Abstract
We used video-bronchoscopy for the purpose of laryngopharyngeal observation. The Narrow Band Imaging (NBI) system on the video-bronchoscope was useful for the differential diagnosis of benign and malignant micro-lesions and for estimating the range of intraepithelial cancer lesions. It was easy to manipulate the bronchoscope for otorhinolaryngologists since it could be inserted transnasally. After the observation, a biopsy was performed immediately through the channel. Proper diagnoses were obtained in most of cases.
