title: [The value of narrow band imaging laryngoscope for laryngopharyngeal reflux disease].
abstract: OBJECTIVE
  To investigate the value of narrow-band imaging (NBI) laryngoscope for the diagnosis and therapy of the laryngopharyngeal reflux disease (LPRD).
  
  
  METHODS
  Analyzed the NBI laryngoscope characteristic findings of the throats of 46 LPRD patients which confirmed the diagnosis according to the reflux symptom index (RSI) and reflux finding score (RFS) both positive and the proton pump inhibitor therapy effective.
  
  
  RESULTS
  The NBI laryngoscope findings as follows: erythema and edema between the arytenoid cartilages (71.7%), the epiglottis congestion (67.4%), pharyngeal isolation/integration erythema (65.2%), pharyngeal pebbles--like changes (65.2%), hypertrophy of the posterior commissure (52.2%), vocal cord erythema and edema (47.8%), vocal nodules or vocal polyps with erythema, or edema (39.1%), arytenoid cartilages edema and erythema (21.7%), ventricular edema, erythema and laryngeal ventricle disappeared (17.4%), granuloma (6.5%), ulcers (4.3%), false vocal cord ditch (4.3%).
  
  
  CONCLUSIONS
  LPRD has characteristic findings. NBI laryngoscope is easy to operate and has a high value on the diagnosis and the treatment of the LPRD.
