Aphonia ( altgr. άφωνια < α " not " and φωνή "voice" ) refers to serious disruption in the formation of clay or loss of voice ( toneless language ). It is an organic distinguished from a functional or psychogenic cause.
In an organic -related functional impairment of the vocal folds is due to changes in the larynx (eg after surgery) or paralysis the function restricted so that only a lack of vocal tone can be generated.
Formerly called as psychogenic aphonia disorder ( current term: dissociative dysphonia ) has no organic basis. For this purpose, for example, an emotional cause or a neurotic conflict processing in charge ( with conversion hysterical symptom formation ).
The functional constraint is divided into two forms, each of which has different functional disturbances to the cause, and thus does not allow for normal voice production:
Therapeutically an organic aphonia is treated by eliminating the change in the phonosurgery with mostly complementary voice therapy, while a psychotherapeutic process for working the underlying disorder is parallel to voice therapy required in the dissociative dysphonia.
