Diagnosis and grading of laryngopharyngeal reflux disease with narrow band imaging: preliminary study
Purpose
Laryngopharyngeal reflux (LPR) disease is a common problem usually diagnosed with white light laryngoscope and questionnaires. Some studies have proposed Narrow band imaging (NBI) laryngoscopy as a useful method for diagnosing LPR. The aim of this preliminary study was to evaluate the potential use of NBI for the diagnosis and grading of LPR disease.
