目的探讨老年人声嘶的常见病因和电视动态喉镜对声带良、恶性病变的早期诊断和鉴别诊断的价值。方法应用电视动态喉镜对２４３例老年声嘶患者检查结果进行分析。结果老年人声嘶的常见原因为声门闭合不全（６５例，占２６．７％）、喉癌（声门型，４８例，占１９．７％）、声带炎症（４５例，占１８．５％）和声带麻痹（４２例，占１７．３％）。梭形裂隙是声门闭合不全的常见形式。声带粘膜波动和声带振动的消失是喉癌的电视动态喉镜主要征象。结论（１）声带振动和粘膜波动的消失对声带恶性病变的诊断具有重要价值；（２）老年人声门闭合不全主要与声带肌肉张力减退、声带松弛有关；（３）老年人声带麻痹应警惕喉外恶性肿瘤所致。
Objective To investigate the common causes of hoarseness in the elderly and the value of dynamic video laryngoscope in the early diagnosis and differential diagnosis of benign and malignant vocal cord lesions. Methods Twenty-four elderly patients with hoarseness were analyzed with dynamic video laryngoscope. Results The common causes of hoarseness in the elderly were glottal insufficiency (65 cases, 26.7%), laryngeal cancer (glottis, 48 cases, 19.7%) and inflammation of the vocal cord (45 cases, 18%). 5%) and vocal cord paralysis (42 cases, 17.3%). Fusiform fissure is a common form of glottis insufficiency. Vocal cord mucosal fluctuations and vocal cord vibration disappear laryngeal cancer is the main dynamic video laryngoscope signs. Conclusions (1) Vocal cord vibration and disappearance of mucosal volatility have important value in the diagnosis of vocal cord malignant lesions. (2) The prevalence of glottis in the elderly is mainly related to vocal cord muscle tone loss and vocal cord relaxation. (3) Vocal cord paralysis in the elderly should be vigilant Laryngeal malignant tumors caused.
