The standard angle between the longitudinal axis of the ear and the bridge of the nose in Thai women.
A photographic technique was used to measure the angle between the longitudinal axis of the ear and the bridge of the nose of 619 Thai women, aged 15 to 25 years, from all 6 regions of Thailand, and that of beautiful Thai women subjects to determine the most desirable angle. This was done to test the validity of the hypothesis which postulates that the longitudinal axis of the ear should be parallel to the bridge of the nose, and to compare this angle with those determined from studies in other countries to determine national differences. It was also desired to determine the angle that looks best and appears to be most aesthetically pleasing from evaluation of questionnaires. It was found that the longitudinal axis of the ear is not parallel to the bridge of the nose, and that the angle in Thai women should be 19.3 +/- 5.5 degrees to provide both proper and aesthetic placement of the reconstructed ear. There is no statistically significance difference in this angle among the population of all regions of Thailand and the beautiful subjects. However. Thais, Japanese and Americans have different angles, so it appears that each nationality has its own normal value for this angle.
