title: Reliability assessment of the endoscopic examination in patients with allergic rhinitis.
abstract: OBJECTIVE
  To study if nasal endoscope can be a reliable tool in assessing patients with allergic rhinitis.
  
  
  METHODS
  A prospective study. Patients who were diagnosed with allergic rhinitis underwent a nasal endoscopic examination performed by two physicians blinded to the scoring of each other. A correlation was made among symptom severity, endoscopic findings, and interrater variability.
  
  
  RESULTS
  Ninety patients were included in the study: 34 patients had mild disease and 56 had moderate-to-severe allergic rhinitis according to the Allergic Rhinitis and its Impact on Asthma guidelines. Increases in mucosal edema and bluish discoloration were predictive of the severity of allergic rhinitis disease (p < 0.05). The presence of nasal secretions was not predictive of allergic rhinitis. Interrater reliability was fair for mucosal edema, moderate-to-almost perfect for the rest of the endoscopic findings.
  
  
  CONCLUSIONS
  Nasal endoscopy may reveal signs that are predictive of the severity of allergic rhinitis. A detailed checklist is needed for the nasal endoscopic examination to decrease interrater variability.
