An overview of voice prosthesis used in medical treatments

Voice Prosthesis[edit]

A voice prosthesis is a medical device used to help individuals who have lost their natural voice due to a laryngectomy or other medical conditions. This device is typically used by patients who have undergone surgery for laryngeal cancer and have had their larynx removed, resulting in the loss of normal voice production.

Function[edit]

The primary function of a voice prosthesis is to enable tracheoesophageal speech, which is a method of voice restoration. After a laryngectomy, a surgical procedure creates a small opening between the trachea and the esophagus, known as a tracheoesophageal puncture (TEP). The voice prosthesis is inserted into this puncture to allow air from the lungs to pass into the esophagus, where it vibrates the esophageal tissues to produce sound.

Types of Voice Prostheses[edit]

There are several types of voice prostheses, each designed to meet specific needs of patients:

Indwelling Prostheses: These are designed to be long-lasting and are typically replaced by a healthcare professional.
Non-indwelling Prostheses: These can be removed and cleaned by the patient themselves, offering more independence.

Insertion and Maintenance[edit]

The insertion of a voice prosthesis is a relatively simple procedure that can be performed in a clinical setting. Maintenance of the device is crucial to prevent complications such as infection or blockage. Regular cleaning and periodic replacement are necessary to ensure optimal function.

Advantages and Limitations[edit]

Voice prostheses offer several advantages, including the ability to produce a more natural-sounding voice compared to other methods such as electrolarynx or esophageal speech. However, they also have limitations, such as the need for regular maintenance and the potential for device-related complications.

-==How a Voice Prosthesis Works==
+=== Types of Voice Prostheses ===
-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.
+There are several types of voice prostheses, each designed to meet specific needs of patients:
-==Care and Maintenance==
+* '''Indwelling Prostheses''': These are designed to be long-lasting and are typically replaced by a healthcare professional.
-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.
+* '''Non-indwelling Prostheses''': These can be removed and cleaned by the patient themselves, offering more independence.
-==Risks and Complications==
+=== Insertion and Maintenance ===
-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.
