The difference between vocal cord polyps and vocal cord nodules
Vocal cord polyps and vocal cord nodules are diseases caused by incorrect pronunciation or overuse of the voice, with the main clinical manifestation being hoarseness. The difference between vocal cord polyps and vocal cord nodules lies in their appearance under a laryngoscope: Vocal cord polyps often occur on one vocal cord, typically in the anterior one-third where a translucent, smooth swelling is found. This swelling can either have a broad stalk or a smaller stalk, and often, a hole can be observed with respiration. Vocal cord nodules are smaller and usually located symmetrically on the anterior one-third of both vocal cords. This implies that while polyps are commonly found on one vocal cord, nodules occur symmetrically on the anterior one-third of both vocal cords. From a general perspective, vocal cord polyps are wider and larger, whereas vocal cord nodules are only nodular lesions.
