Luxation des Discus articularis des Kiefergelenks

Assessment of

anterior positioning splint in conjunction with lateral pterygoid BTX injection to treat TMJ disc displacement with reduction — a preliminary report. Image showing a graphical representation of the point system used to locate the articular disc on the MRI (adapted from Arayasantiparb et al. [1] [top]). MRIs of one of our patients, preoperative left and postoperative left. Red points identify the T (lowest point of eminence will mark (0,0) on the (x,y) graph) and GP (posterior glenoid tubercle) (will mark (10,0) point of the (x,y) graph to be drawn). The discs are coloured for visualization [bottom]. Point DA, anterior-most convexity of the articular disc; point DP, posterior most convexity of the articular disc; point C, uppermost point of the mandibular condyle; point GP, lower-most point of the posterior glenoid tubercle; point A, uppermost point of the external auditory meatus

Assessment of

functional improvement with temporalis myofascial flap after condylectomy in elderly patients with anterior disc displacement without reduction and an erosive condylar surface. Representative MRI of ADD without reduction and an erosive condylar surface of TMJ. a and b The shape and length of the disc (white arrows) was also deformed in the closed and open mouth positions

Correlation

between temporomandibular joints and craniocervical posture in patients with bilateral anterial disc displacement. Craniocervical reference planes used in this study 1.Nasion-sella line (NSL, plane through nasion and sella); 2. Frankfort horizontal plane (FH, plane through porion and orbitale); 3. Nasal line (NL, line through the posterior nasal spine and anterior nasal spine); 4.Mandibular line (ML, a line tangent to the lower edge of the mandible); 5. Ramal line (RL, tangent of posterior margin of mandibular ramus); 6. Odontoid process tangent (OPT, the tangent of posterior second cervical vertebral); 7. OP (Odontoid plane, the tangent of anterior second cervical vertebral); 8. CP (Cervical plane, vertically bisect the line of the second cervical vertebral body); 9. C2’ (The tangent of the lower edge of the second cervical vertebra); 10. MGP (McGregor’s line, the line from the posterior edge of the hard palate to the lowest point of the occipital squama)
