Vocal Cord Nodules and Polyps

Nodules vs. Polyps - Twin Troublemakers

• Etiology:
  • Nodules: Chronic vocal abuse (singers, teachers). "Singer's/Screamer's nodes".
  • Polyps: Acute vocal trauma, phonotrauma, smoking.
• Key Differences:

⭐ Vocal nodules are typically bilateral and symmetric, whereas polyps are often unilateral.

Clinical Presentation - Sounding Off-Key

• Hoarseness: Hallmark; often the only symptom.
  • Voice quality: Breathy, rough, raspy, strained.
  • Severity varies; may be intermittent.
• Vocal fatigue: Voice tires quickly during use.
• Effortful phonation: Sensation of needing to push voice out.
• ↓ Pitch range: Difficulty hitting high/low notes.
• Diplophonia (double voice) possible.
• Pain: Uncommon.
• Polyps: May present with sudden voice change (e.g., hemorrhagic polyp).

⭐ Hoarseness is the most common symptom, often worse with voice use and improving with rest, especially for nodules.

Diagnostic Spotlight - Larynx Unveiled

• Clinical Examination:
  • Indirect Laryngoscopy (IDL): Initial screening for vocal fold lesions.
  • Flexible Nasopharyngolaryngoscopy (NPL): Detailed dynamic view in OPD.
• Key Imaging - Stroboscopy:
  • Assesses mucosal wave, amplitude, symmetry, periodicity of vibration.
  • Helps differentiate nodules (often symmetric, impaired wave) vs. polyps (often unilateral, variable wave).

⭐ Stroboscopy is crucial for assessing vibratory patterns and differentiating benign lesions from early malignancy or other pathologies.

• Further Evaluation:
  • Direct Laryngoscopy (DL): Under GA for palpation, biopsy if atypia or diagnostic doubt. Microlaryngoscopy for precision.

Management Strategies - Restoring Harmony

• Conservative (First-line for Nodules, Small Polyps):
  • Voice Rest: Complete or modified.
  • Vocal Hygiene: Hydration, avoid irritants (smoking, alcohol, reflux).
  • Speech Therapy: Correct vocal misuse; voice exercises. 📌 Mnemonic: Rest, Hydration, Speech Therapy (RHS for Right Harmony Singers).
• Medical:
  • Treat underlying conditions: GERD (PPIs), allergies.
• Surgical (Phonomicrosurgery):
  • Indicated for: Large/pedunculated polyps, failed conservative therapy for nodules, suspicion of malignancy.
  • Techniques: Cold steel, microdebrider, CO₂ laser.

⭐ Voice therapy is the mainstay of treatment for vocal nodules, while polyps, especially large or pedunculated ones, may require surgical excision.

High‑Yield Points - ⚡ Biggest Takeaways

• Vocal cord nodules: Bilateral, at junction of anterior 1/3 & posterior 2/3 ("singer's nodes").
• Vocal cord polyps: Usually unilateral, often pedunculated, in Reinke's space (superficial lamina propria).
• Etiology: Nodules from chronic voice abuse; polyps from smoking, GERD, acute trauma.
• Key symptom: Hoarseness; also vocal fatigue, diplophonia.
• Diagnosis: Visualized by indirect laryngoscopy or stroboscopy.
• Treatment: Voice rest/speech therapy (nodules); microlaryngeal surgery (polyps/resistant nodules).
• Reinke's edema: Diffuse polypoid degeneration, strong smoking association, husky voice.
