The importance of the retaining ligamentous attachments of the forehead for selective eyebrow reshaping and forehead rejuvenation.

Background: Forehead rejuvenation procedures can lead to excessive elevation of the medial brow, resulting in the "surprised look." Differential treatment of the medial and lateral brow allows more precise positioning. The purpose of this study was to determine whether retaining structures exist in the forehead that would permit this differential elevation.
