Dysphonia & Laryngeal Disease
Assess persistent voice change and identify structural or neurological causes.
Quick revision ↓ Medical Dictionary
01Describe voice change
Clarify hoarseness, weak voice, vocal fatigue, onset and duration. Ask about preceding infection, voice use, smoking, alcohol, reflux symptoms, intubation and neck or chest surgery. Associated stridor, swallowing difficulty, weight loss or a neck lump changes urgency. Persistent unexplained dysphonia needs laryngeal assessment rather than repeated treatment without visualising the relevant structures.
02Inflammatory and functional causes
Acute laryngitis commonly follows infection or voice strain and may improve with supportive care. Hydration and sensible voice use can help, while habitual forceful whispering may increase strain. Avoid assuming every hoarse voice is reflux or prescribing repeated antibiotics without evidence. Failure to improve or concerning features warrants reassessment.
03Benign lesions
Vocal fold nodules, polyps and other lesions can affect vibration and voice quality. Diagnosis generally requires laryngeal examination. Voice therapy has a role in selected disorders, and surgery may be appropriate for particular lesions. The functional needs of teachers, singers and other voice users matter when planning management and rehabilitation.
04Vocal fold immobility
Weak or breathy voice after relevant surgery can suggest vocal fold dysfunction, but the cause needs evaluation. Bilateral impairment can threaten the airway. Laryngoscopy and selected investigation assess the nerve pathway and structural causes. Do not assume postoperative hoarseness is harmless when it persists or is accompanied by aspiration or respiratory symptoms.
05Malignancy awareness
Persistent unexplained hoarseness, particularly with risk factors or other warning signs, needs the local suspected-cancer pathway. A normal oral examination does not exclude a laryngeal lesion. Explain the reason for referral without presenting suspicion as a confirmed diagnosis. Ensure results and further appointments have an identified responsible clinician or team.
High-Yield Revision
- Persistent unexplained voice change needs laryngeal assessment.
- A normal mouth examination does not exclude laryngeal disease.
- Voice function and airway function must both be considered.
Common Pitfalls
- Labelling all hoarseness as reflux without review.
- Ignoring aspiration or stridor after surgery.
