ABSTRACT
In order to evaluate the aesthetic triangle of the face in Tai adults, we measured the vertical nasal height and the lower facial height of 200 subjects by using the sliding caliper. There were 100 males and 100 females who had never had nasal surgery or severe nasal injury. Their ages ranged from 15-65 years old. The mean body height in males was 165.5 + 6.2 cms; in females, 155.4 + 5.2 cms; the mean body weight in males was 58.2 8.0 kgs; in females, 52.4. The study showed that the average vertical nasal height in males was 5.1 + 0.3 cms; in females, 4.8 + 0.3 cms; the average lower facial height in males was 6.6 + 0.4 cms; in females, 6.3 + 0.4 cms. Statistical analysis revealed significant differences of the two parameters measured between males and females. There was significant correlation between the lower facial height with body weight and body height only in Thai males.
