Hoarse voice that won't go away, when to actually worry

There's a useful rule in ENT: any hoarse voice that lasts more than two to three weeks deserves a proper examination of the vocal cords, especially in smokers, especially after age 40. Most hoarseness is from harmless overuse or a chesty cold. A small percentage isn't, and the difference matters enormously when caught early.

Common causes, usually fixable

• Acute laryngitis from a recent cold or chest infection, settles in days
• Voice strain in teachers, lawyers, religious singers, call-centre staff
• Vocal cord nodules from years of strain, 'singer's nodes'
• Vocal cord polyps from a single intense voice abuse episode
• Acid reflux laryngitis (LPR), silent reflux burning the vocal cords
• Allergic post-nasal drip irritating the larynx

Causes that need urgent investigation

• Vocal cord paralysis (one cord not moving)
• Pre-malignant changes (leukoplakia) on the vocal cords
• Early laryngeal cancer, highly curable when caught early
• Tumours pressing on the recurrent laryngeal nerve (eg from thyroid)

Why a proper exam matters more than guessing

From the outside, all these causes look identical, a hoarse voice and a normal-looking throat on tongue depression. The vocal cords sit deep in the throat and are not visible without a flexible endoscope. A 5-minute outpatient endoscopy gives a clear answer in nearly every case.

How the exam is done

A small spray of local anaesthetic numbs the nostril, then a thin flexible endoscope passes through the nose and looks down at the vocal cords moving in real time. It's barely uncomfortable, takes a few minutes, and gives you a definitive answer the same visit. In specific cases we use a stroboscope which captures vocal cord vibration in slow motion, useful for subtle nodules and polyps.

What treatment looks like

• Acute laryngitis: voice rest, warm fluids, treating the underlying infection
• Reflux laryngitis: PPI medication and dietary changes, often dramatically helpful
• Vocal cord nodules: voice rest plus structured voice therapy with a speech therapist
• Polyps that don't shrink with rest: a brief micro-laryngeal day-care surgery
• Pre-malignant changes: biopsy and close follow-up
• Early cancer: highly curable with appropriate treatment when caught early

The single most important sentence

If you're a smoker over 40 and your voice has been hoarse for more than two weeks, please get a vocal cord examination this week. Not next month. Most of the time it will be nothing serious. The few times it isn't, early diagnosis literally changes the outcome.
