We performed endoscopic phonosurgery in a patient with a laryngeal lesion using a prototype of the therapeutic rhino-larynx electronic endoscope connected to a video processor (Asahi Optical Co., Ltd.). This therapeutic electronic endoscope differs from the fiberoptic endoscope, because it contains an instrument channel and a miniature television camera attached to the tip of the endoscope, consisting of a small light-sensitive CCD chip. The dynamic image provided by this system is superior in resolution to that obtained by conventional flexible laryngofiberscopes. Using this therapeutic electronic endoscope and flexible forceps, we succeeded in removing a vocal fold polyp. This endoscope can be passed through the nasal passage into the laryngeal cavity. The therapeutic electronic endoscope is introduced and a clinical case is presented.
我们使用连接到视频处理器（旭光学株式会社）的治疗性鼻咽喉电子内窥镜原型，对一名患有喉部病变的患者进行了内镜嗓音外科手术。这种治疗性电子内窥镜与纤维内窥镜不同，因为它有一个器械通道和一个连接在内窥镜尖端的微型电视摄像机，该摄像机由一个小型感光电荷耦合器件芯片组成。该系统提供的动态图像在分辨率上优于传统的软性纤维喉镜所获得的图像。使用这种治疗性电子内窥镜和软性钳子，我们成功地切除了一个声带息肉。这种内窥镜可以通过鼻腔进入喉腔。介绍了这种治疗性电子内窥镜并展示了一个临床病例。
