Narrow‐band Imaging Combined With Magnified Endoscopy for Cancer at the Head and Neck Region

While detection of lesions at an earlier stage in head and neck mucosal sites would obviously be of great merit to patients, there has been no modality to discover such lesions. Herein, we investigate a possibility of clinical application of narrow‐band imaging (NBI) endoscopy, which is a brand new optical technique that allows non‐invasive visualization of the microvessels at the organ surface. We found that NBI technology could be a promising and powerful tool for identifying carcinomas at an earlier stage in head and neck mucosal sites. This may open a new door in the field of head and neck oncology.
