Relationship between patient-based descriptions of sinusitis and paranasal sinus computed tomographic findings.
OBJECTIVE
To evaluate the relationship of paranasal sinus symptoms with coronal computed tomographic (CT) findings.


METHODS
Prospective comparison of patient-based symptoms with imaging findings.


METHODS
Primary care and referral center office and hospital practices.


METHODS
Of 586 consecutive patients referred by otolaryngologists and primary care physicians for CT of the paranasal sinuses, 221 (151 women and 70 men; age range, 13-82 years; mean age, 44 years) participated by completing the Sino-Nasal Outcome Test-20 (SNOT-20) clinical questionnaire immediately before undergoing CT.


METHODS
Radiologists blinded to the patients' responses scored the degree of mucosal thickening at each of 12 sites on CT scans using a staged scale of severity (0-2 points). Bivariate analysis was performed to assess the relationship between patients' symptoms and CT findings.


RESULTS
The SNOT-20 scores ranged from 0 (normal) to 78 (mean, 34). The most commonly reported symptom was fatigue. The CT scores ranged from 0 (normal) to 24 (mean, 4.07). Seventy-five patients (34%) had normal findings on the CT scan. The maxillary sinus was the most commonly involved site (96 patients, or 43%). The SNOT-20 and CT scores failed to significantly correlate (r = 0.11, P < or = .09). When the subset of patients with "positive" or "very positive" CT scans were considered, no significant correlation was observed (r = 0.12, P < or = .16). For the 132 patients reporting facial pain, the mean CT score was lower than for patients without facial pain (3.78 vs 4.78, P = .21).


CONCLUSIONS
Patient-based reports of paranasal sinus symptoms failed to correlate with findings on CT scans; therefore, CT should be reserved for delineating the anatomy and pattern of inflammatory paranasal disease prior to surgical intervention.
