Computed tomography imaging of the maxillary and ethmoid sinuses in children with short-duration purulent rhinorrhea.
BACKGROUND
Adults with a common cold often have paranasal sinus effusions detected by computed tomographic (CT) scans. There are no comparable data for children. The purpose of this study was to document the sinus CT findings in children with short-duration purulent rhinorrhea.


METHODS
Thirty children, 3 to 12 years of age (median age, 7 years), with purulent rhinorrhea for a mean duration of 5 days (and always less than 9 days) were enrolled in the study. The children were otherwise well. Institutional Review Board (IRB)-approval was obtained before enrollment of the first patient. Informed written consent was obtained from each child's parent. CT imaging of the maxillary and ethmoid sinuses was obtained on the day of the initial visit (occasionally, the following day). Follow-up CT scans were obtained from cooperative children/parents, 3 to 4 weeks later.


RESULTS
Opacification or an air/fluid level in the maxillary sinuses was seen in 27 (90%) of 30 study children at study entry. Ethmoid sinuses were not opacified without opacification of a maxillary sinus. Three weeks later, 24 of 27 study children, who had positive CT scans on study entry, improved clinically. Of 17 follow-up CT scans, 10 (58%) normalized, 4 had improvement of bilateral disease, and 3 improved with unilateral disease. None appeared worse than baseline.


CONCLUSIONS
Pansinus opacification (ethmoid and maxillary sinuses), on CT scans in children with short-duration purulent nasal drainage was seen in 70% of children. An additional 20% had isolated maxillary sinus effusions (10% had no effusion). Three-week follow-up CT scans on 17 children were normal in 60% and improved (partial clearance) in 40%. In this patient population, the decision to treat with antibiotics should be made on clinical grounds alone.
