Ideal Back and Buttock Height Proportions in High-Definition Buttock Contouring

Background: High-definition body sculpting expects the adoption of contour lines that adhere to ideal proportions. In high-definition buttock contouring specifically, there remains a lack of guidance for ideal buttock height proportions. Interestingly, a disproportionately lower number of Brazilian buttock lift (BBL) surgeries are being completed by Caucasian patients. This disinterest may partially be attributed to their dislike of exaggerated buttock sizes following BBL surgery. However, to date, ideal buttock height proportions have not been established for Caucasian clients. Objective: We determined to clarify the ideal back-to-buttock height proportions in Caucasian patients desiring buttock enhancement. Methods: We examined 10 Caucasian models to establish the ideal back-to-buttock-to-upper-leg height ratios. We then compared this presumed ideal standard to 20 Caucasian patients desiring buttock enhancement. Results: We determined that the ideal back-to-buttock-to-upper-leg height proportions for Caucasian models measured 40:25:35, respectively. The back-to-buttock-to-upper-leg height proportions of Caucasian patients desiring buttock enhancement were noted to be 48:25:37. The back-height proportion was found to be significantly longer, and the upper-leg height was significantly shorter in actual patients when compared to the models. Interestingly, the buttock height proportion was nearly identical between the groups. These findings demonstrated statistically significant differences but, more importantly, a similarity that might clarify why Caucasian patients are less likely to desire buttock enhancement. Conclusion: The decreased interest in buttock enhancement by Caucasian patients may stem from the fact that their buttock proportions mimic those set by model standards. The actual discrepancy in height proportions stems from a longer back and shorter upper legs in patients seeking buttock enhancement. **Level of Evidence: Level IV, Evidence from Multiple Case Studies
