Vocal cord polyp surgery requires general anesthesia, and exactly how long it takes depends mainly on whether the procedure goes well for the patient. If the vocal cords are well exposed, general anesthesia will take about 10 minutes. However, some people have a particularly high larynx, so it is not easy to expose the vocal cords after the laryngoscope, and then the surgery will take longer, and general anesthesia will take about 20 minutes, or even 30 minutes to complete. Some patients may not be able to expose the vocal cords and complete the surgery, it is recommended that patients speak as little as possible to reduce the friction of the vocal cords, the chances of vocal cord polyps will be significantly reduced, and 1 month after surgery need to return to the hospital to improve the laryngoscopy review.
