Purpose:
To assess the value of orbital sonography (US) compared to CT in the management of children with ethmoid sinusitis.
Material And Methods:
A total of 13 consecutive patients admitted for non-complicated ethmoid sinusitis (absence of visual or neurological symptoms) were prospectively evaluated at US and CT.
Results:
Three patients had no evidence of postseptal involvement at US. Ten patients had variable degree of postseptal involvement at US: hypoechoic area or fluid collection in the extraconal fat along the medial orbital wall. Results were confirmed at CT in all patients.
Conclusion:
US is useful to confirm the presence of postseptal involvement in patients with ethmoid sinusitis. Contrary to CT, findings at US remain non-specific as to the nature of involvement. Nonetheless, US is helpful for patient management.
