Abstract

OBJECTIVE: To determine if clinically used botulinum exotoxin A (Botox) injections to the forehead and glabellar and crow's-feet regions result in modifications of eyebrow position. DESIGN: Prospective study. SETTING: Academic medical center in St Louis, Mo. SUBJECTS: Twenty-nine adult patients treated with botulinum exotoxin A injections for rhytids. INTERVENTION: The eyebrow position at 13 different sites was measured before injection and 2 weeks after treatment. The areas injected were based on patient preference and physician assessment. Of the 29 patients, 14 received injections into the glabella only and 15 received injections into the glabella and forehead, with or without treatment of the crow's-feet. RESULTS: In 29 patients at rest, we found no significant (P value range,.17 to.97) change in eyebrow position, except for a point depression at the right lateral eyebrow. The 15 patients who received injections into the forehead and glabella, with or without treatment of the crow's-feet, had no significant (P value range,.11 to.84) change in eyebrow position, except for a point of depression at the left medial eyebrow. Both groups exhibited eyebrow depression in the active state (eyebrow maximally elevated). CONCLUSIONS: Botulinum exotoxin A injections into the forehead and glabellar, and crow's-feet regions did not significantly change the resting eyebrow position. However, forehead injections contributed to eyebrow depression in the active state.
