Why persistent hoarseness must be examined
Voice changes are usually caused by something benign — a viral infection, voice overuse, reflux irritation, or a nodule from vocal strain. But the vocal cords are also where laryngeal cancer begins, and hoarseness is frequently its earliest symptom, at a stage when treatment is highly successful.
The rule used internationally is simple: hoarseness that lasts more than three weeks should be investigated by looking at the vocal cords. Not treated blindly with repeated antibiotics or steam. Looking is quick, done in the clinic, and settles the question.
Symptoms worth assessing
- Hoarseness or voice change persisting beyond three weeks
- Voice that tires or fades through the day, particularly in teachers, singers and those who speak for a living
- Frequent throat clearing, a lump-in-the-throat sensation, excess mucus
- Pain on speaking or swallowing
- Difficulty swallowing solids, food sticking, coughing while eating
- Unexplained weight loss, blood in phlegm, or a neck lump — these need prompt assessment
Common causes
Vocal cord nodules and polyps
Caused by repeated vocal strain, typically in teachers, singers, sales professionals and anyone who raises their voice habitually. Nodules usually respond to voice therapy and technique correction; polyps often need a minor endoscopic procedure followed by therapy to prevent recurrence.
Laryngopharyngeal reflux (throat reflux)
Acid reaching the throat irritates the voice box, causing hoarseness, throat clearing, a lump sensation and cough — frequently without any heartburn at all, which is why it is often missed. Treated with dietary and lifestyle change alongside medication where appropriate.
Voice misuse and muscle tension
The larynx can be structurally normal while the voice is produced with excessive tension. Voice therapy is the treatment, and it is genuinely effective.
Vocal cord paralysis
Weakness of a vocal cord causes a breathy, weak voice and sometimes coughing on drinking. It requires investigation of the nerve pathway, as the cause may lie in the neck or chest.
Swallowing difficulty
Causes range from reflux and muscle incoordination to neurological conditions and structural narrowing. Difficulty swallowing solids that is progressive, especially with weight loss, always requires prompt evaluation.

Open the questionnaire →How the larynx is examined
Examination is done in the clinic with a flexible laryngoscope — a fine flexible telescope passed through the nose after local anaesthetic spray. It takes a couple of minutes, requires no sedation, and shows the vocal cords moving in real time as you speak and swallow.
Where a more detailed view is needed, stroboscopy uses a flashing light source to visualise the wave-like vibration of the vocal cord surface, revealing subtle abnormalities that ordinary examination cannot show.
Additional assessment may include a validated symptom score (the Reflux Symptom Index for throat reflux, EAT-10 for swallowing), a swallowing study, and imaging where indicated.
Treatment
- Voice therapy — the mainstay for nodules, muscle tension and voice misuse, and essential after most voice surgery. Working with a speech and language therapist changes how the voice is produced rather than just treating the result
- Reflux management — dietary modification, avoiding late meals, weight and lifestyle measures, with medication where warranted
- Microlaryngeal surgery — precise endoscopic removal of polyps, cysts and other lesions through the mouth under general anaesthesia, with no external cuts, followed by voice rest and therapy
- Treating the underlying cause — allergy, chronic cough, thyroid disease or neurological conditions where these are contributing
Hoarseness persisting beyond three weeks, progressive difficulty swallowing solids, unexplained weight loss, blood in the phlegm, persistent one-sided throat or ear pain, a lump in the neck, or noisy breathing. These do not necessarily mean anything sinister, but they should be looked at without delay rather than treated blindly.

Frequently asked questions
How long should hoarseness last before I see a doctor?
Hoarseness persisting beyond three weeks should always be assessed by examining the vocal cords, regardless of how well you otherwise feel. Most causes are benign and treatable, but this rule exists because early laryngeal cancer commonly presents as hoarseness alone at a stage when treatment is highly successful.
Is laryngoscopy painful?
No. Flexible laryngoscopy is done in the clinic with a fine flexible telescope passed through the nose after a local anaesthetic spray. It takes about two minutes, needs no sedation, and most patients find it uncomfortable for a few seconds rather than painful. You can drive home and return to work immediately.
What causes vocal cord nodules and how are they treated?
Nodules result from repeated vocal strain and are common in teachers, singers and others who use their voice heavily. Most respond to voice therapy that corrects how the voice is produced, along with treatment of contributing factors like reflux. Surgery is reserved for lesions that do not settle with therapy, and voice therapy is still needed afterwards to prevent recurrence.
Can I have throat reflux without heartburn?
Yes, and it is common. Laryngopharyngeal reflux irritates the throat and voice box causing hoarseness, frequent throat clearing, a lump-in-the-throat sensation and cough, often with no heartburn at all. This is why it is frequently missed and treated as an infection instead.
When is difficulty swallowing serious?
Difficulty swallowing solids that is progressive, particularly with unexplained weight loss, food sticking, pain on swallowing, or blood in the phlegm, requires prompt evaluation. Occasional difficulty with tablets or a lump sensation without these features is usually less concerning but still worth assessing if it persists.
Will surgery on my vocal cords change my voice?
Microlaryngeal surgery aims to restore normal voice by precisely removing the lesion while preserving the delicate vibrating layer of the vocal cord. Results are generally good, but voice rest and voice therapy afterwards are an essential part of the outcome, and the underlying vocal habits must be addressed or the problem can return.
