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
