Figure 2: (a) Surface marking showing line L1 and L2 and (b) the measuring points on the two standard lines. LBC- Lateral bony canthus, L1 line connecting the lateral bony canthus to the upper level of the tragus, L2 line perpendicular to L1 at lateral bony canthus, N1 point where anterior rami of FTFN crossed L1, middle rami N2 and posterior rami N3 point, F- distance from LBC to where the upper most nerve crossed L2, A1 distance between lateral bony canthus to where the frontal branch of STA crosses the L2.
