title: Sinonasal symptom assessment by the self-reported DyNaChron questionnaire: Before or after consultation?
abstract: OBJECTIVE
  Assessment of sinonasal symptoms on a self-reported questionnaire is thoroughly subjective, but indispensable for quantifying symptoms. The present study sought to compare responses on the DyNaChron questionnaire just before and just after consultation for chronic sinonasal dysfunction.
  
  
  METHODS
  78 patients (mean age, 43.1±16.9 years) consulting for chronic sinonasal dysfunction took part in a prospective study, responding to the computerized version of the DyNaChron self-reported questionnaire, in a dedicated room, just before and just after medical interview and physical examination.
  
  
  RESULTS
  Most patients tended to grade symptoms as less severe after consultation. Significant differences in mean score were found for nasal obstruction (difference of 0.94/10), anterior (0.40) and posterior rhinorrhea (0.26), olfactory disorder (0.65), and facial pain and headache (0.65), but not for chronic cough.
  
  
  CONCLUSIONS
  Self-reported scores for chronic sinonasal dysfunction differ slightly from before to after consultation. They are therefore to be interpreted with caution, taking account of possible factors of bias.
