Impact of Glabellar Injection Technique With DaxibotulinumtoxinA for Injection on Brow Position

Area of Science:

• Aesthetic medicine
• Dermatology
• Ophthalmology

Background:

• Botulinum toxin type A injections are commonly used for glabellar lines.
• Suboptimal eyebrow position is a potential complication of glabellar injections.
• Precise injection technique is essential for achieving desired aesthetic results.

Purpose of the Study:

• To evaluate the impact of glabellar injection technique on eyebrow position.
• To assess outcomes with DaxibotulinumtoxinA for Injection (DAXI).

Main Methods:

• Retrospective analysis of 60 adults treated with DAXI 40 U.
• Standardized facial photography and measurement of brow displacement.
• Evaluation of brow position by an oculoplastic surgeon and anatomist.

Main Results:

• Variability in injection location, depth, and resulting brow position was observed.
• Positive outcomes associated with deep medial corrugator, superficial lateral corrugator, and deep midline procerus injections.
• Targeted corrugator injections correlated with longer treatment duration.

Conclusions:

• Precise injection targeting corrugator supercilii and procerus muscles, avoiding frontalis, yields aesthetically pleasing brows.
• Optimized injection patterns enhance efficacy duration.
• Anatomically precise injections improve patient outcomes in glabellar treatments.
