a
For depth both left and right-sided measurements were analysed. The landmarks are as defined in Table 1 (ans: anterior nasal spine, gl: glabella, m: mastoidale, na: nasion, p: preaurale, sn: subnasale, zy: zygion). Values shown are means ± (standard error of mean) SEM.
b
Statistically significant; p-values are from unpaired two-tailed t-test.
