Vocal cord polyps refer to grayish white, smooth polyp-like tissues that occur on the front and middle edge of one side of the vocal cord. They are mostly single or multiple on one side, with a pedicle or a broad base, often grayish white and translucent, or small red protrusions. Those with pedicles often move up and down with breathing, and large ones can block the glottis and cause breathing difficulties, affecting pronunciation. They are mostly located at the junction of the front and middle thirds of the vocal cords. Generally, vocal cord nodules in children do not need to be treated for the time being, while nodules or polyps in adults generally require surgery. After surgery, routine vocal abstinence should be used and nebulization treatment can be performed. At the same time, attention should be paid to pronunciation methods and excessive phonation should be avoided to prevent recurrence.
