Background:
The purpose of this study was to investigate differences in the extent of disease in patients with chronic rhinosinusitis (CRS) both with and without asthma.
Methods:
Medical records and computed tomographic (CT) scans of 48 consecutive asthmatic patients and 523 nonasthmatic patients with CRS between April 1995 and December 2001 were reviewed, retrospectively. Each sinus in the ostiomeatal complex CT scans was assigned a score of 0-2 according to the extent of disease using the Lund-Mackay scoring system, and the ratios of the score of each sinus to the total score were analyzed for the difference between the asthmatic and nonasthmatic groups. A Mann-Whitney test was used for statistical evaluation, with p < 0.05 accepted as statistically significant.
Results:
The ratios of ethmoid sinus score to total score were higher in asthmatic patients than in nonasthmatic patients (p < 0.001), and the ratios of the score of maxillary sinus to total score were lower in asthmatic patients than in nonasthmatic patients (p < 0.001).
Conclusion:
Our study shows that the ethmoid sinus is the preferred site of CRS in patients with coexisting asthma.

Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
