  • The aim of this study was to present a case series of the orthognathic treatment of facial asymmetry due to temporomandibular joint (TMJ) ankylosis and to characterize the current treatment modalities through a literature review. Four patients who presented with facial asymmetry due to TMJ ankylosis between 2010 and 2014 were included in this study. TMJ ankylosis was surgically treated before bimaxillary surgery with advancement genioplasty in some of the cases. In 2 cases, 3-dimensional (3D) models were used for diagnosis and treatment planning, as 3D models are very important tools for planning surgical maneuvers. Aesthetically pleasant facial symmetry and a good facial profile were obtained in all the cases.

  • Bony ankylosis is an intraarticular condition where there is fusion of the bony surfaces of the joint : The condyle and the glenoid fossa. It occurs in both children and adults, unfortunately more frequently in the former, in whom early recognition and correction is particularly critical. Trauma is well proven to be the predominant cause of TMJ ankylosis. Infection, rheumatoid arthritis and neoplasm are another, significant cases of TMJ ankylosis. The necessity for using an interpositional material to prevent TMJ reankylosis has been widely discussed and many interpositional materials have been used, including temporal muscle and fascia, dermis, auricular cartilage, fascia lata, fat, Lyo-dura, Silastic and various metals. The temporal muscle and fascia have been widely used pedicled flap for head and neck reconstruction. The use of a temporal muscle and fascia for reconstruction of the TMJ, particularly in cases of ankylosis is a very reasonable option. Its principle advantages are its autogenous nature, resilience, and proximity to the joint, allowing for a pedicled transfer of vascularized tissue into the joint area. However, the viability of temporal muscle and fascia is a critical question. We treated 2 cases of TMJ ankylosis with temporal muscle and fascia transfer and one case with temporal fascia. We obtained satisfactory results as to functional aspects.

  • Background: Temporomandibular joint (TMJ) ankylosis can be accompanied by various degrees of functional and esthetic problems. Adequate mouth opening, occlusal stability, and harmonious facial form are the main goals of treatment for ankylosis. Distraction osteogenesis has proven to be an excellent treatment for lengthening the ramus-condyle unit. However, various timings for distraction have been suggested, and there is no consensus on selection criteria for performing the procedure in stages or simultaneously with other treatments. Case presentation: In this case report, concomitant intraoral distraction and gap arthroplasty was planned to treat TMJ ankylosis and associated facial asymmetry. After gap arthroplasty and 23 mm of distraction, the ramus-condyle segment was successfully lengthened and mouth opening range was significantly increased. The resultant interocclusal space was stably maintained with an occlusal splint for 4 months after distraction. Finally, good occlusion was achieved after prosthetic treatment. The remaining mandibular asymmetry was corrected with osseous contouring and augmentation surgery. The mouth-opening range was maintained at 35 mm 24 months after treatment. Conclusion: Gap arthroplasty with intraoral distraction as a one-stage treatment and subsequent contouring surgery can be applied to correct ankylosis with moderate malocclusion and facial asymmetry.

  • Objectives: The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. Materials and Methods: Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (${\geq}35mm$) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. Results: With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. Conclusion: Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

  • The authors have observed and treated the two patients with true bony ankylosis of temporomandibular joint in 16 years old school boy and 24 years old korean male. The ankylosed patients were treated by condylectomy and arthroplasty such as resin condylar head graft having been made into acrylic resin. 1. In 16 years old school boy, temporoandibular ankylosis of left side was surgical_y approached by condylectomy including coronoid process and posterior border of ramus and resin condylar head graft by means of interosseous wiring. 2. In 24 years old korean male, bilateral temporomandibular ankylosis was treted by bilateral condylectomies and resin condylar head grafts. 3. The mouth opening has been continued as 3-5cm since 13 months and 8 months before and facial appearances were very excellent.

  • Background This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. Methods A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation. Results A significant increase in interincisal distance of 32 mm was seen in 12 (92.31%) patients in the T-plate interposition group, in 2 (25%) cases of the temporalis muscle flap interposition group, and in 1 case (14.28%) of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69%) of the T-plate interposition group, while as it was observed in 4 (50%) cases in the temporalis muscle flap interposition group and 4 (57.14%) cases in the condylectomy group, and these differences were statistically significant. Conclusions Our clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

  • Management of temporomandibular joint (TMJ) ankylosis is challenging for the oral and maxillofacial surgeon because it involves the mouth opening, dentofacial deformity, diet problem, and quality of life. Although surgical techniques to treat TMJ ankylosis have improved, reankylosis is a persistent problem. The temporalis myofascial flap provides good material for interpositional arthroplasty, because of its good vascular supply, anatomic proximity, and adequate thickness. This case report examines the efficacy of submandibular anchorage to prevent reankylosis by inhibiting flap dislocation.

  • Bilateral true bony ankylosis of temporomandibular joint is extremely rare. Treatment in all cases should be surgical. Considerable difficulty has been encountered by surgeons in the judgment of the planning of the treatment for ankylosis : either by gap arthroplasty treatment because of no recurrence and the excelent results obtained. I performed an osteoarthrotomy and interposition arthroplasty bilaterally, using combined materials consisting of acrylic resin and gold plate. My experience with alloplasty in ankylosed temporomandibular joints is pressented.
