Definition of mandibular measurements and MR correlates. 1A: Three-dimensional reconstruction of the mandible with craniofacial points and distance measurements. Points: (1) Gnathion (Gn): the most anterior–inferior point of the mandible; (2) Gonion (Go): The left and right Go are the most posterior and inferior points of the mandible. Distances measured: (1) Mandibular body length (solid lines): the distance from Gn to the left or right Go; (2) Mandibular width (dotted line): the 2-dimentional measurement of the width of the lower portion of the mandible. It is the distance between the left and right Go; (3) Mandibular depth (dashed line): the distance from Gn to H, where H is the midpoint between the left and right Go. 1B: The axial MR slice containing the Gn. 1C: The axial MR slice containing the left and right Go.
