Temporomandibular joint
The temporomandibular joint (TMJ) is an atypical synovial joint located between the condylar process of the mandible and the mandibular fossa and articular eminence of the temporal bone. It is divided into a superior discotemporal space and inferior discomandibular space by the TMJ disc (or meni...
Article
Temporomandibular joint pathology
Temporomandibular joint (TMJ) pathology encompasses three main entities:
temporomandibular joint dysfunction: relating to abnormal TMJ disc relationship to condyle and temporal bone, which can lead to osteoarthritis.
temporomandibular joint inflammation
temporomandibular joint trauma
See als...
Article
Temporomandibular joint disc
The temporomandibular joint (TMJ) disc (or meniscus) is made of fibrocartilage and divides the temporomandibular joint into two compartments.
Gross anatomy
The disc is composed of fibrocartilage, with crimped collagen, thought to better absorb impact. It has a biconcave shape with a thicker p...
Article
Temporomandibular joint trauma
The temporomandibular joint (TMJ) can be affected by trauma in a number of ways:
condylar process fractures
temporomandibular joint dislocation
fracture of the mandibular fossa
Article
Temporomandibular joint dislocation
Temporomandibular joint dislocation represents the condyle of the mandible being abnormally displaced, with a loss of the normal articulation with the temporal bone's mandibular (glenoid) fossa.
Epidemiology
Dislocations of the temporomandibular joint (TMJ) are common and occur in as many as 7...
Article
Temporomandibular joint inflammation
Temporomandibular joint (TMJ) inflammation may occur as a result of an inflammatory arthropathy or secondary to TMJ dysfunction. Since the TMJ is a synovial joint, it is susceptible to inflammatory arthropathies that affect other joints.
rheumatoid arthritis (RA): is by far the most common

Osteoarthritis of the temporomandibular joint
Osteoarthritis of the temporomandibular joint (TMJ) is the end point of long-standing TMJ dysfunction. It is a common finding incidentally on a base of skull imaging, and it should be remembered that TMJ pain does not correlate well with osteoarthritic changes. Indeed pain from TMJ dysfunction i...
Article
Temporomandibular joint dysfunction
Temporomandibular joint (TMJ) dysfunction is characterized by an abnormal relationship between the disc and the adjacent articular surfaces (condyle below with mandibular fossa and articular eminence above).
Epidemiology
TMJ dysfunction is far more common in women (F:M 8:1).
Clinical present...
Article
Temporomandibular joint effusion
Temporomandibular joint (TMJ) effusions are unusual in asymptomatic patients, and thus should trigger a careful search for underlying pathology. It usually precedes osteoarthritis of the TMJ. Effusions are seen in:
TMJ dysfunction
septic arthritis
rheumatoid arthritis (RA)
Radiographic featu...
Article
Stuck temporomandibular joint disc
A stuck disc, also called anchored disc phenomenon, refers to a temporomandibular joint (TMJ) disc which does not translate anteriorly out of the mandibular fossa onto the articular eminence but rather remains (thus "stuck") in the fossa. It is a form of TMJ dysfunction.
Clinical presentation

Article
Temporomandibular joint (axiolateral oblique view)
The axiolateral oblique temporomandibular joint (TMJ) view allows for visualization of the articular tubercle, mandibular condyle and fossa of the temporomandibular joint (TMJ).
Indications
This projection is useful in identifying structural changes and displaced fractures, assessing excursion...
