Voice prosthesis

Voice Prosthesis is a medical device that is used to help patients speak after they have had a laryngectomy, a surgical procedure to remove the larynx or voice box. This device is usually made of silicone and is placed in a surgically created hole between the trachea and the esophagus.

Types of Voice Prosthesis

There are two main types of voice prosthesis: indwelling and non-indwelling.

• Indwelling Voice Prosthesis - This type of prosthesis is inserted and removed by a healthcare professional. It is typically used for patients who have difficulty inserting the prosthesis themselves.

• Non-Indwelling Voice Prosthesis - This type of prosthesis can be inserted and removed by the patient or a caregiver. It gives the patient more control over their device.

How a Voice Prosthesis Works

A voice prosthesis works by directing air from the lungs into the esophagus, where it is then expelled through the mouth. This air movement vibrates the walls of the esophagus, creating sound. The patient can then form this sound into speech by moving their mouth and tongue.

Care and Maintenance

Proper care and maintenance of a voice prosthesis is essential to ensure its longevity and effectiveness. This includes regular cleaning to prevent the buildup of bacteria and yeast, which can cause the prosthesis to malfunction. It is also important to monitor the prosthesis for signs of wear and tear, as it may need to be replaced every few months.

Risks and Complications

While a voice prosthesis can greatly improve a patient's quality of life after a laryngectomy, there are some risks and complications associated with its use. These can include infection, dislodgement of the prosthesis, and difficulty speaking clearly. It is important for patients to discuss these risks with their healthcare provider before deciding to use a voice prosthesis.
