Aesthetics of numerical proportions in human cosmetic surgery (Assessment of nasolabial angle in patients undergoing rhinoplasty before and after surgery)

Abstract

Beauty is a universal phenomenon and debate over what constitutes beauty particularly beauty to human body, has raged since philosophy began. The beauty of individual features depends on "ideal" proportions, and it is suggested that expressing beauty in terms of geometry is possible. Assessment of some used parameters in facial surgeries and harmony of various facial features are essential to surgeon, who requires facial analysis. One of these parameters, is nasolabial 2 angle, in patients undergoing rhinoplasty. This study based on theoretical definitions of beauty and proportions performed the search for the application of this numerical proportions in modern cosmetic surgery. Present study has selected 23 samples (16 (69.5%) female and 7 (30.5%) male) from patients who undergoing rhinoplasty, By a surgeon. The nasolabial angle was measured in these patients from their lateral profile photographs with adobe Photoshop cc, pre and post surgery. Ideal post operative angle was 111.54 ± 26.5 degrees from this study. 18.8• increase in male and 14.68• increase in female is seen. There was no significant difference between men and women.

Morphometric analysis of pre and post operative facial angles following rhinoplasty

“…They observed that the mean nasolabial angle in men was 92.4 • and in women was 97.12 • , which increased post-operatively to 111.28 • in men and 111.81 • in women. 9 The results of our study are similar to theirs as our data shows a mean increase of 5.2±9.3 • following rhinoplasty.…”
