Abstract
Total laryngectomy patients, after undergoing a tracheoesophageal puncture (TEP), may have poor TEP speech because of hypertonicity or spasm of the pharyngoesophageal segment (PES). Conventional treatment options include speech therapy, PES dilation, pharyngeal neurectomy, and myotomy. Botulinum toxin injection into the PES has recently been reported to be effective for this disorder. However, data accumulated were based primarily on subjective analyses. This prospective investigation used both qualitative and quantitative measures to assess the effects of videofluoroscopy-guided botulinum toxin injection on TEP voice quality in laryngectomees with PES dysfunction. Patients underwent voice analyses, tracheal air pressure measures, and barium swallows before and after botulinum toxin injection. Seven of 8 patients had significant voice quality improvement, and tracheal air pressures normalized in 6 of 8 patients after injection. Videofluoroscopic botulinum toxin injection into the PES is efficacious, safe, and cost-effective and should be considered as a first-line therapy for the treatment of laryngectomees with poor quality TEP speech caused by PES dysfunction.
