Ultrasound-guided Botulinum Toxin Injection on Cricopharyngeal Muscle Dysfunction

Summary

Ultrasound-guided injection is a visual, convenient, and radiation-free technique that allows real-time observation of the needle insertion process and drug injection location. The combination with a balloon for fixation further enhances the precision of the injection. In this study, the investigators employed ultrasound-guided injection combined with balloon localization for cricopharyngeal muscle botulinum toxin injection treatment and conducted clinical observations.
