Hoarseness and Voice Change: Causes, Red Flags and When to See an ENT
Hoarseness — a change in voice quality, pitch, loudness or endurance — is one of the most common ENT complaints. It can range from a mild roughness after a cold to a complete loss of voice that derails professional and personal life. What most people don’t know is that the cause determines the treatment entirely, and that hoarseness lasting more than three weeks always warrants a formal evaluation.
How the Voice Works
Voice is produced when air from the lungs passes through the larynx and causes the two vocal cords (vocal folds) to vibrate. The frequency, tension and contact pattern of vibration determines pitch, tone and quality. Any condition that alters the mass, tension, closure or vibration of the vocal cords changes the voice.
The Most Common Causes
Acute Laryngitis
The most common cause of sudden hoarseness — typically viral, following an upper respiratory infection. The vocal cords become swollen and inflamed, altering their vibratory pattern. Management is voice rest, hydration and steam inhalation. Most acute laryngitis resolves within 1–2 weeks. Antibiotics are not indicated for viral laryngitis.
Vocal Cord Nodules
Small, callus-like growths that develop at the midpoint of the vocal cords — the point of maximum vibratory stress — from chronic vocal overuse or misuse. Common in teachers, singers, call centre workers and anyone who uses their voice extensively. Nodules cause a rough, breathy, effortful voice that worsens through the day. First-line treatment is voice therapy (vocal hygiene and retraining with a speech therapist). Microlaryngoscopy (surgical removal) is reserved for nodules that fail to respond to therapy.
Vocal Cord Polyps and Cysts
Polyps are typically unilateral and often follow a single episode of vocal abuse (shouting, screaming). Cysts are mucus-retention or epidermoid lesions. Both cause persistent hoarseness and usually require microlaryngoscopy for removal. Voice therapy before and after surgery significantly improves long-term outcomes.
Laryngopharyngeal Reflux (LPR)
Acid and pepsin from the stomach reaching the larynx — often without typical heartburn — cause chronic mucosal irritation producing morning hoarseness, voice fatigue, chronic throat clearing, globus (lump-in-throat sensation) and a persistent cough. LPR is significantly underdiagnosed. Treatment includes dietary modification (avoiding acidic foods, caffeine, alcohol, large evening meals), proton pump inhibitors and vocal hygiene. Response is gradual, typically over 2–3 months.
Vocal Cord Paralysis
Paralysis of one or both vocal cords produces a weak, breathy, aspiration-prone voice. Common causes include thyroid surgery, neck and chest surgeries, viral neuritis, and in a small percentage of cases, malignancy compressing the recurrent laryngeal nerve. All new-onset vocal cord paralysis requires urgent investigation to identify and treat the cause.
When to Suspect Malignancy
Hoarseness lasting more than three weeks — especially in a smoker or in anyone above age 45 — must be evaluated by laryngoscopy to exclude laryngeal carcinoma. Early-stage laryngeal cancer is highly curable; delayed diagnosis significantly worsens outcomes. Never assume persistent hoarseness is “just laryngitis” without visualising the cords.
What a Voice Assessment Involves
Assessment includes a detailed voice history (onset, pattern, aggravating factors, voice demands), flexible laryngoscopy to directly visualise the vocal cords, and in many cases stroboscopy to assess the vibratory pattern of the cords. Based on findings, treatment is individualised — voice therapy, medical management, surgery or further investigation as appropriate.
