Patients with laryngeal lesions were observed and the lesions were recorded with an electronic videoendoscope system using the PENTAX EPM-3300 video processor and the PENTAX VNL-1330 endoscope portion. The electronic videoendoscope system differs from the conventional fiberoptic endoscope connected to a video camera in that a small monochrome charge-coupled device (CCD) chip is built in the tip of the endoscope portion. The PENTAX VNL-1330 rhinolarynx endoscope portion has a tip and insertion tube of approximately 4mm in outer diameter to allow its introduction through the nasal passages into the larynx. The dynamic color images provided by this system were superior to those obtained by a conventional rhinolarynx flexible fiberscope connected to a video camera in both quality and resolution of detail. This system should be useful in diagnosing laryngeal lesions.
对喉部病变患者进行观察，并使用宾得EPM - 3300视频处理器和宾得VNL - 1330内窥镜部分的电子视频内窥镜系统记录病变情况。电子视频内窥镜系统与连接到摄像机的传统纤维光学内窥镜不同，在于内窥镜部分的尖端内置了一个小型单色电荷耦合器件（CCD）芯片。宾得VNL - 1330鼻咽喉内窥镜部分的尖端和插入管外径约为4mm，以便通过鼻道插入喉部。该系统提供的动态彩色图像在质量和细节分辨率方面均优于连接到摄像机的传统鼻咽喉柔性纤维镜所获得的图像。该系统应有助于诊断喉部病变。
