Vocal folds are usually raised due to acute laryngitis, chronic laryngitis, benign masses or malignant tumors, etc., which need to be treated as soon as they are detected.
1. Acute laryngitis can cause the surface of the vocal folds to become congested and edematous, resulting in a bump on the surface of the vocal folds, which can lead to breathing difficulties, hoarseness and other symptoms.
2. Chronic laryngitis can cause the surface of the vocal folds to thicken and bulge, resulting in symptoms such as hoarseness, breathlessness, and in severe cases, loss of voice.
3. Vocal polyps or cysts and other benign swellings may also cause the surface of the vocal folds to thicken and bulge, which in turn may lead to the bulging of the vocal folds.
4. When laryngeal cancer occurs, it may invade both vocal cords, which may cause the surface of the vocal cords to bulge, resulting in hoarseness, dyspnea and other symptoms, and in serious cases, it may cause metastasis to the surrounding lymph nodes.
It is recommended to consult a doctor to clarify the cause of the disease and then carry out targeted treatment.
