Vocal fold nodules mainly occur in people who vocalize excessively. The main symptoms are hoarseness, roughness, easy involuntary interruptions during vocalization and other articulation problems, and some patients can be accompanied by sore throat. Endoscopic observation can reveal smooth fish-belly-like protrusions at the edges of the vocal folds. Vocal fold nodules mostly occur in people who vocalize excessively and use their voice incorrectly. These injury processes can cause uncoordinated stretching and tension in the vocal folds, and long-term stimulation can damage the vocal folds and lead to the creation of vocal fold nodules. The growth of vocal cord nodules can lead to hoarseness, shortness of breath, polyphony, vocal cord fatigue or loss of voice. The reason for these symptoms is mainly due to the growth of vocal cord nodules that affect the vibration of the vocal cords during articulation. Pain in the larynx is also another symptom of vocal cord nodules. This pain can be manifested as a slight foreign body discomfort or stinging discomfort in the larynx of varying degrees, which is mainly due to the local symptoms of inflammation associated with vocal cord nodules, and some patients may experience recurrent coughing due to these foreign body discomfort. Vocal fold nodules are easily detected laryngoscopically and have the appearance of polyps but with a wider base. There may also be signs of vasodilation and congestion on the nodules. Endoscopically, the nodules appear to have a smooth surface and a reddish color. Symptoms of vocal fold nodules are mainly manifested by abnormal pronunciation and non-severe pain as well as a peculiar endoscopic appearance.
