“…However, there is no gold standard or standardized method, as each method has its own pros and cons (27). The Internet-based survey that was used had several advantages (23). This method increased the data collection (rater count) and rate of data accrual and analysis; the results were reproducible and logistical and monetary obstacles were eliminated.…”

Objective To assess the changes in the Facial Attractiveness (FA) in two groups of cleft lip and palate patients with Class III malocclusions treated using LeFort I surgery or late maxillary protraction. Materials and Methods Standardized pre- and post-treatment photographs were taken of 32 patients (17 corrected by orthognathic surgery and 17 by late maxillary protraction). The photographs were randomized and 42 clinicians and 121 laypeople rated them on a 10-point FA scale via a web-based survey. Results Clinicians’ mean FA values increased from 4.45 to 5.16 [95% CI of Mean Difference (MD), 0.59–0.82, p<0.001] in surgical cases and 4.84 to 5.30 (95% CI of MD, 0.35–0.56, p<0.001) in protraction cases. The laypeople mean FA values increased from 5.07 to 5.54 (95% CI of MD, 0.40–0.53, p<0.001) in surgical cases and 5.51 to 5.68 (95% CI of MD, 0.11–0.23, p<0.001) in protraction cases. When patients combined, laypeople rated FA 0.64 points higher (95% CI, 0.54–0.74, p<0.001) in pre-treatment and 0.38 points higher (95% CI, 0.27–0.48, p<0.05) in post-treatment relative to clinicians. Conclusion Both clinicians and laypeople perceived an improvement of FA after both treatments. Laypeople rated FA higher compared to clinicians.

“…To our knowledge, the present study is the first to identify both an ideal NTP and nasal tip rotation using a populationbased method that involves online social-network volunteers, a method validated in previous work. 9,10 In the present study we also used a novel method for assessing facial attractiveness that is an established business and marketing analytic (paired comparison analysis). 11 This method allows the researcher to convert subjective pairwise comparisons into relative quality scores or preference ranks.…”

IMPORTANCE There is no universally accepted quantitative metric that defines the ideal nasal tip rotation and projection. OBJECTIVE To identify the ideal nasal tip projection (NTP) and rotation by using 3 classic NTP methods (Crumley 1, Crumley 2, and Goode). DESIGN, SETTING, AND PARTICIPANTS Lateral facial portraits of normal-appearing white women aged 18 to 25 years were selected from a previously validated and attractivenessscored database of images. Each image was digitally modified to fit the NTP ideals outlined by the Crumley 1, Crumley 2, and Goode methods with columellar facial angles (rotation metric) of 96°, 101°, 106°, 111°, and 116°(15 modified images per portrait). These variants were incorporated into electronic surveys that were distributed to traditional focus-group and online social-network participants. Analysis was performed using paired comparison analysis, a consumer preference research analytic. The traditional focus-group participants were undergraduate students at the University of California, Irvine, whose online social-network contacts were also used. MAIN OUTCOMES AND MEASURES Mean ranks.RESULTS There were no significant differences in preference between the traditional focus-group (n = 106) and online participants (n = 3872) (P > .05). The most preferred rotation variant for all 3 NTP methods was 106°(Crumley 1: mean rank, 2.11 [95% CI, 2.07-2.16]; Crumley 2: mean rank, 2.07 [95% CI, 2.02-2.12]; and Goode: mean rank, 2.05 [95% CI, 1.99-2.11]; P < .001). Crumley 1 was considered to be the most attractive NTP method (mean rank, 1.84 [95% CI, 1.82-1.85]; P < .001) overall and was the most preferred NTP method for faces of above-average attractiveness (mean rank, 1.78 [95% CI, 1.76-1.80]; P < .001). No significantly preferred NTP method was found for faces of average attractiveness (P > .05). The most aesthetic combination of tip rotation and projection was a columellar facial angle of 106°with the Crumley 1 tip projection. CONCLUSIONS AND RELEVANCE To our knowledge, this is the first population-based study to attempt to simultaneously determine the ideal NTP and rotation. Each classic NTP method uses measurements dependent on both projection and rotation; thus, ideal rotation for each NTP method must be determined before comparison of the ideals. A rotation of 106°( columellar facial angle) was found to be the most aesthetic. The Crumley 1 method was determined to be the most attractive nasal tip variant overall. LEVEL OF EVIDENCE NA.

“…It should be noted that this study focused primarily on validating this methodology in lateral morphing in hopes to create a systematic approach for future research in lateral facial quantification studies. Future studies will emulate our previous work [2,11,12,13] and will require more than 100 synthetic morphs in order to achieve profound statistical power and narrow confidence intervals.…”

“…These variances require manual registry point placement for realistic morphing outcomes, and this does require training and expertise. Prior studies in our lab utilized a trial and error approach honed over hundreds of morphing exercises to identify distinct points that are readily identifiable to produce realistic images [2,[10][11][12][13]. Similar to CAD/CAM software manual input of proper margin outlines for CERAC crowns.…”
