Vocal cord polyps are non-cancerous growths that develop on one or both vocal cords (vocal folds). These fluid-filled or gelatinous lesions form when blood vessels in the vocal cord rupture, usually due to vocal trauma or chronic irritation. Unlike vocal nodules which are typically bilateral and harder, polyps are often unilateral and softer in consistency.
The vocal cords are two bands of smooth muscle tissue located in your larynx (voice box). When you speak, air from your lungs causes these cords to vibrate, producing sound. Polyps can interfere with this normal vibration pattern, potentially resulting in voice changes. Environmental factors like air conditioning, pollution, and high voice use in professional settings may contribute to the development of this condition.
