Assessment of chronic childhood dysphonia.

Chronic childhood dysphonia is a common condition in the school-age period. Perceived functional disorder is subjective and the alert is usually given by a person not belonging to the child's immediate environment. History-taking often suggests a malformation or acquired lesion. Functional assessment helps measure and diagnose the vocal impairment. Physical and endoscopic assessment in consultation is the key examination: it is only rarely impossible in children and can often found diagnosis. Additional examinations are sometimes necessary.
