Abstract

Introduction: Ultrasonography (US) has become an essential tool for guiding botulinum neurotoxin (BoNT) injections in facial muscles, enhancing precision and safety. This narrative review explores the role of US in BoNT administration, particularly in complex anatomical regions, highlighting its impact on treatment customization, real-time visualization, and complication reduction.

Materials and methods: A comprehensive literature search was conducted using PubMed, MEDLINE, Embase, and Cochrane Library for articles published from January 2018 to December 2023. Search terms included "Botulinum neurotoxin," "facial anatomy," "ultrasonography guided injection," and "facial muscle sonoanatomy." Studies focusing on US-guided BoNT injections in facial muscles were included. Data extraction and synthesis were performed independently by two reviewers, focusing on study design, ultrasonography techniques, outcomes, and conclusions.

Results: The review found that US guidance significantly enhances the precision of BoNT injections by providing real-time visualization of facial muscles and blood vessels, thereby reducing the risk of adverse events. US enables tailored injection strategies, ensuring symmetrical facial expressions and minimizing over-treatment. The technique also offers immediate feedback, allowing for on-the-spot adjustments to improve treatment efficacy and safety. However, the review identified limitations, including potential selection bias and variability in US techniques across different studies.

Conclusion: US guidance for BoNT injections into facial muscles offers substantial benefits in terms of precision, safety, and treatment customization. Despite the identified limitations, the integration of US into clinical practice is poised to enhance patient outcomes in aesthetic and therapeutic procedures. Further research is needed to standardize US techniques and broaden the inclusivity of studies to validate these findings comprehensively.

向面部肌肉注射肉毒杆菌神经毒素的声纳解剖学。

简介超声波成像（US）已成为引导面部肌肉注射肉毒杆菌神经毒素（BoNT）的重要工具，可提高注射的精确性和安全性。这篇叙述性综述探讨了 US 在 BoNT 注射中的作用，尤其是在复杂的解剖区域，强调了其对治疗定制、实时可视化和减少并发症的影响：使用 PubMed、MEDLINE、Embase 和 Cochrane Library 对 2018 年 1 月至 2023 年 12 月期间发表的文章进行了全面的文献检索。检索词包括 "肉毒杆菌神经毒素"、"面部解剖"、"超声引导注射 "和 "面部肌肉声纳解剖"。纳入的研究侧重于 US 引导下的面部肌肉 BoNT 注射。数据提取和综合由两名审稿人独立完成，重点关注研究设计、超声技术、结果和结论：综述发现，超声引导可实时观察面部肌肉和血管的情况，从而大大提高了 BoNT 注射的精确性，降低了不良事件的风险。US 可实现量身定制的注射策略，确保面部表情对称，最大限度地减少过度治疗。该技术还能提供即时反馈，允许进行现场调整，以提高治疗效果和安全性。不过，综述也发现了一些局限性，包括潜在的选择偏差和不同研究中 US 技术的差异：结论：用 US 引导向面部肌肉注射 BoNT，在精确性、安全性和治疗定制化方面具有很大优势。尽管存在已发现的局限性，但将 US 技术融入临床实践有望提高患者在美容和治疗过程中的疗效。还需要进一步的研究来规范 US 技术并扩大研究的包容性，以全面验证这些发现。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
