It usually takes about a month for a polyp to return to normal after surgery, and may take longer if an infection develops. Laryngeal polyp is a benign lesion that occurs in the larynx, the main symptoms are hoarseness, coughing, change in pitch, etc. Generally, after diagnosis, surgery is usually considered, and the commonly used surgical method is laryngoscopic polypectomy, which requires 2 days of hospitalization for observation and 2 weeks of vocal abstinence, and then 2 weeks of gradual resumption of voice, and a month later, it is basically back to normal. However, some patients may not be able to control the upper respiratory tract infection after the surgery. The infection will cause the laryngeal mucosa and vocal folds to become congested and swollen, thus affecting the wound healing, and it may take a longer period of time to return to normal.
