Abstract
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. Management of these patients has included bougienage and pharyngeal myotomy and/or pharyngeal neurectomy. 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.
