Determination of the most accepted facial angles and anterior-posterior chin position in patients ‎seeking cosmetic surgery in Shiraz, Iran

Beauty standards are related to race and change over time with cultural changes. The criteria obtained for a specific race cannot be used as treatment planning criteria for other races and societies. It seems that no thorough study has been carried out in Iranian context to determine the acceptability of these standards. In this study, the desired nasolabial (NL), nasofrontal (NF), chin-neck (Ch-N) angles and anterior-posterior chin position from the point of view of people seeking esthetic surgery were determined. In a cross-sectional, descriptive study, 500 people seeking esthetic surgery referring to School of Dentistry and Chamran Hospital in Shiraz, Iran, were asked to see images and record their desired angles in a questionnaire. The samples were chosen from people with ages ranging from 18 to 48 years old referred to t-he Hospital in 2012 and 2013. The silhouette profile image of a young girl with normal face ratios was used. Data were analyzed via SPSS software using chi-square and t-tests. Chi-square test was used to compare nominal data and student’s t-test to compare quantitative data. P < 0.050 was considered as significant. The mean age of subjects in our study was 27 years. From the 500 subjects, 35.4% were males and 64.6% were females. Average desired Ch-N, NL and NF were 118.28, 137.8 and 107.8 respectively. Desired mean for the anterior-posterior chin position was 6.23 mm. According to this study, no significant differences were found between the desired face sizes in Iranian community and other communities.
