CUPID Lip Lift: Advanced Lip Design Using the Deep Plane Upper Lip Lift and Simplified Corner Lift

BACKGROUND: Upper lip lift is achieved with a variety of techniques but many questions remain about the benefits and drawbacks of each technique. The CUPID deep plane or modified upper lip lift procedure has recently been introduced to help mitigate risk and optimize outcomes. OBJECTIVES: The aims of this study were: (1) to better characterize and simplify the complex and artistic decision-making process involved in upper lip lift and corner lip lift; (2) to present a mathematical guide to maintain the natural balance of the upper lip, optimizing muscle function, and to indicate when to add a corner lift; and (3) to elucidate design elements, aging, and future treatment considerations. METHODS: A PubMed (United States National Library of Medicine, Bethesda, MD) search was performed in October 2021 for all journal articles published on upper lip lift and corner lip lifts. The search covered from 1950 to the present day in all languages and without exclusion criteria. Outcomes and the evolution of deep plane upper lip lift design over the last 6 years were analyzed. RESULTS: By following the patterns demonstrated in over 2440 consecutive lip lifts, the authors have been better able to understand the nuances involved in proper design that will avoid acceleration of aging and exaggeration of appearance, and reduce the need for revision while maximizing results. CONCLUSIONS: Upper lip lift design is more complex than most practitioners realize. The mathematical concept described herein makes it possible to obtain more aesthetically pleasing and consistent outcomes. This novel approach to lip lift design enables the practitioner to improve lip balance, facial harmony, and tooth show, and obtain adequate exposure of the lateral vermillion.
