Vocal polyp is a kind of benign hyperplastic lesion that mainly occurs in the superficial layer of the vocal cord lamina propria, and most of them can be removed by laryngoscopy under general anesthesia. One week after the operation, you need to strictly prohibit the voice, so that the vocal folds get enough rest, to avoid causing damage and bleeding. At the same time to avoid exertion, can be nebulized inhalation glucocorticoids to prevent and relieve the vocal cord edema. With proper care, normal voice can be resumed about one month after surgery, but be careful not to speak loudly and not to use your voice excessively. After surgery, you should reduce smoking, avoid exposure to dust and irritating gases, and maintain a light diet. After surgery for vocal polyps, you need to follow the doctor’s instructions for medication and treatment, and complete the recovery under the doctor’s guidance.
