Voice failure after tracheoesophageal puncture: management with botulinum toxin.
Primary or secondary tracheoesophageal puncture with a speaking prosthesis has provided rehabilitation of speech in most patients after total laryngectomy. Persistent constrictor spasm is thought to be responsible for a small percentage of these patients' inability to speak with the prosthesis. ⋯ Botulinum toxin injections of the cricopharyngeus muscle complex in six patients have been successfully used diagnostically and therapeutically for tracheoesophageal puncture failures. The assessment, technique, and results are discussed.
