Customized valve housing

Area of Science:

• Medical Engineering
• Otolaryngology
• Speech-Language Pathology

Background:

• Voice prosthetics offer remarkable advancements for patients with laryngeal conditions.
• Air leaks around tracheostome housings remain a significant challenge, especially for patients with irregular or recessed stomas.
• Maintaining an airtight seal is crucial for effective voice restoration and patient comfort.

Purpose of the Study:

• To describe a novel, customized tracheostome valve housing designed to address air leak issues.
• To evaluate the efficacy of this customized housing in maintaining an airtight seal.
• To assess the functional benefits and patient experience with the new device.

Main Methods:

• Fabrication of patient-specific tracheostome valve housings.
• Clinical evaluation involving 12 patients with voice prosthetics.
• Assessment of seal integrity and duration.

Main Results:

• The customized housings successfully minimized or alleviated air leaks.
• Patients maintained adequate airtight seals for a minimum of 72 hours.
• Patients reported functional benefits and improved usability of their voice prosthetics.

Conclusions:

• Customized tracheostome valve housings represent a significant improvement over standard devices.
• This approach effectively resolves persistent air leak problems in voice prosthetic users.
• The fabricated housings enhance the functional outcomes and quality of life for patients requiring voice restoration.
