Abstract
Summary
Objective: To describe the images characteristics and role of computed tomography in the orbital infections due to sinusitis. Subject and method: Retrospective descriptive study of patients diagnosed and treated for orbital infections due to sinusitis at National Ear Nose Throat Hospital and Bach Mai Hospital from January 2018 to April 2020. Result: Total 26 patients, mean age 35.7 ± 24.6 (3 - 84 years), female/male = 1.2 : 1. The most common sinusitis position was anterior ethmoid sinus accounting for 84.6%. Sinus wall disruption was seen in 21/26 patients (80.8%), of which paper bone discontinuity was found in 20/21 (95.2%). The image of orbital lesions on computed tomography included: Eyelid thickening and enhancement (77%), posterior eyeball fat infiltration (30.8%), subperitoneal abscess (65.4%), posterior eyeball abscess (3.8%). Orbital inflammation classification according to Chandler: Group I (15.4%), group II (15.4%), group III (65.4%), group IV (3.8%), group V (0%). The diagnostic value of CT scanner compared with surgery was very suitable with Kappa index > 0.8. Conclusion: CT scanner is a highly valuable method in the diagnosis of orbital inflammation due to sinusitis, contributing to treatment planning for patients.
Keywords: Sinusitis, orbital inflammation due to sinusitis, orbital complications, computed tomography.
