[Radiology of the temporomandibular joint. Diagnostic imaging of the temporomandibular joint].

Diagnostic imaging plays an important role in the diagnosis of disorders of the masticatory system. The most frequent disorders are osteoarthrosis and internal derangements. The clinical diagnosis of these disorders may be confirmed by diagnostic imaging. In addition, diagnostic imaging contributes to the staging of the degenerative changes. Techniques for examination of the temporomandibular joint, including conventional (panoramic, transpharyngeal, transcranial) as well as more sophisticated techniques (tomography, fluoroscopy, arthrography, computed tomography, scintigraphy and magnetic resonance imaging) are briefly described. The interpretation of the radiological image of the joint in health and when affected by osteoarthrosis and internal derangement is presented.

Magnetic resonance evidence of joint fluid with temporomandibular joint disorders.

OBJECTIVES: The relationship between temporomandibular joint (TMJ) effusion and TMJ disorders is controversial. The frequency of TMJ effusion has varied as shown in previous studies. Furthermore, though some authors have suggested a correlation between TMJ effusion and pain, others question the relationship. In order to clarify the relationship, it is necessary to quantify the degree of effusion and thoroughly investigate its relationship to other factors. The purpose of this study was to analyze the amount of TMJ fluid present in joints with TMJ disorders and to see how TMJ effusion is related to TMJ status and pain. METHODS: We studied 577 joints in 293 patients referred to us for magnetic resonance imaging. The joints were divided into painful and nonpainful categories and also classified according to Westesson's criteria for the status of the TMJ. The grading system of Larheim et al was used for categorizing the amount of fluid. Statistical methods were used for analyzing the relationship between TMJ fluid and TMJ status and pain. RESULTS: TMJs with disk displacement without reduction showed the largest amount of fluid while TMJs with normal superior disk position showed the least fluid (Kruskal-Wallis test, P<0.001; Scheffe test, P<0.001). There was a significant difference in the amount of the fluid between painful and nonpainful joints in the group of disk displacement without reduction (Wilcoxon rank sum test, P<0.001). No significant differences were found between other groups. CONCLUSIONS: Joint effusion is likely to appear in painful TMJs with disk displacement without reduction. Joint effusion may be an abnormal entity just suited to joints with disk displacement without reduction.

Relationship between radiographic signs in the temporomandibular joint and hand joints.

The temporomandibular joints of 64 patients and the hand joints of 62 patients with mandibular pain and/or dysfunction were exposed in oblique lateral transcranial, transmaxillary, and dorso-volar projections. The relationship between radiographic signs generally ascribed to osteoarthrosis was investigated. Indices were constructed to quantify the radiographic findings in the two joints. In the temporomandibular joint statistically significant age-independent correlations were found between flattening of the lateral part of the condyle, subcortical sclerosis of the condyle and reduced joint space. In the hand joints statistically significant age-independent correlations were found between osteophytes, subcortical sclerosis, eroded/absent cortical outlining, reduced/obliterated joint space and dislocations. No statistically significant correlation could be found between radiographic findings in the temporomandibular and hand joints. It is concluded that the radiographic signs in the temporomandibular joint of reduced joint space, subcortical sclerosis of the condyle and flattening of the lateral part of the condyle are interrelated and probably characteristic of osteoarthrosis, and that these relationships are similar to those that occur in the hand joints.

Comparative histological contributions to the development of the ear-ossicular joints and the temporomandibular joint in the mouse.

The genesis, differentiation, development and growth of the ear-ossicular joints and temporomandibular joint (TMJ) in the Slc-ICR mouse were studied by means of light and transmission electron microscopy. The differentiation of the ossicular joints and TMJ anlagen was initiated during the fetal stages. Although morphogenesis, development and growth of the TMJ were already evident in the prenatal stages, the joint-cleaving associated with the occurrence of interzones in the cartilaginous ossicular chain was observed during the neonatal stages. However, the simple diarthrodial ossicular joints were completed and became mature earlier than the double synovial TMJ having an articular disc in early postnatal life. TEM examinations revealed that the articulating epiphyseal cartilage of the ossicular joints consisted of hyaline cartilage, while the intracapsular structures in the TMJ were composed of fibrocartilage. The synovium of the diarthroidal joints was supplied by blood vessels, nerve fibers, collagen and elastic fibers. No distinct aging in the cellular and fibrous components of the synovial tissue of the completed TMJ and ossicular joints was evident in the present study.

[Temporomandibular joint disorders and surgery of the temporomandibular joint].

Surgery of the TMJ is a useful tool in Temporo Mandibular Disorders (TMD). After have been identified what is part of TMD and what isn't, this article lay stress upon the fact that surgery of the TMJ is the appropriate treatment only when the nonsurgically therapy had failed. Indications, danger and complications are discussed. Procedures of arthrotomy and arthroscopy are explained. Various surgical procedures and staging of TMD are discussed.

Temporomandibular joint disorder.

Temporomandibular joint disorder is a common clinical entity with diverse etiologies and symptoms. The hallmarks on physical examination are reduced or dysfunctional mandibular range of motion, malocclusion, and joint or preauricular tenderness. The diagnosis is made when a history of craniofacial symptoms or headache is linked with temporomandibular joint dysfunction. Temporomandibular joint disorders usually respond to medical treatment with anti-inflammatory medications, soft diet and occlusal therapy, without the need for surgical intervention. These disorders must be considered in the differential diagnosis of chronic headache, facial pain and compromised mandibular movement.

Inflammatory change in the upper joint space in temporomandibular joint with internal derangement on gadolinium-enhanced MR imaging.

The object of this study was to clarify the relationship between gadopentetate dimeglumine (Gd-DTPA) contrast enhancement of the upper joint space and the severity of internal derangement of the temporomandibular joint (TMJ). Fifty patients with 63 painful TMJs underwent 1.5T MR imaging with T1-weighted images before and after an intravenous injection of Gd-DTPA with or without fat suppression. The relationship was investigated between the contrast enhancement at the upper joint space and disc position, disc morphology or bone morphology. Of the 63 joints, a significant contrast enhancement in the upper joint space was detected in 32 joints. There was a significant high incidence of anterior disc displacement without reduction in the contrast-enhancement positive group compared to the negative group (P = 0.021), but there was no significant difference for disc morphology (P = 0.094) and bone morphology (P = 0.384). Gd-DTPA enhanced MR imaging may potentially have diagnostic value for internal derangements of TMJs.

General joint hypermobility and temporomandibular joint derangement in adolescents.

Joint mobility was assessed in each member of an epidemiological sample of 96 girls and 97 boys, 17 years old, and graded by means of the hypermobility score of Beighton et al. Twenty two per cent of the girls and 3% of the boys could perform five or more of the nine manoeuvres. The prevalence of symptoms and signs of internal derangement in the temporomandibular joint was higher in adolescents with hypermobility of joints (score greater than or equal to 5/9). In subjects with a high mobility score oral parafunctions (overuse) correlated more strongly with several signs and symptoms of craniomandibular disorder than in those with a low score.

[The effect of prognathism surgery on the temporomandibular joint. (A clinical and radiological evaluation of temporomandibular joint changes after various methods of surgery for prognathism)].

On the basis of clinical and roentgenologic examinations of progenia patients which were planned according to our occlusal concept and monitored postoperatively, we established that the condylar displacement in the roentgenogram offers an exact parameter for the extent of operative displacement of the condyles. Nevertheless, a direct conclusion concerning the clinical symptoms or freedom of complaints cannot be established on the basis of this roentgenographic analysis. The roentgenogram also showed considerable condylar alterations in patients with temporomandibular joint symptoms; greater displacement of the condyles was frequently demonstrable with temporomandibular joint complaints.

[Calcium pyrophosphate arthropathy (pseudogout) of the temporomandibular joint].

The temporomandibular joint is rarely affected by crystal deposition disease (gout and pseudogout). Only the temporomandibular joint was affected in a 69-year-old patient with calcium pyrophosphate dihydrate deposition disease (pseudogout). This case is described here. Clinically presenting as painless swelling, computed tomography and magnetic resonance imaging showed signs of a chronic destructive arthritis. The evidence for calcium pyrophosphate dihydrate crystals was provided by histological examination. Diagnostic criteria, differential diagnosis and possibilities for treatment are discussed on the basis of our own experience and the literature.

A radiologic and anatomic study of internal derangements of the temporomandibular joint.

Fifteen temporomandibular joints (TMJs) in unfixed cadavers were examined clinically and then arthrograms were made. Eleven of the TMJ disks were mechanically displaced anteriorly before the arthrograms were made. The joints were removed, fixed, frozen, and sectioned perpendicular to the long axis of the condyle in 2 mm slices. The arthrograms of the joint were compared with arthrograms of each individual section and the original tissue slices to determine whether there was a definite correlation with true anatomic relationships. Because of the complexity of the internal morphology of the hard and soft tissues in the TMJ, no accurate or consistent conclusions about the actual physical relationships could be made by means of arthrogram.

Arthrography of the temporomandibular joint.

The temporomandibular joint is anatomically and functionally complex. Some of its internal secrets may be delineated by careful arthrography. However, the arthrographer must pay as much attention to the dynamic joint as to static images. At the very least, TMJ arthrography has shown that there are anatomic abnormalities which account for many components of the syndrome of TMJ pain and dysfunction. Clicks, locks, perforations, and detachments, as well as their many variations, can be easily documented. As a diagnostic tool, TMJ arthrography is still in its infancy, but it should help in planning rational conservative and surgical intervention. The future for this technique is exciting.

The association between generalized joint hypermobility and temporomandibular joint disorders: a systematic review.

To analyze conflicting evidence in the literature for the association between temporomandibular joint disorders (TMD) and generalized joint hypermobility (GJH), we performed a bibliographic search. The methodological quality of the 14 papers found was assessed according to 14 criteria. Papers were included in the analysis if the study population was clinically relevant, if range of motion of 2 or more joints was assessed on the left and right sides, and if cases had a TMD. Four studies fulfilled these selection criteria. Data from 3 studies, 113, cases and 95 controls, were available for analysis. Twenty-six cases and five controls were hypermobile (odds ratio, 5.4). In a sensitivity analysis, the odds ratio changed from significant to non-significant in 2 of 5 scenarios. As a result, it is not clear whether GJH is associated with TMD, and more rigorous studies are needed.
