Computed Tomography Imaging in Orbital Complications of Acute Inflammatory Paranasal Sinuses Diseases

Background: When it comes for identifying paranasal sinus disease (PSD) problems, CT scans are frequently the go-to imaging modality.
 Objective: To diagnose orbital complications of acute inflammatory paranasal sinuses diseases by computed tomography.
Patients and methods: Thirty patients with orbital complications as pain, edema, and visual acuity disorders were referred from Ophthalmology Department to Radiology Unit at Zagazig University Hospitals. All patients were included in this comprehensive sample trial and were subjected to thorough history and clinical evaluation as well as multi detector CT examinations.
Results: 40% had opacity in maxillary ethmoid bone (erosion), 30% had opacity in Max sphenoid ethmoid, 20% had opacity in maxillary ethmoid and 10% had maxillary opacity. Majority were invasive fungal (40%), allergic fungal (30%), acute bacterial with 20% and mucocale (10%). Significant association and agreement between Opacity in Max, sphenoid ethmoid and allergic fungal also between opacity in maxillary with mucocele and between opacity in maxillary ethmoid and acute bacterial also between opacity in maxillary ethmoid bone erosion and invasive fungal.
Conclusion: CT has important role in diagnosis of orbital complications resulting from acute inflammatory paranasal sinuses diseases, as it can detect cause, site of lesion, erosion of bone, and it can give feedback about response to treatment or need for surgical interference and success rate of surgery. CT could be with contrast or without contrast for better evaluation of lesion extension and invasion to surrounding structures.
