Blom-Singer® Laryngectomy Tubes are durable, lightweight silicone tubes that are used to keep the tracheostoma open after laryngectomy. They are available in a variety of sizes/styles and contours to the postoperative tracheal anatomy. For use with a voice prothesis, the recessed area may be modified (fenestrated) by a trained clinician for use with a Blom-Singer voice prothesis. However, for convenience a pre-fenestrated series is available that eliminates the need for manual fenestration. Blom-Sing Laryngectomy Tubes are available in three product offerings described below.
