Mabrouk AB, Wannes S, Hasnaoui M, et al. - From the database of a single academic paediatric care centre, researchers identified and analyzed patients with orbital extension of acute ethmoiditis registered over a period of 14 years, to determine the clinical, biological and radiological characteristics of orbital complications as well as to explore predictors of severe ophthalmological lesions and/or associated cerebral complications of acute ethmoiditis in this cross sectional analysis. This study involved 16 patients (12 girls and 4 boys) among 39 consecutives cases of ethmoiditis recessed with a complication rate of 41%. Average consultation delay was 4.88 days. The study sample had a mean age of 4.37 years. Findings revealed frequent orbital complications of ethmoiditis. The severity of orbital lesions was not predicted by any clinical or biological criteria. In the identification of eventual complications on time, assistance could be offered by both orbital and brain CT scan.
