Do vocal fold nodules typically form bilaterally?

• A. Yes, they typically form bilaterally
• B. No, they are always unilateral
• C. They form only on the left vocal fold
• D. They form only on the right vocal fold

Answer: (A)

Vocal fold nodules develop from chronic, abusive voice use causing localized swelling where the folds contact each other during phonation. Because both vocal folds participate in nearly every voice task, the same mechanical stress tends to affect them on both sides, leading to tissue changes at roughly the same place on each fold. This symmetric, repetitive trauma explains why nodules are most often found bilaterally. In rare cases, a lesion may appear on one fold due to asymmetric use or a different kind of pathology, but bilateral formation is the common pattern.
