Abstract

The author measured the vertical dimension and the distances from Trichion to Nasion of 825 Korean adults (414 of male, 411 of female) above 21 years of age by Willis gauge. The following results were obtained. 1) The distances from subnasale to the bottom of chin were 71.4mm in male and 68.7mm in female, and those from Trichion to Nasion were 70.4mm in male and 68.0mm in female. The former were longer than the latter, and the distances in male were longer than those in female. 2) The differences between the distances from Subnasale to the bottom of chin were 1.0mm in male and 0.7mm in female. The frequencies of percentages, in which differences between the distances mentioned above were 0±1mm, were 43.0% in male, 42.6% in female, and 42.8% in total. 3) With the matter of age and sex differences, the distances from Subnasale to the bottom of chin and those from Trichion to Nasion were increasing to 31-40 age group by age, but those had a tendency of decreasing in the late age in both sexes.
