A voice prosthesis (plural prostheses) is an artificial device, usually made of silicone that is used in conjunction with voice therapy to help laryngectomized patients to speak. During a total laryngectomy , the entire voice box ( larynx ) is removed and the windpipe ( trachea ) and food pipe ( esophagus ) are separated from each other.
Indications include voice rehabilitation for patients who are undergoing a total laryngectomy (primary puncture) or patients who have had a total laryngectomy in the past (secondary puncture). Contra-indications are mainly related to the use of the voice prosthesis and not the puncture procedure itself. It is important to have healthy tissue at ...
The voice prosthesis is a one-way air valve that allows air to pass from the lungs/trachea to the esophagus when the stoma is covered, where the redirected air vibrates the esophageal tissue to produce a hoarse voice. [26] The TEP and voice prosthesis combination allows individuals post-laryngectomy to have a voice to speak, while also avoiding ...
Increasing prevalence of laryngeal cancer worldwide drives demand for voice prosthesis devices for speech restoration post-laryngectomy. Continuous innovation enhances device functionality, durability, and patient comfort, driving market growth and adoption. Growing elderly population increases the need for voice prosthesis devices to address ...
After a total laryngectomy, the upper airways are bypassed and breathing in and out occurs through the tracheostoma in the neck which means that the inhaled air flows directly into the lungs. These anatomical changes lead, among others, to changes in voice production, breathing, and olfaction. The nasal functions of regulating the temperature ...
The voice Alexis “Lexi” Bogan had before last summer was exuberant. Then that voice was gone. When the breathing tube came out a month later, Bogan had trouble swallowing and strained to say ...

Along with developing esophageal voice, using a speech synthesizer, or undergoing a surgical procedure, the electrolarynx serves as a mode of speech recovery for laryngectomy patients. [2] [3] The Voice Quality Symbol for electrolaryngeal phonation in speech is И, approximating the symbol for electricity.
