MRI as a method of evaluation and predicting mandibular growth based on temporomandibular joint

ConclusionClinically, the advantage of diagnosis of double contour is not to use any ionizing radiation related to scan in these subjects. Therefore, MRI could be a choice for the follow-up of growing patients.

CONCLUSIONS: It is suggested that ZTE-MRI provides clinically reliable images for bone assessment in TMJ disorder. MRI may become a beneficial diagnostic tool for patients with both TMJ disc and bone pathology, with advantages involving medical costs and radiation dose.

Tal, Berg / Boaz, FrenkelPage 816 - 820Preauricular swelling followed by limited mouth opening can be a challenging diagnosis. All anatomical structures and related pathologies should be examined. A 41-year-old woman presented to the Emergency Room complaining of limited mouth opening, severe pain that was worse on chewing, and swelling over her right temporomandibular joint (TMJ) that had started 3 days previously. Physical examination revealed localized swelling and redness over her right TMJ. Her right masticatory muscles were very painful and tender on palpation. Mouth opening was slightly limited. A computed tomograph...

DiscussionRadiographically, 2-D imaging is adequate to establish an initial radiographic diagnosis. However, more advanced modalities (computed tomography/magnetic resonance imaging [CT/MRI) are indicated to better evaluate the orientation of the tumor and assist in the surgical management. The 3-D imaging of the 3 cases presented here emphasize this point. Positron emission tomography/fluorodeoxyglucose (PET/FDG) imaging has also been recommended for specific cases. MRI may overestimate tumor aggressiveness secondary to the influence of bone marrow and soft tissue edema. The recognition of an osteochondroma is significant...

Conclusion: The method of using sutures to reposition and stabilize the articular disc for a patient with comminuted fractures is effective. There is great significance not only for patients with comminuted condylar fractures but for treatment of TMJ dysfunction especially for patients with high psychological pressure who persist in requiring the removal of metallic anchors although there are no clinical symptoms.

ConclusionsAs evaluated on MRI scans, no significant differences in the anatomic characteristics of the TMJ were detected between DDWR patients with or without concomitant arthralgia and the control group. There were no factors associated with the concomitant presence of arthralgia in patients with DDWR.

This study was approved by the Animal Experimental Ethics Committee of Southern Medical University, Guangzhou, China (2014-024). All experiments were performed under protocols to meet the requirements of the Association for Assessment and Accreditation of Laboratory Animal Care International and the Experimental Animal Center of Southern Medical University. Male cynomolgus monkeys (Macaca fascicularis) were used, preliminary power analysis being performed to get the proper sample size for three groups (G∗Power 3.1, Heinrich-Heine-Universität Düsseldorf, Germany; alpha = 0.05, power = 0.95; total N = 20 hem...

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 resear...
