This study was proposed to analyze the changes in shape and position of the eyebrow before and after botulinum toxin A injection using two different protocols for a periorbital rejuvenation.
The botulinum toxin A treatment was performed for brow-lift and effacement of crow's feet (group A), and for brow-lift and effacement of glabellar frown lines in addition to crow' feet (group B). To evaluate the change in brow shape and height, measurements of five points around the brow were taken before and after treatment.
In groups A and B, the brow positions were elevated, and the interbrow distance was increased. The central brow showed the largest elevation, followed by the lateral brow and the medial brow. The difference in the interbrow distance between groups A and B was statistically significant (p < 0.001).
Elevation of the eyebrow with the desired aesthetically pleasing curvature was obtained after botulinum toxin A treatment in both groups using two different protocols for periorbital rejuvenation. The effect on the muscular dynamics after treatment can be changed according to the amount and the injection points. Therefore, in determining the injection protocols for periorbital rejuvenation, consideration should be given to the change in brow position and shape according to the change in the muscular dynamics after treatment.
本研究旨在分析使用两种不同方案进行眶周年轻化治疗时，注射A型肉毒毒素前后眉毛形状和位置的变化。
对A组进行A型肉毒毒素治疗以提升眉毛并消除鱼尾纹，对B组进行A型肉毒毒素治疗以提升眉毛、消除眉间皱纹以及鱼尾纹。为评估眉毛形状和高度的变化，在治疗前后对眉毛周围的五个点进行测量。
A组和B组中，眉毛位置均升高，眉间距离增加。眉中央升高幅度最大，其次是眉外侧和眉内侧。A组和B组眉间距离的差异具有统计学意义（p < 0.001）。
两组使用两种不同方案进行眶周年轻化治疗后，通过注射A型肉毒毒素均获得了具有理想美观弧度的眉毛提升效果。治疗后对肌肉动态的影响可根据注射量和注射点而改变。因此，在确定眶周年轻化治疗的注射方案时，应考虑治疗后肌肉动态变化导致的眉毛位置和形状改变。
