Enhancing Perioral Aesthetics: The Role of Orbicularis Oris Muscle Suspension in Deep Plane Lip Lifts.

The deep plane lip lift is designed to rejuvenate the lips by enhancing both incisive display and vermillion show. This study aims to quantify the effect of orbicularis oris muscle plication on these 2 features during a deep plane lip lift. Findings revealed a consistent inverse 1:1 relationship between vermillion show and incisive display following plication-each 1 mm increase in incisive display corresponded to a 1 mm decrease in vermillion show. These results suggest that orbicularis oris muscle plication can be strategically employed during a lip lift to precisely refine lip aesthetics.
