Description

The Blom-Singer Duckbill Voice Prosthesis is a specialized tracheoesophageal device designed to restore speech for individuals who have undergone a total laryngectomy. This innovative prosthesis facilitates communication by allowing pulmonary air to pass from the trachea to the esophagus, enabling sound production while preventing the aspiration of food, liquids, and saliva.

Key Features

• One-Way Valve Mechanism: The duckbill design ensures seamless airflow for speech while safeguarding the airway during swallowing.
• Patient-Changeable Design: This non-indwelling device can be independently inserted, removed, and maintained by the patient, enhancing convenience and autonomy.
• Non-Flanged with Safety Strap: Equipped with a safety strap and optional medallion to prevent accidental loss, providing peace of mind.

Specifications

• Available Lengths: Multiple lengths ranging from 6mm to 25mm to accommodate individual needs.
• Standard Diameter: Typically 16 French, with some variations up to 22.5 French.
• Material: Constructed from medical-grade silicone, ensuring durability and biocompatibility.

Functionality

The prosthesis is inserted into a surgically created tracheoesophageal puncture, where it operates under positive pressure during exhalation. This action opens the valve for speech and closes it to prevent aspiration. Users may occlude the stoma manually or use hands-free valves for automatic closure.

Maintenance

Regular cleaning is essential to prevent leakage and maintain optimal performance. The device should be checked daily for any signs of leakage or changes in voice quality. If issues persist, replacement may be necessary. The lifespan of the device varies, influenced by factors such as diet, radiotherapy, and reflux.

Common Challenges

• Leakage: May require cleaning or replacement.
• Accidental Removal: Mitigated by the safety strap.
• Voice Quality: Affected by pulmonary support and device condition.

Historical Significance

Introduced in 1980, the Blom-Singer Duckbill was the first commercially available voice prosthesis of its kind, marking a significant advancement in voice rehabilitation technology. Suitable for patients of all ages who can manage device care, it continues to enhance communication and quality of life for laryngectomy patients worldwide.
