“…In human patients, fracture of the condylar process of the mandible can cause a displacement of the articular disk, which removes the physical impediment to transarticular bony fusion and may result in TMJ ankylosis. 40–42 Also, the position of the articular disk in the TMJ was significantly associated with the position of the fractured bone fragments. 40 However, despite the association of articular disk displacement with fractures of the TMJ, post-traumatic TMJ ankylosis is rare in humans patients, with an annual incidence rate of approximately 0.4%.…”

Objective To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Design Retrospective case-series. Animals 41 dogs and 17 cats. Procedures Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Results Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Conclusions and Clinical Relevance Results indicated that TMJ disorders are frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and pain.

“…Laskin [6] generalized the factors related to disease, including the age of the patient, severity of trauma, pattern of condylar fracture, duration of immobilization, and location of the disc. Patients characterized with young [6,26], severe TMJ trauma [6], communited condylar fracture [6,26,27] or sagittal fracture [11,26-28], or those with medially dislocated condylar fracture [14], prolonged immobilization of the mandible [6], and disc displacement [6,28] are prone to developing ankylosis. In addition, close contact of the 2 injured articular surfaces, which results in a shorter distance for bone healing, also plays an important role in the development of ankylosis [11].…”

Current concepts in the pathogenesis of traumatic temporomandibular joint ankylosis

Traumatic temporomandibular joint (TMJ) ankylosis can be classified into fibrous, fibro-osseous and bony ankylosis. It is still a huge challenge for oral and maxillofacial surgeons due to the technical difficulty and high incidence of recurrence. The poor outcome of disease may be partially attributed to the limited understanding of its pathogenesis. The purpose of this article was to comprehensively review the literature and summarise results from both human and animal studies related to the genesis of TMJ ankylosis.

“…Function of the disc plays a keyrole in TMJ unrestricted movement (2,4,5,12,16). In CHF, despite of the fact that the disc is usually stretched and displaced anteromedially there were no ruptures or another pathological changes seen in our series of cases.…”

“…These anatomical changes coupled with pain may decrease mandibular movement and interrupt the mechanical barrier the disc provides and can provide the enviroment for future ankylosis. To avoid these pathological posttraumatic changes and avoid heterotopic bone formation is the goal of the precise anatomical repositioning of medial pole of the condyle together with re-establishment of its relationship to the articular disc (1,2,7,10). From the ethical reasons it is not possible to make a randomized study in this controversial topic.…”

Management of condylar head fractures (CHF) of the temporomandibular joint (TMJ) remains a source of controversy. Based on established literature, group of CHFs and conservative treatment connected with period of maxillomandibular fi xation (MMF) increases the risk for TMJ ankylosis. This paper presents anatomical and functional results of surgical treatment of condylar head fractures in a group of 24 patients (29 joints). Fractures were diagnosed based on conventional radiographs and computed tomography (CT) scans. Utilising an intraoperative arthroscopy authors evaluated actual intraarticular posttraumatic changes. This study presents acceptable functional and radiological results of surgical treatment of condylar head fractures with more than 3-year follow-up. The authors believe that re-establishing the pretraumatic anatomic position of the TMJ components (fragment and the disc) and early postoperative rehabilitation are inevitable to minimize the risk of postraumatic TMJ ankylosis (Tab. 2, Fig. 8, Ref. 31).
