Dysphonia Plica Ventricularis (Ventricular Dysphonia)

Here voice is produced by ventricular folds (false cords)
which have taken over the function of true cords. Voice
is rough, low-pitched and unpleasant. Ventricular voice
may be secondary to impaired function of the true cord
such as paralysiS, fixation, surgical excision, or tumours.
Ventricular bands in these situations try to compensate
or assume phonatory function of true cords.
Functional type of ventricular dysphonia occurs in
normal larynx . Here cause is psychogenic. In this type,
voice begins normally but soon becomes rough when
false cords usurp the function of true cords. Diagnosis is
made on indirect laryngoscopy; the false cords are seen to
approximate partially or completely and obscure the
view of true cords on phonation. Ventricular dysphonia
secondary to laryngeal disorders is difficult to treat but
the function al type can be helped through voice therapy
and psychological counselling.
