TMJ ankylosis is classified with true and false type. A true ankylosis is defined as any condition that produces fibrous or bony adhesions between the articular surfaces of the temporomandibular joint. The main causes of true ankylosis are trauma or infection. A false ankylosis results from pathologic conditions outside the joint that limit mobility of the mandible such as myogenic disorders, coronoid impingement or rare direct bony fusion between maxilla and mandible. The treatment of choice of TMJ ankylosis is surgical intervention. We experienced the male patient with complete mouth opening limitation since 45 years before. This patient has true TMJ ankylosis and rare bony synostosis between maxilla and mandible in the right posterior region. We performed surgical intervention and had a favorable result.

We conducted a retrospective study and reviewed the temporomandibular joint (TMJ)-related papers published in a leading international journal, Journal of Oral and Maxillofacial Surgery, between January 2014 and December 2015. The study was conducted to ascertain and compare the trends of articles being published in the years 2014 and 2015. A total of 28 articles were reviewed, of which most of the full-length articles were on clinical management and outcomes and the role of radiology. The bulk of the studies were prospective, and less interest was shown in experimental research. A thorough review and analysis thus gives the impression that there is a great need for well-designed clinical studies on TMJ.

Temporomandibular joint (TMJ) prosthesis have been hesitated to use because of bitter memories about Proplast-Teflon interpositional TMJ implants. Many clinicians, however, are trying to use total TMJ prosthesis with getting continuous long-term follow-up results. Alloplastic total TMJ replacement have been applied to much more patients who have failed previous TMJ prostheses or TMJ implants, fibrous/bony ankylosis, severe osteoarthritis, degenerative joint disease, idiopathic condylar resorption, condyle loss by trauma or tumor resection, and other bony destructive diseases. Nowadays three types of total TMJ prosthesis are widely used. In this article, indications, types of prosthesis, safety and stability would be demonstrated with a case report.

Background: The purpose of this study is to evaluate the outcomes of four patients receiving stock Biomet TMJ prosthesis for reconstruction of the TMJs. Methods: TMJ reconstruction with stock Biomet TMJ prosthesis was performed in four patients who had joint damages by trauma, tumor, resorption, and ankylosis, which represent the indications of alloplastic prosthesis. Results: Loss of condyle from trauma and resorption of joint are good indications for prosthesis, but the patients should be informed about limitation of jaw movement. In case of structural damage of TMJ by tumor, tumor recurrence should be considered before planning TMJ reconstruction. Considering heterotopic bone formation in case of ankylosis, periodic follow-up and special surgical technique are required. Conclusions: Given careful treatment planning and understanding the functional limitation of TMJ prosthesis, alloplastic prosthesis is a safe and effective management option for the reconstruction of TMJs.

Temporomandibular ankylosis is defined as a situation in which the condyle is fused to the fossa by bone or fibrous tissue. Conditons such as trauma, infection, or systemic disease may predispose to various types of ankylosis, bringing about different levels of limitation in mandibular movement. Most patients with temporomandibular ankylosis are associated with limitation of maximal mouth opening, deviation of the chin toward the affected side, impaired occlusion, chronic pain, compromised oral hygiene, severe facial asymmetry & impeded mandibular molar eruption occurring in childhood. Several techniques to release ankylosis have been described in the literature, showing variable and often unsatisfactory results. The most frequently used operations are gap arthroplasty, interpositional arthroplasty, and exicision and joint reconstruction with autogenous or alloplastic materials. We have managed the two patients of TMJ ankylosis. They had previously TMJ surgery and we treated with gap arthroplasty & active physial therapy. We have obtained favorable results and report these cases with literatures review.

Destruction of normal temporomandibular joint architechture may produce serious functional and cosmetic deficiencies. The literature is well documented as to the etiology and pathogenesis of temporomandibular joints. Numorous surgical procedure have been advocated for temporomandibular joint ankylosis from condylectomy to arthroplasty, cartilage transplant, metallic prosthesis, interpositional implant. These were to able reconstruct the normal mandibular function, and any even procedure could obtain the satisfactory results. In this paper, we reviewed young adult patient with TMJ ankylosis and facial asymmetry who was treated with metallic condylar prosthesis and orthognathic surgery.

This is a case of bony ankylosis of right temporomandibular joint with mild facial asymmetry resulted from trauma, which bring about the right condylar fracture, and corrected by interpositional arthroplasty with temporal fascia flap and coronoidectomy. The postoperative results were functionally and esthetically good, but continued osbervation is necessary to evaluation of abnormal bony growth and reankylosis.

Subcondylar fractures have generally been treated by intermaxillary fixation except in cases where there is an absolute indication for open reduction. The reason behind a less aggressive surgical approach lies on the inherent difficulties in manipulating fragments in such a small area at the risk of damaging facial nerves or vessels such as the internal maxillary artery. However, long-term follow-up studies showed that conservative treatment of subcondylar fractures results in disturbances of occlusal function, deviation of the mandible, internal derangement of the temporomandibular joint, and ankylosis of the joint. We carried out open reduction of dislocated subcondylar fractures in 14 patients from 2000 to 2004 by a retromandibular approach. After the reduction of fractured bone, two H-shaped miniplates with 6 holes were fixed with screws at the anterior and posterior surfaces of the subcondyle. The retromandibular approach allowed good access and easy manipulation of the subcondyle. Immediate relief from malocclusion and correction of mandibular midline shifting were observed in all patients. Late temporomandibular dysfunction and ankylosis were not observed. Open reduction with plate osteosynthesis made it possible to avoid IMF in 7 of the 14 patients. The present study shows that open reduction through this retromandibular approach can produce good outcome in adult patients with subcondylar fracture.

Most patients with temporomandibular disorder can be treated conservatively. However, open TMJ surgery can be needed in some patients. We analysed the patients with TMD which open surgery has performed since 1998. Open surgery was carried out in 8 patients. Age ranged from 22 to 61 years, with a mean of 42.8years. All patients were male. Final diagnosis was obtained based upon clinical, radiographic and operative finding as follows; habitual luxation, bony ankylosis, traumatic arthritis, disc displacement with destructive change, disc displacement and adhesion. Etiologic factors included trauma(4), infection(2), and unknown(2). Open surgery included arthroplasty with either of condylectomy, eminectomy, meniscoplasty, capsurrohaphy. All patients were recovered uneventfully without severe complications. Some mouth opening limitation and mouth opening deviation remained. Postoperative aggressive physical therapy and careful follow up were performed. In conclusion, open TMJ surgery must be considered in organic disease such as ankylosis, tumor and TMD without favorable recovery after long-term conservative therapy.
