Patients with central limitations, such as a long frenulum or a low anterior nasal spine, may not achieve the desired results from a lip lift without additional procedures.

A long frenulum restricts the elevation of the upper lip, which can be improved by cutting this fold to increase mobility.

Similarly, a low anterior nasal spine or a low-set caudal septum can create obstacles, potentially requiring nasal surgery for better lip lift outcomes and a more balanced smile.
