Treatment of pediatric extra-axial sinogenic infection: case series and literature review

A Scoping Review of the Intracranial Complications of Pediatric Sinusitis

OBJECTIVE

Intracranial complications of pediatric sinusitis are uncommon but are often associated with significant morbidity, especially when appropriate care is delayed. The present study aimed to identify commonalities for the development and progression of these complications in the pediatric population.

DATA SOURCES

CENTRAL, CINAHL, Citation searching, ClinicalTrials.gov, Embase, Google Scholar, MEDLINE, PsycINFO, PubMed, Scopus, Web of Science, and World Health Organization.

REVIEW METHODS

A comprehensive literature search was performed using Preferred Reporting Items for Systematic Reviews and Meta-analyses scoping review guidelines. Studies describing intracranial infections secondary to sinusitis in the pediatric population (age <18 years) were included. Studies in which adult and pediatric data were not separated and studies in which the pediatric cohort was fewer than 10 cases were excluded. Ultimately, 33 studies describing 1149 unique patient cases were included for data collection and analysis.

RESULTS

Our analysis revealed intracranial complications were more common in adolescent males. Most children presented with over 1 week of vague symptoms, such as headache and fever. The majority of complications were diagnosed radiographically with computed tomography. Subdural empyema and epidural abscess were the most common intracranial complications reported. On average, patients were admitted for over 2 weeks. Most children were treated with a combination of antibiotics and surgical intervention. Complications were rare, but when present, were often associated with significant morbidity.

CONCLUSION

This scoping review of the available literature has provided insight into commonalities among pediatric patients who develop intracranial complications of sinusitis, providing a foundation for further study to inform medical and surgical decision-making in this population.

A 20-Year Study of Intracranial Pyogenic Complications of Sinusitis in Children

BACKGROUND

Intracranial pyogenic complications of sinusitis in children can lead to serious sequelae. We characterize the clinical, epidemiologic and microbiologic characteristics of children with such complications over a 20-year period.

METHODS

Single-center retrospective chart review. Cases were identified based on International Classification of Diseases diagnostic codes (ICD)-9 and ICD-10 depending on the year and by reviewing all intracranial microbiologic samples.

RESULTS

A total of 104 cases of complicated sinusitis were included after review of 1591 charts. Median age was 12 (IQR 9-14); 72 were male (69%). The most frequent complications were epidural empyema (n = 50, 48%), subdural empyema (n = 46, 44%) and Pott's puffy tumor (n = 27, 26%). 52% (n = 54) underwent neurosurgery and 46% (n = 48) underwent otolaryngologic surgery. The predominant pathogen isolated from sterile site specimens was Streptococcus anginosus (n = 40, 63%), but polymicrobial growth was common (n = 24; 38%). The median duration of intravenous antibiotic therapy was 51 days (IQR 42-80). Persistent neurologic sequelae (or death, n = 1) were found in 24% (n = 25) and were associated with the presence of cerebritis and extensive disease on neuroimaging ( P = 0.02 and P = 0.04, respectively).

CONCLUSIONS

Intracranial complications of sinusitis continue to cause significant morbidity in children. Polymicrobial infections are common, which reinforces the need for broad-spectrum empiric antibiotic therapy and cautious adjustment of the antibiotic regimen based primarily on sterile site cultures. The association of neurologic sequelae with the presence of cerebritis and extensive intracranial involvement on neuroimaging suggest that delayed diagnosis may be a contributor to adverse outcome.

Management of Intracranial Sinusitis Complications in Children and Adolescents: Similarities and Differences Among Otolaryngology Subspecialists

The purpose of this study was to compare the management of intracranial sinusitis complications in pediatric patients between members of the American Rhinologic Society (ARS) and the American Society of Pediatric Otolaryngology (ASPO). A cross-sectional web-based survey was distributed twice to the ASPO and ARS membership over an 8-month period. The overall survey response rate was 12.1% (7.5% of ARS members and 17.3% of ASPO members). Recommended management was similar with respect to the use of intravenous antibiotics, nasal saline irrigations, topical decongestants, and nasal steroid sprays. Recommendations diverged with regards to systemic steroid use and urgent/emergent endoscopic sinus surgery (ESS). ARS members were more likely to recommend systemic corticosteroids. ASPO members were more likely to recommend immediate ESS. Based on survey responses, we found differences in practice patterns among subspecialists, which indicates additional collaborative research between societies is necessary to develop and disseminate evidence-based guidelines for these patients.

Sinogenic Intracranial Suppuration in Children: Systematic Review and Meta-analysis

OBJECTIVE

To evaluate temporal trends in the management of sinogenic intracranial suppuration and its outcomes in children.

DATA SOURCES

A systematic search of databases was performed (Medline, Embase, Cochrane, ClinicalTrials.gov).

REVIEW METHODS

Studies in children (age <18 years) with sinogenic subdural empyema, extradural abscess, and intraparenchymal abscess were included. Data on treatment strategies were extracted. Primary outcome was death <90 days. Secondary outcomes were return to theater, neurologic disability at 6 months, and length of stay. Random effects meta-analysis and meta-regression were performed to investigate the effect of time and endoscopic sinus surgery (ESS) on these outcomes.

RESULTS

A total of 32 retrospective observational studies involving 533 patients recruited across a 45-year period (1975-2020) were included. The pooled estimates for 90-day mortality, permanent neurologic disability, and return to theater were 2.3% (95% CI, 1.1%-3.6%; I² = 0, P > .99), 21.3% (95% CI, 15.3%-27.3%; I² = 75.2%, P < .001), and 37.3% (95% CI, 29.5%-45%; I² = 71.2%, P < .001), respectively, with no significant differences found across the study period. The pooled estimate for ESS was 58.4% (95% CI, 44.2%-72.6%; I² = 97.1%, P < .001) with a significantly increasing trend in its use in the more recent years. ESS was not associated with improved mortality, reduced need for revision surgery, or neurologic disability.

CONCLUSION

The outcomes of sinogenic intracranial complications have not changed over the last 45 years, and ESS was not associated with improved patient outcomes. Further high-quality studies are required to determine the most appropriate treatment modalities to improve the burden of morbidity associated with sinogenic intracranial suppuration in children.
