Textbook-Ultrasound-Cadaver: A Three-Step Learning Method in Facial Botulinum Toxin Type A Injection.

[BACKGROUND] Facial botulinum toxin type A injections are among the most common procedures in the field of aesthetic surgery. However, this procedure requires practitioners to have a comprehensive understanding of the anatomical distribution of facial muscles.

[OBJECTIVES] To aid young physicians in mastering facial botulinum toxin injections methodically, a three-step learning approach that integrates anatomical atlases, ultrasound imaging, and cadaver dissection-termed the Textbook-Ultrasound-Cadaver method-was implemented.

[METHODS] Over a 1-year period, four training sessions were conducted, involving 115 young clinicians. The training combined didactic lectures on facial anatomy, hands-on ultrasound examinations, and cadaver dissection with injection simulation. Participants rated their understanding of facial muscle anatomy before and after the training, as well as their overall satisfaction with the course.

[RESULTS] Participants' self-rated understanding of facial anatomy increased from 6.5 ± 2.7 to 8.9 ± 1.8 points after the training. Course satisfaction was high at 9.2 ± 2.1 points.

[CONCLUSIONS] The Textbook-Ultrasound-Cadaver method provides a structured approach to learning facial botulinum toxin injections, integrating key anatomical knowledge with practical imaging and hands-on training.
