Clinicians and laypeople assessment of facial attractiveness in patients with cleft lip and palate treated with LeFort I surgery or late maxillary protraction

Abstract

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.

Measuring attentional bias in children with prominent ears: A prospective eye-tracking study

“…When viewed by naïve observers, overt facial lesions, such as cutaneous malignancies 16 and midface retrusion secondary to cleft lip and palate, 17 have been correlated with lower facial attractiveness. In addition, faces with facial nerve paralysis have been associated with negative affect display by observers.…”

Applying artificial intelligence to assess the impact of orthognathic treatment on facial attractiveness and estimated age

“…Professional appraisal of attractiveness, as performed by orthodontists, surgeons or general dentists, relies on taught rules of beauty dictated by 'ideal' facial features, golden ratios and other established proportions [11][12][13] . These classic rules of facial harmony will, however, not reflect the attractiveness as perceived by peers [14][15][16] . Conversely, the assessment of attractiveness performed by a limited number of lay people remains equally inconclusive.…”

Apriori feasibility testing of randomized clinical trial design in patients with cleft deformities and Class III malocclusion

“…There may be many social obstacles to randomized care. As both treatments have the potential to significantly alter the patient's facial aesthetic [16], the choice of treatment usually involves prior discussion. Teenagers often ask questions about orthognathic surgery and maxillary protraction, the potential benefits and co-morbidities.…”
