Speaking hoarseness is mainly due to laryngeal lesions, such as the vocal folds and ventricular zone after the occurrence of lesions, which may affect vocalization. The specific causes are as follows: 1, inflammation: acute pharyngitis, acute laryngitis or chronic laryngitis can cause hoarse speaking voice, and must be carefully examined under laryngoscopy to observe whether there is inflammation in the vocal folds on both sides, whether it is acute inflammation or chronic inflammation; 2, vocal fold masses: including benign masses and malignant masses. The most common benign masses are vocal fold nodules, vocal fold polyps, vocal fold papillomas, cysts; malignant masses in the vocal folds, such as laryngeal cancer; 3. Vocal fold paralysis: poor or restricted movement of one side of the vocal folds, or incomplete paralysis or complete paralysis can cause hoarseness of speech. Therefore, it is important to clarify the causes of hoarseness and take the correct treatment according to the different causes to relieve hoarseness.
