Swallowing difficulties caused by a voice prosthesis in a laryngectomee.

INTRODUCTION

The role of voice prosthesis (VP) in causing swallowing difficulties has not been thoroughly evaluated. A laryngectomee with dysphasia caused by a VP is presented.

CASE REPORT

A 77-year-old laryngectomee presented with dysphagia. He had hypo pharyngeal squamous cell carcinoma, which was treated with intensity-modulated radiotherapy 13 years earlier. Cancer recurrence 2 years later required laryngectomy and forearm free flap restoration. The patient used trachea-oesophageal speech for communication using Provox® Vega 22.5/Fr 6mm. Diagnostic endoscopy revealed significant oesophageal stenosis at the upper portion of the flap immediately below the VP. The VP was replaced with a 22.5 Fr/4mm Provox® Vega that was modified by cutting out its distal hood that protruded into the oesophageal lumen. The patient noted an immediate improvement in his dysphagia that persisted through the 14-month follow-up.

CONCLUSIONS

This report underscores the need to evaluate the role of VP in laryngectomees with swallowing difficulties. Obstruction generated by oesophageal protrusion of the VP can be alleviated by installing a thinner prosthesis and/or when possible by changing the location of the puncture to a new site.
