title: Voice change in the pediatric patient. A differential diagnosis.
abstract: This paper reviews the causes of voice change in the infant and child. Symptoms of dysphonia can be very early evidence of a serious problem, either within the larynx or resulting from a systemic disease. The need to investigate the cause of voice disturbances is stressed. The large number of diseases in which voice change occurs makes a complete examination of the child, both local and systemic, absolutely necessary in order to arrive at a specific diagnosis. The mechanism of voice change is described in each category of the numerous causes of dysphonia.
