Hoarseness
Hoarseness, or dysphonia, is any change in the voice that makes it rough, breathy, strained, weak, or harder to use. It is a symptom rather than a diagnosis: the work is in finding its cause.
What it is
The voice is produced by the vocal folds vibrating as air passes between them. Anything that changes their shape, their flexibility, their movement, or how they close can change the voice. That is why hoarseness has many causes, from a passing cold to a lesion that needs treatment.
Common causes
- acute laryngitis, usually with a cold, which settles within two weeks
- benign vocal fold lesions: nodules, polyps and cysts
- muscle tension dysphonia, where the voice is produced with excess effort
- vocal fold paralysis or weakness, often after surgery on the neck or chest
- sulcus and scar, which stiffen the vibrating layer
- neurological conditions such as spasmodic dysphonia, tremor and Parkinson’s disease
- smoking-related change, including Reinke’s oedema and leukoplakia
- precancerous lesions and cancer of the larynx
When to seek assessment
A hoarse voice lasting more than three to four weeks should be examined, and sooner if you smoke, have had recent surgery on the neck or chest, or rely on your voice for work. Seek assessment promptly if hoarseness comes with difficulty breathing, pain, difficulty swallowing, coughing blood, or a lump in the neck.
How it is diagnosed
Diagnosis rests on looking at the vocal folds. Laryngoscopy shows their structure and movement; stroboscopy adds a slow-motion view of vibration, which reveals problems a standard examination can miss. Acoustic and perceptual measures document the voice so that change can be tracked.
Treatment
Treatment follows the cause. Many problems respond to voice therapy; some need an office-based procedure or surgery; a few need urgent tissue diagnosis. We explain the finding, the options, and what each can realistically change.

Frequently asked questions
How long is too long to be hoarse?
If hoarseness lasts more than three to four weeks without an obvious cause that is settling, the vocal folds should be examined. Professional voice users, smokers, and anyone with pain, breathing or swallowing difficulty, or a neck lump should be seen sooner.
Is hoarseness a sign of cancer?
Most hoarseness has a benign cause. Persistent hoarseness is, however, the commonest early sign of laryngeal cancer, which is why a hoarse voice that does not settle should be examined rather than watched indefinitely.
Can reflux cause hoarseness?
Reflux can irritate the larynx and is often suggested as a cause. It is also over-diagnosed. We look for other causes before attributing hoarseness to reflux, and we reassess if treatment for reflux does not help.
