Pediatric Subperiosteal Abscess Secondary to Acute Sinusitis: A Systematic Review and Meta-analysis.

Laryngoscope 2020 December
OBJECTIVES/HYPOTHESIS: The surgical versus medical management of subperiosteal abscess can be controversial. The purpose of this study was to summarize current literature and provide pooled analyses to help direct management decisions.

STUDY DESIGN: Systematic review and meta-analysis.

METHODS: Patients <18 years old with subperiosteal abscess secondary to acute sinusitis were reviewed, and a meta-analysis was conducted. Studies including five or more patients written in English were the primary search focus.

RESULTS: Thirty-eight studies met inclusion criteria for the systematic review, and seven studies contained sufficient data for the meta-analysis. A total of 1,167 patients between the ages of 10 days and 18 years were included. Eleven sign/symptom categories were identified, with restricted ocular motility (n = 289, 45.9%), proptosis (n = 277, 44%), and fever (n = 223, 35.4%) being most frequent. Staphylococcus aureus was the most common pathogen isolated from cultures. Patients with abscess volume greater than the threshold specified in each individual study were over three times more likely to require surgical intervention compared to those with smaller abscess volume (pooled risk ratio [RR] = 3.61, 95% confidence interval [CI]: 2.40-5.44). Proptosis and gaze restriction also significantly predicted surgical intervention (pooled RR = 1.65: 95% CI: 1.29-2.12 for proptosis/pooled RR = 1.90; 95% CI: 1.20-3.00 for gaze restriction).

CONCLUSIONS: Approximately half of patients with a subperiosteal abscess undergo surgical drainage. Abscess volume appears to be the most significant predictive risk factor. Detailed data from future studies regarding radiologic and ophthalmologic parameters are needed to provide more definitive values predictive of which patients are likely to fail medical therapy.
