In cervical dystonia, the accuracy of botulinum neurotoxin (BoNT) injections may influence the response to the treatment. We used ultrasound to evaluate the accuracy of anatomy-guided injections of BoNT in the neck muscles. A total of 56 consecutive patients and 332 injections were evaluated. The overall accuracy was 76.6%. The lowest accuracy (67.9%) was observed for the splenius capitis muscle. Anatomic guidance of BoNT injections in the neck muscles is often inaccurate. Imaging guidance may improve the accuracy of BoNT injections in cervical dystonia. © 2020 European Academy of Neurology.
