Objectives: Assess characteristics and outcomes of orbital complications of acute bacterial rhinosinusitis (ABRS) in the pediatric population and evaluate trends over time.
Methods: A literature search of pediatric orbital complications was performed in the following databases: Ovid MEDLINE, Scopus, and Cochrane Database of Systematic Reviews. Studies reporting data for at least 10 subjects with orbital complications of sinusitis under 18 years old were included. Studies were grouped by publication year; before 2010 and after and including 2010. Studies that only included patients with subperiosteal abscess (SPA) were grouped in a separate category. Data collected include demographics, Chandler class complications, intra-operative culture, treatment, and outcomes. Meta-analysis of proportion was performed to compare data from studies published before 2010 and data published in 2010 and after.
Results: Thirty-five studies met inclusion criteria. No significant difference was observed over time in gender of subjects in the all Chandler complications or SPA only groups (P > 0.72). The proportion of subjects presenting with Chandler IV complications decreased from 6.8% to 2.9% in recent studies (P = 0.019). The proportion of subjects treated surgically decreased from 45.2% to 21.7% in the all Chandler complications group (P < 0.0001) and from 90.0% to 47.9% in the SPA only group, P < 0.0001. The proportion of S. pneumoniae positive cultures decreased from 20.5% to 9.1% (P = 0.02).
Conclusion: The demographics of pediatric patients treated for orbital complications of ABRS in published literature has been stable. Patients reported in more recently published studies are less likely to present with orbital abscess and more likely to receive conservative treatment. The proportion of positive Streptococcus pneumoniae cultures have decreased.
