You can not talk after such an operation, since everything that is normally used to produce speech, removed by surgery.
- Taleventil: Following the removal of the larynx inserts, in some cases a taleventil in an artificially created connection between the trachea and throat. This means that the patient will be able to learn to speak almost normally.
- Talepædagog: Many can learn to use a so-called esophagusstemme. Here is used air from the gullet (esophagus) and the stomach to speak.
