Assessment of Ideal Dimensions of the Ears, Nose, and Lip in the Circles of Prominence Theory on Facial Beauty.

IMPORTANCE

A theory on facial beauty might allow clinicians to achieve better results.

OBJECTIVES

To find the ideal vertical position of the ears, total lip length, lip pucker length, distance between the irises, and starting point for the nasal radix.

DESIGN, SETTING, AND PARTICIPANTS: In this subjective survey, 11 sets of 43 total digitally adjusted pictures (DAPs) and line drawings of actual faces were ranked based on attractiveness by 419 clients at a facial plastic surgery clinic. The data were collected from July 13 to August 29, 2015, and were analyzed from September 17, 2015, to March 21, 2016.

MAIN OUTCOMES AND MEASURE

Six groups of line drawings and 5 groups of DAPs of an actual person were used to test the ideal position of the ears to determine whether the face is organized into oblique and parallel relationships and whether the total lip length and the lip pucker length are associated with multiples of an iris width (IW), and to determine the start of the nasal radix and its association with the superior margin of the iris and distance between the irises.

RESULTS

Of the 419 survey respondents, the ear aligned with the second oblique was considered the most ideal by the participants. The preferred total lip length was 4.0 IWs in the DAPs and 5.0 IWs in the line drawings. For the lip pucker length, 2.0 and 3.0 IWs were considered the best. The ideal start of the nasal radix was tangential with the superior margin of the iris. The distance of 5.5 IWs from iris to iris and 3.0 IWs from the horizontal level of the iris to the nasal tip was preferred.

CONCLUSIONS AND RELEVANCE

The face may be ideally organized into 3 parallel obliques. The IW, horizontal aperture of the eye, and then iris to iris distance may best determine the size and shape of progressively larger objects in the face. The absolute position of the eye was considered important by the participants in the ideal positioning of other objects in the face.
