A closer look at vocal fold insufficiency as a cause of dysphonia

Dysphonia is difficulty in phonation. It is often referred to as hoarseness. The characteristics of dysphonia include altered vocal quality, pitch, loudness, or effort needed to speak. Dysphonia makes communication difficult, which may reduce quality of life for many patients.1

Vocal fold insufficiency (glottic insufficiency) is a frequent underlying cause of dysphonia.2 Vocal fold insufficiency is often overlooked as a cause, however, and this underrecognition may prevent some patients from getting appropriate treatment for their vocal fold insufficiency. In addition, some older adults simply consider dysphonia a natural part of aging and, therefore, may not seek medical advice.1

Not an actual patient.
