Enticing Dimples: A Novel Observational Study Comparing the Preexisting Landmarks for Facial Dimple Creation Using 3D-Scanned Facial Images.

Abstract

Background  Dimpleplasty, a cosmetic procedure for creating dimples, is gaining popularity. However, the ideal site for dimple creation remains subjective. This study aimed to determine the optimal dimple placement using a three-dimensional (3D) model, reviewing panelists' preferences based on facial proportions and average ratings. Materials and Methods  A 3D model was used to assess three dimple placement points: Point A (intersection of the external canthus and Cupid's bow), point B (Khoo Boo-Chai point), and point C (site based on smile dynamics). Panelists reviewed these points on faces with different proportions using three facial ratios: ratio 1 (Tr-Me / lc r-lc l), ratio 2 (Tr-Nos / Nos-Me), and ratio 3 (Me-Lip / Lip-Nos). Panelists provided average ratings for each site based on aesthetic appeal relative to these ratios. Results  Point A received higher ratings for faces with a lower ratio 1 (wider faces). Point B was preferred in faces with higher ratio 1 (elongated faces) and lower ratio 2, receiving the highest average rating for balanced aesthetics. Point C was favored in faces with higher ratios 2 and 3, indicating dominance in the mid and lower facial thirds. Point B had the highest average rating overall. Conclusion  These results emphasize the importance of considering facial proportions for optimal dimple placement and individualized cosmetic outcomes. Simulation software like the one that we have used in our study, may further help in patient counseling before determining the site of dimpleplasty.
