Disease Description (Causes and Symptoms)
- Definition: A lesion consisting of a small nodule (millet seed to rice grain in size) that develops on the vocal cord mucosa due to persistent vocal abuse or excessive vocal strain. It usually occurs bilaterally at the junction of the anterior one-third and middle one-third of the vocal cords.
- Causes and pathophysiology: Repeated vibration irritates the vocal cord mucosa and submucosa, causing edema, vasodilation, congestion, and hemorrhage. Thickening and fibrosis of the basement membrane progress, causing the nodules to become firm. It is common in young boys (approximately 6–7 years old), women in their early 30s, and people with occupational voice overuse, such as singers and teachers. Compensatory hyperfunctional voice use due to conditions such as cleft palate may also be a cause.
- Main symptoms: Persistent hoarseness, diplophonia (duplicated voice), vocal fatigue, voice splitting at high pitches (breaks), and worsening when singing. Airway obstruction and malignant transformation are usually rare.
Treatment Methods
- Conservative treatment (first-line treatment)
- Voice rest (temporary silence or minimizing voice use) and voice therapy (voice training by a speech/voice therapist, correction of breathing and phonation patterns) — improvement occurs in a substantial proportion of cases (approximately 80% or more).
- Environmental and lifestyle management: Adequate humidification, smoking cessation, fluid intake, limiting excessive caffeine and alcohol, and improving vocal technique.
- Treatment of accompanying conditions: If laryngeal or laryngopharyngeal reflux is suspected, dietary modification and medication (such as PPIs), as well as treatment for allergies and upper respiratory tract infections.
- Duration: Conservative treatment for at least 3 months is generally recommended.
- Surgical treatment (indications)
- When symptoms persist despite at least 3 months of conservative treatment, or when early functional recovery is necessary for occupational reasons.
- Surgical methods: Microscopic laryngeal microsurgery (forceps excision), CO2 laser, microflap technique, and others — the goal is to preserve the mucosal wave by minimizing unnecessary removal of the mucosa.
- After surgery: Strict voice rest and rehabilitation (voice therapy) to prevent scar tissue and fibrosis.
- Medication
- There is no specific medication that dissolves the nodules themselves. Short-term treatment may be considered only for acute inflammatory edema (at the physician’s discretion). Medications are mainly used to treat reflux, allergies, and infections.
- Precautions
- Even after surgery, the nodules may recur if incorrect vocal habits continue.
- Once the condition becomes chronic, treatment becomes more difficult due to fibrosis.
Checklist Before an Outpatient Visit (Including Items to Bring and Example Questions)
- Items and information to bring
- A list of currently used medications and supplements (name, dosage, and duration of use)
- When symptoms began and how they have progressed (intermittent/continuous, aggravating factors), and occupation (amount of occupational voice use)
- Recordings that clearly demonstrate the voice change (mobile phone recordings), and videos showing problems when singing or speaking (if possible)
- Previous otolaryngology examination results or laryngoscopy photos/videos (if available)
- History of previous voice therapy or surgery, smoking and alcohol use, and reflux symptoms (heartburn and cough)
- Examples of information to tell the doctor in advance at the outpatient visit
- The date when symptoms first began and their pattern of worsening/improvement
- The type of vocal use involved (singing, lecturing, telephone counseling, etc.) and the number of hours per day the voice is used
- Whether accompanying symptoms such as recent shortness of breath, difficulty swallowing, or weight changes are present
Examples of General Questions to Ask the Doctor
- What are the main effects and side effects of this medication (or treatment)?
- How quickly can symptoms improve with conservative treatment? What are the criteria for determining that it has failed?
- If surgery is recommended, what degree of improvement can be expected, and what are the risks (such as bleeding, scarring, and voice changes)?
- What daily management measures (such as limiting voice use and lifestyle changes) can reduce the risk of recurrence?
Examples of Condition-Specific Questions
- For professional voice users (singers and teachers): "Can I recover professional-level vocal function with conservative treatment alone? When can I expect to return to work?"
- For children or patients with a history of cleft palate: "When velopharyngeal insufficiency is present, how should the treatment priorities for vocal cord nodules and any additional corrective treatment (for example, cleft-palate-related treatment) be coordinated?"
