Positive and negative values were assigned to measurements made where the lateral border of the frontalis was located medially and laterally to L2, respectively. L2 is defined in terms of FT (the most protruding point of the frontotemporal region), L0 (the line connecting the infraorbital margin with the tragus), and L1 (the line parallel to L0 and passing through FT) such that L2 is positioned 45° from L1 and passes through FT. SD, standard deviation. ^aSections 1 to 9 were defined as distances of 0 to 1, 1 to 2, 2 to 3, 3 to 4, 4 to 5, 5 to 6, 6 to 7, 7 to 8, and 8 to 9 cm from FT along L2, respectively. ^bIt was not possible to calculate an SD for this measurement because it corresponded to only 1 sample.
