Temporomandibular joint (TMJ) abnormalities cannot be reliably assessed by a clinical examination. Magnetic resonance imaging (MRI) may depict joint abnormalities not seen with any other imaging method and thus is the best method to make a diagnostic assessment of the TMJ status. In patients with temporomandibular joint disorder (TMD) referred for diagnostic imaging the predominant TMJ finding is internal derangement related to disc displacement. This finding is significantly more frequent than in asymptomatic volunteers, and occurs in up to 80% of patients consecutively referred for TMJ imaging. Moreover, certain types of disc displacement seem to occur almost exclusively in TMD patients, namely complete disc displacements that do not reduce on mouth opening. Other intra-articular abnormalities may additionally be associated with the disc displacement, predominantly joint effusion (which means more fluid than seen in any asymptomatic volunteer) and mandibular condyle marrow abnormalities (which are not seen in volunteers). These conditions seem to be closely related. Nearly 15% of TMD patients consecutively referred for TMJ MRI will have joint effusion, of whom about 30% will show bone marrow abnormalities. In a surgically selected material of joints with histologically documented bone marrow abnormalities nearly 40% showed joint effusion. Disc displacement is mostly bilateral, but joint effusion seems to be unilateral or with a lesser amount of fluid in the contralateral joint. Abnormal bone marrow is also mostly unilateral. Many patients have unilateral pain or more pain on one side. In a regression analysis the self-reported in-patient TMJ pain side difference was positively dependent on TMJ effusion and condyle marrow abnormalities, but negatively dependent on cortical bone abnormalities. Of the joints with effusion only one fourth showed osteoarthritis. Thus, there seems to be a subgroup of TMD patients showing more severe intra-articular pathology than disc displacement alone, and mostly without osteoarthritis. It should, however, be emphasized that patients with TMJ effusion and/or abnormal bone marrow in the mandibular condyle seem to constitute only a minor portion (less than one fourth) of consecutive TMD patients referred for diagnostic TMJ imaging. The majority of patients have internal derangement related to disc displacement, but without accompanying joint abnormalities. In patients with rheumatoid arthritis and other arthritides TMJ involvement may mimick the more common TMDs. Using MRI it is possible, in most cases, to distinguish these patients from those without synovial proliferation.

Relationship between sex, age, and the minimum thickness of the roof of the glenoid fossa in normal temporomandibular joints

et al. 2004

This autopsy study investigates the minimum thickness of the roof of the glenoid fossa of grossly normal temporomandibular joints (TMJ) and correlates this to gender and age. This study was based on 49 TMJ specimens collected from 26 male and 23 female cadavers whose mean age at death was 73.8 years (range=50-96). No information was available about TMJ symptoms before death. A digital micrometer was used to measure the minimum thickness of the glenoid fossae. Comparisons were made based on gender and age. The mean value for the minimum roof thickness of all joint specimens examined was 0.8 mm. Mean values for male and female specimens were 0.8 and 0.7 mm, respectively, which were not significantly different. In addition, no age-related differences were observed. The average thickness was 0.7 mm for individuals in their fifties, 0.8 mm for those in their sixties and seventies, 0.6 mm for those in their eighties, and 0.8 mm for individuals in their nineties. Although these data indicate that the minimum thickness of the glenoid fossa of the TMJ is not significantly correlated with sex or age in patients 50 years of age and older, they nonetheless provide additional information about normal TMJ anatomy, particularly with regard to our knowledge of joint remodeling and function in the disease and non-disease states. Thickness of the glenoid fossa has also been implicated as a factor in facial trauma involving superior displacement of the mandibular condyle into the middle cranial fossa. The thickness of the glenoid fossa is also of potential interest during surgeries involving the glenoid fossa, such as TMJ arthroplasty or joint reconstruction.
