Description
Designed for individuals who have undergone a total laryngectomy, this voice prosthesis features a large esophageal flange to enhance speech restoration. Inserted into a surgically created tracheoesophageal puncture (TEP), it facilitates communication by allowing air from the lungs to pass into the esophagus through a one-way valve mechanism.
Key Features
-
Enhanced Sealing: The large esophageal flange provides improved sealing at the esophageal end, reducing leakage around the prosthesis. This is particularly beneficial for patients with enlarged or irregular puncture tracts.
-
Double Flange Option: Some models offer both large esophageal and tracheal flanges, providing a "double seal" for significantly enlarged or irregularly shaped punctures.
-
One-Way Valve: This mechanism allows air to pass from the trachea to the esophagus for speech, while preventing food, liquids, or saliva from entering the trachea.
-
Durable Construction: Made from biocompatible, medical-grade silicone, ensuring durability and patient safety.
Variants
Available in both indwelling and non-indwelling types, the prosthesis can be managed by healthcare professionals or the patients themselves. Some models include an anti-fungal additive, such as silver oxide, to inhibit Candida growth and reduce biofilm formation.
Design Benefits
-
Minimal Airflow Resistance: Designed to minimize resistance, reducing speaking effort and enhancing voice quality.
-
Size Variability: Offered in multiple sizes and lengths, commonly in diameters of 16 Fr and 20 Fr, and lengths ranging from 4 mm to 22 mm, to meet individual anatomical needs.
Maintenance
Compatible with various cleaning accessories, including flushing systems, brushes, and plug inserts, to maintain hygiene and manage temporary leakage. Regular cleaning is essential to prevent yeast and bacterial growth, which can affect the device's performance.
Lifespan
The lifespan of the device typically ranges from several weeks to several months, depending on factors such as diet, radiotherapy, and gastroesophageal reflux.
Intended Use
This prosthesis is intended for adult patients post-laryngectomy, particularly those experiencing periprosthetic leakage or with enlarged/irregular tracheoesophageal punctures. Proper sizing and a snug flange-to-flange fit are crucial for effectiveness, with some models offering increased valve resistance to prevent air ingestion and incremental lengths for precise fitting.
