Nov 11, 2024 · 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 meniscus).

Dec 17, 2012 · The document discusses imaging modalities for evaluating the temporomandibular joint (TMJ). Plain radiography and computed tomography are used to image bony structures of the TMJ, while arthrography, MRI and ultrasound can evaluate soft tissues like the articular disc.

Apr 4, 2023 · The axiolateral oblique temporomandibular joint (TMJ) view allows for visualization of the articular tubercle, mandibular condyle and fossa of the temporomandibular joint (TMJ).

Computed tomography and ultrasound imaging have specific indication in imaging of the TMJ. This article focuses on state of the art imaging of the temporomandibular joint. Relevant normal anatomy and biomechanics of movement of the TMJ are discussed for better understanding of many TMJ pathologies.

Normal appearances of the temporomandibular joint. It is typically imaged in the open and closed positions.

TMJ radiographic examinations include transcranial (oblique lateral view), trans maxillary (modified AP view), trans pharyngeal (oblique lateral view), and submental vertex radiographs. Cross-sectional imaging is usually indicated in cases where malocclusion or intra-articular abnormalities are suspected.

Oct 23, 2014 · Knowledge of the normal imaging appearance of the TMJ, its appearance on radiological examination, and interventional techniques are useful for providing a meaningful radiologic contribution.

Conventional radiography, nowadays, is of limited interest. The use of flat plane films for TMJ pathology is not sufficient, because this joint requires three dimensional imaging views. Osseous changes are better visualized with CT and cone beam CT.

Sep 18, 2017 · MR imaging allows detailed evaluation of temporomandibular (TMJ) anatomy because of its inherent tissue contrast and high resolution. Joint biomechanics can be assessed through imaging patients in the closed and open jaw positions.

Sep 26, 2024 · A comprehensive understanding of the normal imaging appearance of the temporomandibular joint as well as the wide range of potential pathologic conditions is essential for conducting an accurate radiologic assessment.
