treatment of true ankylosis of the TMJ is surgical. One of the surgical methods is condylectomy, but it has lost its popularity as it is technically difficult to release the fused remnants of the condylar head exactly at the joint space 23 and that re-ankylosis is not rare.…”

“…23,25 At the beginning, stainless steel, chrome-cobalt, etc., were used for interposition, but later silicone blocks and porous proplast-teflon were popularized. 25 Alloplastic materials preserve the vertical height of the ramus.…”

“…25 Allergic reactions, foreign body reactions, and erosion of the glenoid fossa are the other complications. 23,25 It is also an expensive method and must not be used in growing patients. 25 The use of biological materials such as fascia lata and muscle or dermal fat graft may not preserve the vertical height of the mandibular ramus, therefore retrognathia, apertognathia, laterognathism, and open-bite deformity may develop.…”

“…25 The use of biological materials such as fascia lata and muscle or dermal fat graft may not preserve the vertical height of the mandibular ramus, therefore retrognathia, apertognathia, laterognathism, and open-bite deformity may develop. 23 Many reports have documented the rationale for the use of costochondral graft in reconstruction of the TMJ; however, pneumothorax and perichondritis may occurr. 13,26 In the present study, the metatarsal bone graft was used because of its biological compatibility, workability, functional adaptability, and minimal additional detriment to the patient.…”
