Dysphonia, or hoarseness, is a symptom (not a diagnosis) produced by roughening or abnormal movement of the vocal folds. A diagnosis can only be made by viewing the vocal folds. Because of the excellent prognosis for laryngeal carcinoma that is treated early, all patients who complain of dysphonia deserve to have this diagnosis excluded.
发音障碍，即声音嘶哑，是由声带粗糙或异常运动产生的一种症状（而非诊断结果）。只有通过查看声带才能做出诊断。鉴于早期治疗的喉癌预后良好，所有主诉发音障碍的患者都应排除这种诊断。
