目的：为提供临床诊断和鉴别诊断喉部疾病的客观依据。方法：对我科近8年来检查的3411例声嘶程度不同患者的动态电视喉镜检查图像结果进行分析。结果：声带浅层病变，对声带振动和粘膜波动的影响较小；声带深层的病变，其声带振动和粘膜波动可减弱或消失；声带麻痹两侧声带的粘膜振动不对称，不协调。结论：声带色泽、形态及振动模式的改变，是喉部疾病的特征。
Objective: To provide an objective basis for clinical diagnosis and differential diagnosis of laryngeal diseases. Methods: The results of dynamic video laryngoscopy in 3411 patients with different degrees of hoarseness in our department in the recent 8 years were analyzed. Results: The superficial lesions of the vocal fold had little effect on vocal cord vibration and mucosal fluctuations. Vocal cord vibration and mucosal fluctuations could be attenuated or disappeared in the deep lesions of the vocal cord. The vocal cords vibrated asymmetrically and uncoordinated on both sides of the vocal cord paralysis. CONCLUSIONS: Changes in vocal cords color, morphology and vibration patterns are characteristic of laryngeal disease.
