- Fig 1.
A and B, Axial source images of the 3D-DESS-WE sequence. C and D, Coronal reformatted images of the 3D-DESS-WE sequence. Axial image shows the masseteric nerve (A, arrow) and buccal nerve (A, solid arrowhead) arising from the V3 trunk. The intermediate point is established, where the masseteric nerve enters the deep surface of the masseter muscle (B, arrow), to divide the nerve into proximal and distal portions. The intermediate point for the buccal nerve is established as the anterolateral edge of the lateral pterygoid muscle (B, solid arrowhead). Reformatted coronal images show the course of the buccal nerve running inferiorly (C, arrows) and the auriculotemporal nerve running inferolaterally (D, arrows). The intermediate point is established where the auriculotemporal nerve enters the pterygoid venous plexus (B and D, open arrowheads).

A and B, Coronal reformatted image of the 3D-DESS-WE sequence. C, Axial source image of the 3D-DESS-WE sequence. Reformatted coronal images show the lingual nerve (A, arrows) and the inferior alveolar nerve (B, arrows). The intermediate points are established where the lingual nerve running laterally starts to change direction medially (A, arrowhead) and where the inferior alveolar nerve enters the mandibular foramen (B; arrowhead). Axial image shows that the mylohyoid nerve runs at the medial surface of the mandible (C, arrow). The intermediate point is established where the nerve enters the mylohyoid muscle (C, arrowhead).
