Novel applications and injection sites for Botox are continually evolving. This study aimed to analyze Botox outcomes for various injection sites to differentiate treatments that consistently yield impressive results from those that produce less patient satisfaction. The change in the prevalence of Botox usage for each facial subsite over a 2-year period also was evaluated.
A retrospective chart review was performed for 60 patients who received Botox injections in a private cosmetic surgery practice. Patients were sampled from 24-month periods 2 years apart. The information collected included dosing and injection intervals and patterns. The outcomes analyzed included the prevalence of injections by subsite and the retention rate.
The most frequently injected subsite was the glabellar region. The findings showed an impressive trend toward increasing numbers of patients receiving treatment of the superolateral orbicularis oculi (57-80%) and the depressor anguli oris (10-20%).
Botox injection for facial rejuvenation has an excellent track record for patient satisfaction. The prevalence of treatment for the traditional injection sites was very stable over the measured period. The study findings support the use of Botox in certain more recently described regions such as the superolateral orbicularis oculi and the depressor anguli oris.
肉毒杆菌素的新应用和注射部位不断发展。本研究旨在分析各种注射部位的肉毒杆菌素治疗效果，以区分始终能产生令人印象深刻效果的治疗方法和那些效果较差的治疗方法。还评估了在两年期间，每个面部亚部位的肉毒杆菌素使用的流行率变化。
对在私人美容外科诊所接受肉毒杆菌素注射的 60 名患者进行了回顾性图表审查。患者样本取自相隔两年的 24 个月周期。收集的信息包括剂量和注射间隔及模式。分析的结果包括亚部位注射的流行率和保留率。
最常注射的亚部位是眉间区域。结果显示，接受外侧眼轮匝肌（57-80%）和口角降肌（10-20%）治疗的患者数量呈显著增加趋势。
肉毒杆菌素注射用于面部年轻化，患者满意度非常高。在测量期间，传统注射部位的治疗流行率非常稳定。研究结果支持在某些最近描述的区域使用肉毒杆菌素，如外侧眼轮匝肌和口角降肌。
