The NBI (Narrow Band Imaging) system is based on modification of the spectral features with an optical color separation filter narrowing the bandwidth of spectral transmittance. This imaging modality emphasizes the structure of the mucosal surface as well as capillary structures. We present a 74-year old man diagnosed with oropharyngeal superficial carcinoma by electronic fiberscope with NBI system for otolaryngologists. Surgery was successfully performed with minimal damage using a Davis mouth gag.
Using an electronic fiberscope with NBI system for otolaryngologists, superficial carcinomas can be more easily detected and methods of treating superficial carcinomas are facilitated.
Key words :superficial carcinoma, NBI, Davis mouth gag
