Introduction
Vocal cord polyps are benign growths on the vocal cords. They typically develop due to prolonged improper voice use, vocal fatigue, smoking, alcohol consumption, and ingestion of spicy or irritating foods—factors that cause vocal cord hyperemia and edema. Chronic vocal cord edema may ultimately lead to polyp formation. Clinical manifestations are closely related to the location of the polyp. When located in the anterior to middle one-third of the vocal cord, the predominant symptom is hoarseness.
Vocal cord polyps are benign growths on the vocal cords. They typically develop due to prolonged improper voice use, vocal fatigue, smoking, alcohol consumption, and ingestion of spicy or irritating foods—factors that cause vocal cord congestion and edema. Chronic vocal cord edema may ultimately lead to polyp formation.
Clinical manifestations correlate directly with the location of the polyp. When located in the anterior-to-mid one-third of the vocal cord, the predominant symptom is progressive hoarseness, which worsens as the polyp enlarges.
If the polyp arises in the posterior portion of the vocal cord, patients may experience muffled or unclear voice quality, along with a sensation of a foreign body in the throat. As the polyp grows larger, severe cases may develop dyspnea (difficulty breathing) and/or dysphagia (difficulty swallowing). Laryngoscopy allows definitive diagnosis of vocal cord polyps; once confirmed, surgical intervention is mandatory.
