A hoarse voice after a cold or a loud evening is ordinary and settles within days. Hoarseness that persists for weeks is a different matter and is one of the symptoms most consistently ignored.
The rule is simple and worth knowing: any voice change lasting more than three weeks needs the vocal cords examined.
How the Voice Is Produced
The vocal cords are two bands of tissue in the larynx that vibrate as air passes between them. Pitch and quality depend on their tension, mass and how completely they close.
Anything that changes the mass of the cords, prevents them closing fully, or affects the nerves controlling them, changes the voice. That includes swelling, growths, paralysis and scarring.
Because the changes are mechanical, examining the cords directly usually gives the answer quickly.
The Common Causes
Most hoarseness has a benign explanation.
- Acute laryngitis: viral, settling within one to two weeks
- Voice overuse: teachers, singers, vendors, call centre staff and anyone who shouts regularly
- Vocal nodules: from chronic misuse, often described as singer nodules
- Vocal polyps or cysts
- Laryngopharyngeal reflux: stomach acid irritating the larynx, frequently without heartburn
- Smoking, causing chronic swelling and thickening
- Allergy and post nasal drip
- Hypothyroidism, which causes a deep hoarse voice
- Inhaled steroids for asthma, if the mouth is not rinsed after use
- Vocal cord paralysis, from nerve injury after thyroid or chest surgery
Reflux affecting the throat deserves attention because most patients have no heartburn at all, and the symptoms are throat clearing, a lump sensation, chronic cough and morning hoarseness.
The Three Week Rule
Persistent hoarseness is the most common early symptom of laryngeal cancer, and laryngeal cancer is highly curable when caught early.
Any hoarseness lasting more than three weeks warrants examination of the vocal cords, particularly in a smoker or someone who consumes alcohol regularly. The threshold should be lower still in someone over fifty with a smoking history.
The examination is laryngoscopy, done in the outpatient clinic with a flexible scope passed through the nose after local anaesthetic spray. It takes a few minutes and is uncomfortable rather than painful.
Most examinations find something benign, and that reassurance is worth the few minutes of discomfort.
Symptoms That Increase Concern
Hoarseness alongside any of these warrants prompt rather than routine assessment.
- A lump in the neck
- Difficulty or pain on swallowing
- Persistent ear pain with a normal ear examination, which can be referred from the throat
- Coughing up blood
- Unexplained weight loss
- Noisy breathing or breathlessness
- A history of smoking or heavy alcohol use
- Hoarseness worsening rather than fluctuating
Referred ear pain with a normal ear is a classically overlooked sign. The nerve supply to the throat and ear overlap, so throat pathology can present as earache.
Reflux Affecting the Throat
Laryngopharyngeal reflux differs from typical GERD in that acid reaches the throat, where the tissue is far more sensitive and has no protection.
- Chronic throat clearing
- A sensation of a lump in the throat
- Hoarseness, typically worst in the morning
- Chronic cough
- Excess throat mucus
- Usually no heartburn at all
Management involves not eating within three hours of lying down, raising the head of the bed, weight reduction, avoiding trigger foods, and acid suppression for a trial period. Improvement takes longer than for typical reflux, often two to three months, which is why patients frequently stop treatment too early. Our gastroenterology and ENT teams manage this together.
Looking After Your Voice
For people whose work depends on their voice, these measures prevent most problems.
- Stay well hydrated, since vocal cords need moisture to vibrate efficiently
- Avoid shouting and speaking over background noise. Use amplification if you teach or present regularly
- Do not whisper when hoarse, which strains the cords more than speaking softly
- Rest the voice completely during acute laryngitis rather than pushing through
- Avoid throat clearing, which traumatises the cords. Sip water or swallow instead
- Stop smoking, which is the single most important measure
- Limit caffeine and alcohol, both of which are drying
- Rinse the mouth after using inhaled steroids
Throat clearing is a habit that perpetuates itself. The clearing irritates the cords, which produces more mucus sensation, prompting more clearing.
Voice Therapy Works
For nodules, muscle tension problems and voice misuse, speech and voice therapy is often more effective than surgery and should generally come first.
Therapy addresses breathing support, resonance, pitch and the behaviours causing the damage. Vocal nodules in particular usually resolve with therapy alone, and operating without addressing the underlying technique means they recur.
Surgery has a role for polyps, cysts and lesions requiring biopsy, and microsurgery on the cords is precise and generally preserves voice quality well when done for the right indication.
Throat Symptoms That Are Not Hoarseness
Several other throat complaints come up frequently.
Globus sensation, a feeling of a lump without difficulty swallowing, is common and usually related to reflux or muscle tension. The key distinction is that food passes normally. If food actually sticks, that is a different symptom requiring investigation.
Chronic sore throat without infection is often reflux, allergy, mouth breathing or smoking related.
Tonsil stones, small white lumps causing bad breath, are harmless and usually managed with gargling and hydration.
Difficulty swallowing that is progressive, or where solids stick more than liquids, always needs investigation.
Hoarseness lasting more than three weeks needs the vocal cords looked at, particularly in smokers. The examination is quick, most findings are benign, and the conditions that are not are far more treatable when found early.
