A hoarse speaking voice is a symptom that clinicians call hoarseness. Hoarseness indicates a problem with the organ responsible for articulation, which is the larynx, and more specifically the vocal cords. The presence of hoarseness can be caused either by a lesion in the vocal folds themselves or by a lesion in the larynx that involves the vocal folds. Regardless of the cause, hoarseness occurs when the lesion causes the vocal folds to fail to achieve normal motion during pronunciation. The common diseases that lead to hoarseness: 1, inflammatory diseases: including acute inflammation and chronic inflammation, acute inflammation commonly have acute laryngopharynx, acute epiglottitis, etc., need to be treated as soon as possible, chronic inflammation is mainly chronic inflammatory changes in the vocal cords, such as reflux laryngitis, etc. 2, benign lesions of the vocal cords: such as vocal cord nodules, vocal cord polyps, vocal cord white spots, vocal cord cysts, contact granuloma, laryngeal nodules, larynx Most of these cases need surgery. 3.Malignant tumor of larynx: laryngeal cancer (vocal fold type, supraglottis type, infraglottis type), hypopharyngeal cancer involving the larynx. 4.Thoracic tumors compressing nerves: such as esophageal cancer, mediastinal tumors, etc. compress the nerves governing the vocal folds, resulting in abnormal vocal fold movement. 5.Injury to the nerve after neck trauma or neck surgery: such as neck impact injury, neck thyroid surgery, etc., are mostly caused by injury to the nerve that governs vocal cord movement.
