Narrow band imaging endoscopy of the nasopharynx is not more useful than white light endoscopy for suspected nasopharyngeal carcinoma

Abstract

Endoscopy is often used to screen for nasopharyngeal carcinoma. A normal nasopharynx on white light endoscopy may yet harbor subclinical or occult malignancy. This study assessed whether the vascular pattern seen on narrow band imaging endoscopy could indicate this and thus be useful for detecting suspected nasopharyngeal carcinoma.
