Abstract

Objective: The objective of this study was to investigate the microbiological cultures and the management of acute ethmoiditis complicated by subperiosteal orbital abscess (SPOA) in a pediatric population.

Methods: The medical records of children under 18 years old was performed in a tertiary referral pediatric center from January 2009 to April 2017. Clinical examination, computed tomography scans, medical and surgical treatments were reviewed and compared to other studies in literature.

Results: One hundred and twenty-nine children were hospitalized for acute ethmoiditis. Among them, forty eight were complicated by SPOA. The mean age of these children were 7 years (range 10 months-16 years). Thirtyfour underwent surgical drainage; for the others the medical treatment was sufficient. Microbiological samples were obtained during the surgical intervention and were contributive in 91% of cases. Streptococcus spp was the most frequently encountered bacteria (60% of cases). We also found anaerobic bacteria (12%), and Staphylococcus aureus (12%). 94% of children received two intravenous antibiotics (a third-generation cephalosporin and metronidazole) for a mean duration of four days. Then the oral treatment was based on amoxicillin-clavulanate during about 8.5 days. All children were cured without sequelae.

Conclusions: For five years Streptococcus milleri, Staphylococcus spp and anaerobic bacteria are on the rise in acute ethmoiditis complicated by SPOA. That is why antibiotics must be adapted to these bacteria even in children under ten years old.
