Abstract
BACKGROUND: Contemporary lip augmentation has evolved from simple volumization techniques to more intricate contour-specific enhancements. Among these advancements, the Modified Cupid's bow lips, characterized by their distinctive Cupid's bow shape and vertical projection, have gained significant popularity as a prominent aesthetic trend. AIMS: This study aims to evaluate the prevalence of patient preference for the Modified Cupid's bow lips contour and to propose a systematic approach for its clinical implementation based on retrospective analysis. METHODS: A retrospective analysis was conducted, including 67 consecutive female patients seeking primary lip augmentation. Demographic information and preferences regarding lip contours were statistically analyzed using chi-square tests with age stratification. Anthropometric measurements of labial tubercle area and upper lip angles were performed using Image Pro Plus software for quantitative assessment. RESULTS: This analysis revealed that 42 patients (62.7%) preferred Modified Cupid's bow lips, a significantly higher proportion compared to the 25 patients (37.3%) who favored natural lips (χ(2) = 4.31, p = 0.038). In addition, a significant correlation was found between age group and lip preference (χ(2) = 8.74, p = 0.033), with the highest preference for Modified Cupid's bow lips (73.9%) that was observed in the 31-40 year age group. Morphometric analysis demonstrated statistically significant post-treatment increases in labial tubercle area (228.5 ± 169.6 mm(2) vs. 297.0 ± 157.3 mm(2), p = 0.039) and alterations in key angular measurements (Angle γ, δ, ε; p < 0.05), confirming enhanced central projection, vertical height, and contour definition. CONCLUSION: The Modified Cupid's bow lips represent a dominant aesthetic preference and necessitate specialized injection techniques and an understanding of anatomy for optimal results. Objective morphometric changes validate the efficacy of the technique in achieving defined lip contours.
