Secondary surgery for vocal cord polyps is associated with the possibility of malignant changes. Vocal cord polyps are caused by improper long-term vocal usage, fatigue from overuse, shouting loudly, smoking, drinking, and irritation from acid reflux, leading to vocal cord lesions. It causes the patient to have persistent hoarseness of voice, which progressively worsens. Examination with an electronic laryngoscope may reveal a pale white or pale red abnormal neoplasm at the anterior middle third of the unilateral vocal cord. This can lead to incomplete closure of the glottis, resulting in hoarseness of voice. In terms of treatment, medicating vocal cord polyps is ineffective, and the patient must undergo a polypectomy under suspension laryngoscopy. The surgery requires hospitalization and general anesthesia, and the patient can usually recover and be discharged within about a week. After discharge, the patient needs to speak softly and infrequently, follow a bland diet, and abstain from smoking and drinking to prevent recurrence. If recurrences occur, the vocal cord polyps may have the potential to turn cancerous.
