This study evaluated the efficacy of botulinum toxin A (BTX A) in improving the aesthetic appearance of lips. Twenty-four outpatients with clinical evidence indicating decreased fullness of lips or gummy smile were selected and received BTX A injection on the orbicularis oris. We observed a significant decrease in wrinkles and improvement in gummy smile in all patients 4 weeks after the injection. Aesthetic lines also changed significantly. Local injection of BTX A on the orbicularis oris could simultaneously achieve mild lip enhancement, improvement in fine wrinkles around lips, and mild gummy smile.
本研究评估了A型肉毒毒素（BTX A）改善唇部美观的疗效。选择了24例有临床证据表明唇部丰满度降低或露龈笑的门诊患者，并在口轮匝肌上注射BTX A。注射后4周，我们观察到所有患者的皱纹明显减少，露龈笑得到改善。美学线条也有显著变化。在口轮匝肌上局部注射BTX A可同时实现唇部轻度丰满、改善唇部周围细纹以及减轻露龈笑。
