Temporomandibular disorders encompass multiple pathologies of the temporomandibular joint that manifest as middle/inner ear symptoms, headache, and/or localized TMJ symptoms. There is an important although somewhat limited role of imaging in the diagnostic evaluation of temporomandibular disorders. In this manuscript, we provide a comprehensive review of TMJ anatomy, outline potentially important features of TMJ disc ultrastructure and biochemistry in comparison with the intervertebral disc and knee meniscus, and provide imaging examples of the TMJ abnormalities currently evaluable with MRI and CT.

[MRI and arthrography in the evaluation of TMJ disorders].

Nihon Igaku Hoshasen Gakkai Zasshi 1991 Aug;51(8):912-22

Center for Radiological Science, Iwate Medical University.

Arthrosis of the temporomandibular joint (TMJ) is a noninfectious, noninflammatory condition characterized by joint pain, noise (clicking) and abnormal motion. It contains various disease processes, such as abnormalities in the menisci or masticating muscles, subluxation of the condyle and degenerative joint disease. Analysis of the morphology and dynamics of TMJ by means of imaging modalities has become highly advanced since the development of arthrography in the late 1970s. Read More

R E Greenwood

Br J Oral Maxillofac Surg 1989 Apr;27(2):156-62

King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia.

A retrospective study of 106 patients who underwent temporomandibular joint surgery for meniscal dysfunction was conducted. The patients were evaluated by tomography and arthrography of the temporomandibular joint and abnormalities of the hard and soft tissue structures were determined by these investigations and compared directly with the findings at surgical examination. Tomography had a high degree of correlation with bony pathology as did arthrography with meniscal displacement. Read More

Correlation of magnetic resonance imaging and surgical findings in patients with meniscal perforation.

J Craniomandib Disord 1989 ;3(3):174-8

Advancement of surgical techniques has made it necessary to accurately diagnose internal derangements. Arthrography and computerized tomography have been used to diagnose the majority of temporomandibular joint disorders; however, these methods have had their disadvantages. Magnetic resonance imaging utilizing surface coils has greatly improved the ability to diagnose meniscus abnormalities without using interarticular injections or ionizing radiation. Read More

[Nuclear magnetic resonance tomography of the temporomandibular joint. Comparison with computerized tomography and arthrography].

Rofo 1986 Jul;145(1):38-43

79 patients aged 6 to 66 years (9 men and 70 women) with abnormalities of the TMJs were examined by magnetic resonance tomography (132 joints) and the results were compared with CT (16 joints) and arthrography (39 joints). Magnetic resonance tomography showed forward luxation of the meniscus in 82 joints (62%). In 34 joints (26%) the meniscus spontaneously resumed normal position when the mouth was open, but in 48 joints (36%) the displacement was permanent. Read More

Overview of computed tomography of the temporomandibular joint.

J Comput Tomogr 1985 Oct;9(4):351-8

Computed tomography of the temporomandibular joint has been shown to be an accurate method of assessing the position of the disk. To date, we have examined over 500 patients with this modality and have found it also to be effective in the evaluation of other osseous and soft tissue abnormalities. An overview of temporomandibular joint pathology is presented, including the range of osteoarthritic changes from spur formation to complete fusion. Read More

Mandibular range of motion versus arthrographic diagnosis of the temporomandibular joint.

Oral Surg Oral Med Oral Pathol 1985 Sep;60(3):244-51

The range of mandibular movements has been correlated with arthrographic findings of the temporomandibular joint in 205 patients. Abnormalities of meniscus position and function have been found to influence mandibular movements in characteristic patterns. However, altered mandibular movements alone are insufficient for a definitive clinical diagnosis of the specific type of internal derangement of the temporomandibular joint. Read More

The temporomandibular joint: true sagittal computed tomography with meniscus visualization.

Radiology 1984 Jan;150(1):250-4

Accessory patient support equipment was constructed that allows patient positioning for true sagittal projection of the temporomandibular joint using a GE 8800 CT/T scanner. Range of motion abnormalities, osseous alterations of the mandibular condyle and temporal bone, joint-space narrowing, and meniscal configuration may be demonstrated. The technique has potential advantages over other CT projections and sagittal reconstruction for evaluation of temporomandibular joint dysfunction. Read More

Internal derangements of the temporomandibular joint: an assessment of condylar position in centric occlusion.

J Prosthet Dent 1983 Feb;49(2):250-4

Subjects experiencing painful dysfunction of the TMJ and diagnosed by arthrography to have displacements of the meniscus were compared to normal or asymptomatic subjects to assess condyle-fossa relationships. The groups did not differ by linear or area determinations of the P/A ratio. The use of plain film alone is not adequate for diagnosis or assessment of treatment if abnormalities of meniscus function are the primary etiology. Read More
