The rational of forehead lifting in patients with chronic facial paralysis

Abstract

The incidence of permanent facial sequels in patients with Bell’s palsy is about 30 % and results in impaired mimic expression of both midface and forehead in varying degrees. Even at rest, most patients experience an imbalance of their facial features. In this article, static correction of brow imbalance was evaluated in patients with sequels after unilateral facial palsy. Thirty-one patients with sequels of Bell’s palsy underwent surgery with endoscopic forehead lift. Brow position was geometrically assessed pre- and postoperatively. The validated self-assessment instrument for quality of life [Short Form 36(SF-36)] was completed prior to and after surgery. The follow-up period was 12 months. A notable improvement in the position of the brows was demonstrated over time with lasting results. All patients experienced an improvement in facial symmetry and balance at rest. However, no significant difference could be shown using SF-36 pre- and postoperatively. Endoscopic forehead lift combined or as an isolated procedure is a valuable instrument to correct sequels of Bell’s palsy. Level of Evidence: Level IV, therapeutic study.
