Summary
Botulinum exotoxin A (Botox) injections to the face do not significantly alter resting eyebrow position. However, forehead injections can cause eyebrow depression when the eyebrows are actively raised.
Area of Science:
- Dermatology
- Cosmetic Surgery
- Facial Aesthetics
Background:
- Botulinum exotoxin A (Botox) is widely used for cosmetic facial rejuvenation.
- Understanding its precise effects on facial anatomy, such as eyebrow position, is crucial for optimal outcomes.
Purpose of the Study:
- To investigate the impact of Botox injections in the forehead, glabella, and crow's-feet regions on eyebrow position.
Main Methods:
- Prospective study involving 29 adult patients receiving Botox injections.
- Eyebrow position was measured at 13 sites before and 2 weeks after treatment.
- Patients received injections based on preference and physician assessment.
Main Results:
- No significant changes in resting eyebrow position were observed across all patients.
- Minor depressions were noted at specific lateral or medial eyebrow points in subgroups.
- Forehead injections, combined with glabella injections, led to eyebrow depression in the active (elevated) state.
Conclusions:
- Botox injections in the forehead, glabella, and crow's-feet areas do not significantly alter resting eyebrow position.
- Forehead injections may contribute to eyebrow depression during active facial expressions.
