“…Both GM and retro discal tissue were included in the region of interest. The sizes and position of the ROIs were determined according to the method of Yajima et al, (25) For each measurement, a 3 mm square ROI was placed over the retro discal tissue. A 6mm square ROI were drawn over the GM and placed closest to the mandibular condyle (Figure 1).…”

Temporomandibular disorders (TMD) is a broad term referring to pain and dysfunction of temporomandibular joint (TMJ), nmasticatory muscles and its associated structures. TMD is the most common orofacial pain condition with prominent feature like regional pain in the face and preauricular area during static and dynamic movements. Methods of assessing clinical pain were subjective and not affirmative. There still remains element of drafting the clinical pain evaluation in TMD patients. This study correlated the pain range in TMD patients with the levels of signal intensity (SI) in FLAIR MRI (Fluid Attenuation Inversion Recovery magnetic resonance imaging) to devise an objective pain assessing system based on the SI values. Settings and design: The present study is institution based, observational cross sectional study. A 32 temporomandibular joints were evaluated in the study. Before imaging, subjective pain score were recorded using Visual Analog Scale (VAS). In FLAIR MRI, both grey matter and retro discal tissue were included in the Region of Interest and the SIRs were calculated. SIRs in painful temporomandibular joints were correlated with Visual Analog Scale score. Unpaired t test was used to compare the mean values recorded for SIR. P-value <0.05 is considered to be statistically significant. Study results shows that SIRs of retrodiscal tissue were significantly increased in patient with higher VAS score (p<0.05). Retrodiscal tissue in painful proteinous elements. Keywords: Temporomandibular disorders, Signal intensity, FLAIR MRI, Retrodiscal tissue

“…This might occur due to the laxity of the ligamentous apparatus of the temporomandibular joint, or inactivation of the muscles involved in the depression of the mandible. It is important to measure the range of mandible opening movement until the first pain is being felt [ 22 , 23 ].…”

“…Testing the functional capacity of the joints based on the range and symmetry of joint movements is a source of valuable diagnostic information. Functional abnormalities can exist due to disorders in the functioning of the joint system [ 1 , 3 , 5 , 8 , 9 , 15 , 22 , 25 ].…”

“…MR imaging is a precise diagnostic tool to examine soft tissues in the TMJ area, specifically the position of the articular disc. It offers numerous advantages, including high image resolution, selectable imaging planes, a low number of bone-related artifacts, 3D images and absence of patient exposure to ionizing radiation [ 8 , 9 , 18 , 22 , 29 ].…”

Diagnostic of Temporomandibular Disorders and Other Facial Pain Conditions—Narrative Review and Personal Experience

Temporomandibular disorders are complex dysfunctions of masticatory muscles and temporomandibular joints. Their symptoms affect more than 40% of the population and their prevalence is rising. It is important to establish a unified protocol for this specialistic examination. This review describes the authors’ own longstanding experiences and the discrepancies in the current literature regarding this topic as well as a detailed procedure of diagnosing temporomandibular disorders including the leading but often underrated role of a medical interview. We presented optimal physical examination methods as well as specific situations in which additional diagnostic and imaging tools may be useful. The emphasis was put on the importance of differential diagnosis between temporomandibular disorders and other diseases presenting with similar symptoms.

Diagnosis of retrodiscal tissue in painful temporomandibular joint (TMJ) by fluid-attenuated inversion recovery (FLAIR) signal intensity

Abstract: FLAIR sequences provide a high signal in patients having painful TMJ, and it suggests that retrodiscal tissue in painful TMJ contains elements such as protein.
