# Approach to hoarseness

- Approach to a complaint

Hoarseness lasting more than 3 weeks, above all in a smoker, means the vocal folds must be seen to rule out laryngeal cancer.

## Key points

- Hoarseness for more than 3 weeks (NIDCD), above all without a preceding cold: the vocal folds must be seen.
- Smoker or drinker with persistent hoarseness: laryngoscopy to rule out laryngeal cancer.
- Glottic cancer causes early hoarseness, so it is usually found at an early stage (NCI).
- The true vocal folds have almost no lymphatics: glottic cancer confined to the fold rarely spreads to nodes.
- Breathy voice after thyroid or chest surgery: vocal fold paralysis from recurrent laryngeal nerve injury.
- Nodules: bilateral, from heavy voice use; a polyp: usually one-sided (NIDCD).

## What it is

Hoarseness (dysphonia) is a change in voice quality: rough, breathy, strained, weaker or lower in pitch. It almost always reflects a problem of the vocal folds. Most acute cases are due to viral laryngitis or voice overuse and get better within days. What drives the decision is duration, tobacco and alcohol use, and the symptoms that come with it. The NIDCD advises seeing a doctor if hoarseness lasts more than 3 weeks, especially without a preceding cold; glottic cancer causes early hoarseness, so persistent hoarseness in a smoker is investigated with laryngoscopy, not with trial treatments.

## Key questions in the history

- Since when? Did it start with a cold or is it persistent?
- Does the patient smoke or drink alcohol? For how long and how much?
- Heavy voice use (teacher, singer, vendor) or shouting before it started?
- Pain on swallowing, dysphagia, earache, coughing blood, a neck lump or breathing difficulty?
- Recent thyroid, neck or chest surgery, or intubation?
- Heartburn, constant throat clearing or a voice worse in the morning (reflux)?

## Causes and classification

- Inflammatory: acute viral laryngitis (the commonest) and laryngopharyngeal reflux laryngitis.
- Voice use: nodules, polyps, cysts and vocal fold haemorrhage.
- Neurological: vocal fold paralysis, Parkinson disease, stroke and spasmodic dysphonia.
- Neoplastic: laryngeal cancer and recurrent respiratory papillomatosis (HPV 6 and 11).
- Other: thyroid problems and laryngeal trauma.

## Step-by-step approach

- Assess breathing first: hoarseness with stridor or breathing difficulty is an emergency.
- Establish the duration: acute hoarseness after a cold usually settles with voice rest and fluids.
- Ask about tobacco, alcohol, voice use, neck or chest surgery and intubation.
- Examine the mouth and oropharynx and palpate the neck: lymph nodes and thyroid.
- If it lasts more than 3 weeks, or sooner if there are red flags, refer to have the vocal folds seen.
- The ENT surgeon uses a flexible endoscope or a mirror and may add special voice tests.
- If there is a suspicious lesion: biopsy and staging (CT, MRI or PET-CT) before treatment.
- Vocal fold paralysis with no obvious cause: image the course of the recurrent laryngeal nerve.

## Common causes of hoarseness

| Cause | Clues | What to do |
| --- | --- | --- |
| [Acute laryngitis](https://durgical.com/en/conditions/vocal-fold-nodules-polyps-and-laryngitis/) | After a cold or respiratory infection; lasts days | Voice rest and fluids; review if it lasts beyond 3 weeks |
| [Nodules and polyps](https://durgical.com/en/conditions/vocal-fold-nodules-polyps-and-laryngitis/) | Heavy voice use; nodules bilateral, polyp one-sided | Voice therapy; surgery if no improvement |
| [Laryngopharyngeal reflux](https://durgical.com/en/conditions/gastro-oesophageal-reflux-disease/) | Constant throat clearing, voice worse in the morning, heartburn may be absent | Diet changes and acid-reducing drugs |
| [Vocal fold paralysis](https://durgical.com/en/conditions/vocal-fold-paralysis/) | Breathy voice, coughing when drinking; previous thyroid or chest surgery | Laryngoscopy and imaging of the nerve's course |
| [Laryngeal cancer](https://durgical.com/en/conditions/laryngeal-cancer/) | Smoker or drinker, progressive hoarseness | Priority referral for laryngoscopy and biopsy |
| Recurrent respiratory papillomatosis | Child or adult; HPV 6 and 11; may block the airway | Referral to ENT; repeated surgery |

## Red flags

- Hoarseness for more than 3 weeks without a clear cause.
- Smoking or alcohol use with persistent hoarseness.
- Coughing blood, dysphagia, painful swallowing or referred earache.
- A neck lump.
- Stridor or breathing difficulty.
- Complete loss of voice for more than a few days.

## Next step / Initial management

- Acute hoarseness without red flags: voice rest, fluids, avoid tobacco and irritants; review if not better within 3 weeks.
- Suspected reflux: diet changes and acid-reducing drugs (proton pump inhibitors), without delaying laryngoscopy if hoarseness persists.
- Nodules or voice misuse: voice therapy with a speech-language therapist.
- Refer to ENT for laryngoscopy if it lasts more than 3 weeks; the referral is a priority (within days) in smokers or drinkers and when there is a neck lump, coughing blood or dysphagia.
- Stridor or breathing difficulty: urgent referral, the same day, to the emergency department.
- Hoarseness after thyroid or neck surgery: early ENT referral.

## Test yourself

Think of the answer, then tap the question to see it.

## A 62-year-old smoker has been hoarse for 5 weeks with no preceding cold. What is the next step?

Priority referral to ENT for laryngoscopy: hoarseness for more than 3 weeks in a smoker must be investigated for laryngeal cancer; do not treat blindly.

## Why is glottic cancer usually found early and why does it rarely spread to lymph nodes?

Because hoarseness appears early and the true vocal folds have almost no lymphatics.

## A patient has had a breathy voice since a thyroidectomy. Which nerve was probably injured?

The recurrent laryngeal nerve, which supplies almost all intrinsic laryngeal muscles; its injury paralyses the vocal fold.

## Which viruses cause recurrent respiratory papillomatosis and what is its commonest symptom?

HPV types 6 and 11; hoarseness is the commonest symptom and the papillomas can eventually block the airway.
