Management of pharyngoesophageal spasm with Botox

Siew-Shuen Chao et al. Otolaryngol Clin North Am. 2004 Jun.

Abstract

Pharyngoesophageal spasm following laryngectomy can result in failure of tracheoesophageal (TE) speech and dysphagia. Chemical denervation with Clostridium botulinum toxin (Botox) is effective in relieving pharyngeal constrictor spasm, thereby facilitating TE speech production. This article reviews the technique, results,and complications regarding the use of Botox in the management of TE speech failure associated with pharyngoesophageal spasm.
