Abstract：
The management of chronic migraine (CM) underwent a significant shift with the introduction of onabotulinumtoxin A (BoNT-A) injections following the landmark PREEMPT trial in 2010. Despite its efficacy, the existing injection protocol lacks precision, prompting a call for revision in light of modern ultrasound (US)-guided techniques. This article highlights the potential of US-guided injections to enhance accuracy, safety, and efficacy in CM treatment. By providing real-time visualization and addressing anatomical variations, US guidance offers a promising avenue for optimizing BoNT-A delivery, minimizing adverse effects, and ensuring therapeutic success.
摘要：
在2010年具有里程碑意义的PREEMPT试验之后，慢性偏头痛（CM）的管理发生了重大转变，即引入了单乳毒素A（BoNT-A）注射。尽管它的功效,现有的注射方案缺乏精确性，促使人们呼吁根据现代超声（US）引导技术进行修订。这篇文章强调了美国指导注射提高准确性的潜力，安全,在CM治疗中的疗效。通过提供实时可视化和解决解剖变化，美国指南为优化BoNT-A交付提供了一个有希望的途径，尽量减少不利影响，并确保治疗成功。
