“…In clinical practice, a fast spin echo sequence is used to obtain T2WIs because of its short acquisition time. Bae et al 18 attempted to evaluate the articular disc quantitatively in terms of the T1 relaxation time, T2 relaxation time, and T2 relaxation time. They used a 3.0 tesla MRI unit and the ultrashort time-to-echo imaging technique.…”

: The purpose of this study was to clarify the validity of measuring the signal intensities of cortical bone CB and temporomandibular joint TMJ discs on magnetic resonance MR images for the diagnosis of TMJ disease. Two investigations were performed. In the rst investigation, MR images of 13 TMJs of volunteers were obtained using a multi spin-echo sequence. Echo time TE was increased from 10 msec to 200 msec in steps of 10 msec. The signal intensities of the CB of the condylar head, and the anterior AD and posterior PD bands of the TMJ disc were measured, and their attenuation patterns were compared. In the second investigation, clinical MR images of 30 TMJs from patients with suspected TMJ disorders were selected. Proton density-weighted images PDWIs and T2-weighted images T2WIs were obtained at TEs of 14 and 85 msec, respectively, using a double-echo fast spin-echo sequence. The signal intensities of CB, AD, and PD were measured and compared with that of the external auditory meatus air using a Bonferroni test. AD and PD showed nearly identical signal intensity attenuation patterns. The signal intensities of AD and PD were lower than CB at TEs longer than 20 msec although they were higher at TEs shorter than 20 msec. Clinical PDWIs and T2WIs showed similar results. The signal intensities of CB, AD, and PD were signi cantly higher than the external auditory meatus air in both PDWIs and T2WIs. CB and TMJ discs show characteristic signal intensities, suggesting that the signal intensity measurement of these structures is valid.

“…It includes the TMJ, the maxillomandibular skeleton, the associated erupted and impacted teeth, the mastoid-styloid complex, the maxillary sinuses, and other findings such as external objects and piercings (Figure 2). A lateral cephalometric or anteroposterior radiograph can be used as well to document the maxillomandibular relation or discrepancies in anteroposterior dimension [3][4][5]. The CT scan of the head and neck is usually used as well to verify the relation of the maxillomandibular status with the base of skull.…”

“…A hard bony lesion of the joint, condyle, coronoid, or base of skull is investigated and can be seen in difficult situations. An MRI of the head and neck region is of great value to investigate the internal status of the TMJ region, showing the disk, effusion, and abnormal enlargements [5]. In addition to evaluating soft tissue abnormalities more clearly when compared to CT scans, it is useful if neurogenic, vascular, or mesenchyme disease is anticipated (Figure 3).…”

“…The use of 12.5 MHZ ultrasonography has been presented to be a useful aid for TMD evaluation with some limited application in detecting the presence or absence of derangements more than specifically identifying a precise type of the disease [6]. Some other investigatory tools have been used to help verify the status such as the stethoscope to listen closely to clicking or crepitus and the use of electromyography for objectively measuring the activity of some muscles of mastication especially temporalis and masseter but with limited application in the clinical field [4][5][6][7].…”

The main objective of this chapter is to introduce to the readers the issue of head and neck pain, temporomandibular joint (TMJ) disorders, clicking, headaches, migraines, and neck discomfort that are likely to present in the clinic with similar signs and symptoms. This chapter deals with the introduction, clinical examination, investigation, and the use of splint therapy, muscle complex injection therapy with botox and prolotherapy, TMJ lavage, arthrocentesis, and TMJ surgery to treat such patients.Headaches, Migraine, and TMJ Pain Management: Medical and Surgical Intervention http://dx.doi.org/10.5772/63381 113 Figure 3.

In vivo prediction of temporomandibular joint disc thickness and position changes for different jaw positions

Temporomandibular joint disorders (TMD) are common dysfunctions of the masticatory region and are often linked to dislocation or changes of the temporomandibular joint (TMJ) disc. Magnetic resonance imaging (MRI) is the gold standard for TMJ imaging but standard clinical sequences do not deliver a sufficient resolution and contrast for the creation of detailed meshes of the TMJ disc. Additionally, bony structures cannot be captured appropriately using standard MRI sequences due to their low signal intensity. The objective of this study was to enable researchers to create high resolution representations of all structures of the TMJ and consequently investigate morphological as well as positional changes of the masticatory system. To create meshes of the bony structures, a single computed tomography (CT) scan was acquired. In addition, a high-resolution MRI sequence was produced, which is used to collect the thickness and position change of the disc for various static postures using bite blocks. Changes in thickness of the TMJ disc as well as disc translation were measured. The newly developed workflow successfully allows researchers to create high resolution models of all structures of the TMJ for various static positions, enabling the investigation of TMJ disc translation and deformation. Discs were thinnest in the lateral part and moved mainly anteriorly and slightly medially. The procedure offers the most comprehensive picture of disc positioning and thickness changes reported to date. The presented data can be used for the development of a biomechanical computer model of TMJ anatomy and to investigate dynamic and static loads on the components of the system, which could be useful for the prediction of TMD onset.
