Cricopharyngeal Botulinum Toxin Injection under Ultrasonic Guidance for Dysphagia from Wallenberg's Syndrome: A Case Report / 中国康复理论与实践

ABSTRACT

Objective:To investigate the effect of cricopharyngeal injection of Botulinum toxin under ultrasonic guidance for treatment of dysphagia caused by Wallenberg's syndrome. Methods:A case was reviewed. Results:This patient was diagnosed as cricopharyngeal achalasia after dorsal lateral rostral infarction, and responded poor to routine treatment for swallowing disorders, including balloon dilatation. He accepted cricopharyngeal Botulinum toxin injection under ultrasonic guidance. As evaluated with Toshima Ichiro Ingestion-Swallowing Function Rating Scale, Rosenbek Penetration-Aspiration Scale and videofluoroscopic swallowing study (VFSS), his swallowing improved after treatment, and became normal as follow-up one and three months after treatment. Conclusion:Cricopharyngeal Botulinum toxin injection under ultrasonic guidance is feasible for cricopharyngeal achalasia of Wallenberg's syndrome with immediate and long-term effect.
