o e j c m hy consider performing temporomandibular joint TMJ) and orthognathic surgery at the same time hen a patient has coexisting TMJ pathology and a entofacial deformity? Isn’t that too aggressive? How ould the condylar position be controlled? Wouldn’t rthognathic surgery alone correct the TMJ probems? These are certainly suitable questions, but the uthor believes that appropriately trained...

Temporomandibular Joint (TMJ) ankylosis is the pathological osseous or fibrous fusion of the condyle of the mandible with the mandibular fossa of temporal bone. The etiology of TMJ ankylosis includes previous trauma, infection, arthritis and previous TMJ surgery. The Temporomandibular Joint (TMJ) ankylosis in children is rare and the exact causes remain unclear. Trauma is well known as the most...

Bony fusion between the mandibular condyle and skull base involves temporomandibular joint (TMJ) bony ankylosis. This condition might originate from trauma, infection, or systemic disease. TMJ adhesion can develop after synovial damage. Both TMJ ankylosis and adhesion lead to functional impairment and pain. Here, we present a case of a 50-year-old female who had bony ankylosis of the right TMJ ...

Tenascin-C (TNC) is a large hexameric extracellular matrix glycoprotein that is expressed in developing organs and tumors. It has been reported that TNC is expressed in inflamed synovial membranes and deformed discs of temporomandibular joint (TMJ) disorder. However, the role of TNC in TMJ is not fully known. In this study, the role of TNC in fibrous adhesion formation of TMJ was examined using...

Purpose: To investigate the relation between temporomandibular joint (TMJ), pain and anterior open bite versus TMJ structional changes Materials and Methods: Sixty-four patients, 18 men and 46 female, with TMJ involvement of rheumatoid arthritis (RA) were included. 20 healthy patients were included as controls. A clinical examination performed regarding TMJ pain, tenderness to palpation and the...

OBJECTIVE To determine the prevalence and features of temporomandibular joint (TMJ) arthritis by magnetic resonance imaging (MRI) among children with juvenile idiopathic arthritis (JIA), and to identify risk factors for TMJ arthritis. METHODS A retrospective chart review was performed on 187 patients with JIA who underwent a TMJ MRI at Children's Hospital of Alabama between September 2007 and...

Recent recognition of the markedly high prevalence of temporomandibular joint (TMJ) arthritis in children with juvenile idiopathic arthritis (JIA) coupled with the significant morbidity associated with TMJ damage has prompted increased interest in both the clinical and pathological aspects of TMJ arthritis. This review focuses on the prevalence of TMJ arthritis in JIA, the imaging modalities us...

Trauma is the predominant causal factor for temporomandibular joint (TMJ) ankylosis. However, the relationship between condylar fracture and TMJ ankylosis is complicated. It is believed that post-traumatic TMJ ankylosis arises from TMJ intracapsular changes, including damaged cartilage, displaced or disrupted discs, haematoma formation and subsequent fibrosis and calcification in the joint. In ...

The present study was designed to test the hypothesis that estrogen exacerbates inflammation of the temporomandibular joint (TMJ). Evans blue dye was used to quantify plasma extravasation (PE) around the rat TMJ. In an initial set of experiments, TMJ PE was compared in naïve intact male and female rats, as well as in both groups after complete Freund's adjuvant (CFA)-induced inflammation of the...

Tissue-engineering of the temporomandibular joint (TMJ) disc aims to provide patients with TMJ disorders an option to replace diseased tissue with autologous, functional tissue. This study examined clinically relevant cell sources by comparing costal chondrocytes, dermal fibroblasts, a mixture of the two, and TMJ disc cells in a scaffoldless tissue-engineering approach. It was hypothesized that...
