Muscle tension dysphonia is best described as?

• A. A speech diagnosis characterized by variable symptoms of voice disruption in the absence of laryngeal pathology and caused by visible or palpable tension or stiffness of the neck, jaw, shoulders, and throat.
• B. A structural lesion such as a vocal fold polyp.
• C. A degenerative neuromuscular disease.
• D. Inflammation of the vocal folds due to reflux.

Answer: (A)

Muscle tension dysphonia is a functional voice disorder where voice disruption occurs without any structural lesion in the larynx. The problem isn’t a mass or disease of the vocal folds, but excessive tension in the muscles around the voice system—often visible or palpable in the neck, jaw, shoulders, or throat. That tension changes how the vocal folds vibrate and how phonation is produced, leading to hoarseness, strain, pitch instability, or voice fatigue that can vary over time.

This condition is diagnosed when there’s no laryngeal pathology to explain the voice changes, and it’s typically addressed with therapies aimed at reducing muscular tension and teaching more efficient voice use. It’s different from conditions caused by structural lesions (like a vocal fold polyp), degenerative neuromuscular diseases, or inflammatory conditions related to reflux, which would involve distinct anatomical or inflammatory findings.
