Substitute voice (medicine)
A substitute voice (sometimes also: "Ruktus voice" ) is a voice production after total laryngectomy , in which, after appropriate medical rehabilitation, folds of the mucous membrane at the level of the esophageal mouth are vibrated by expelling air ( similar to belching ).
The traditional esophageal voice is one of three communication options (traditional esophageal voice, shunt valve voice and electronic speaking aid). It is learned as part of voice rehabilitation . To what extent and whether the person concerned can learn this variant of the substitute voice depends on various individual factors such as B. extent of the operation, medical pre-treatment and / or follow-up treatment (radiation, chemotherapy), physical and psychological resilience and age. On average, it takes several months to a year for the larynx to develop a fluent, easily understandable voice.
