绝大多数的声带功能紊乱经间接喉镜或直接光纤喉镜检查可以获得满意的结果。当遇到患者不合作或巨大的声门上区肿瘤时要用喉镜检查就会遇到困难。B超检测声带也是一种可采用的方法，但由于发阶图像不易分辨声带的微小运动，而且B超仅能检测固定组织，并不能检测或分析气流状态
The vast majority of vocal cord disorders can be satisfied with indirect laryngoscopy or direct fiberoptic laryngoscopy. Difficulties are encountered with laryngoscopy when encountering patients with uncooperative or massive supraglottic tumors. B ultrasound detection of vocal cords is also a method that can be used, but due to the low-level images are not easy to distinguish the slight movement of the vocal cords, and B ultrasound can only detect fixed tissue and can not detect or analyze the airflow state
