Orbitomeatal basal line-anthropological basal line (OML-ABL), and the acanthiomeatal line (AML)-ABL crossing angles were measured using profile pictures. There were 219 volunteers in total: 42 people four years old, 44 people nine years old, 45 people 14 years old, 43 people 19 years old, and 45 people 40 years or older (48±7.4 years). The average OML-ABL crossing angle was 14.3 degrees in the 4-year-old group, while that of the 40-year or older group was 11.1 degrees. The deviation width of the 4-year-old group was 4.8 degrees, and that of the 40-year or older group was 2.4 degrees. The average AML-ABL crossing angle was 12.3 degrees in the 4-year-old group, while that of the 40-year or older group was 15.7 degrees. There were differences between males and females. The deviation width of the 4-year group was 5.4 degrees, and that of the 40-year or older group was 2.7 degrees. The results showed that 14.0 degrees for around 4-year-old, and 12.0 degrees for around 9- to 14-year-olds, could be used as OML-ABL crossing angles as a practical proposition.
