title: Lack of significant correlation between rhinosinusitis symptoms and specific regions of sinus computer tomography scans.
abstract: BACKGROUND
  The sinonasal computer tomography (CT) scan is frequently used to help confirm the diagnosis of rhinosinusitis. However, little data exist correlating patient symptoms with CT findings.
  
  
  METHODS
  Immediately preceding CT of the sinuses, 94 subjects without evidence of trauma, nasal tumors, or previous sinus surgery completed the Rhinosinusitis Outcome Measure 31 symptom questionnaire and were asked to locate areas of facial pain or pressure. CT scans were graded according to the Lund-MacKay system, and agger nasi and ethmoid bulla cells were measured. Data from CT scans and symptom/pain questionnaire responses were analyzed for significant correlations.
  
  
  RESULTS
  No correlation was identified when comparing total Lund-MacKay scores, opacification of individual sinuses, and size of the agger nasi and ethmoid bulla cells with the Rhinosinusitis Outcome Measure 31 subset scores and areas of facial pain or pressure.
  
  
  CONCLUSIONS
  The sinus CT scan is a necessary tool for preoperative planning; however, it should not be used to predict symptoms or to localize areas responsible for facial pain or pressure.
