Evaluation of Clinical and Laboratory Findings of Sinusitis Complications in Children

Objective This retrospective study evaluates the demographic characteristics, clinical symptoms, laboratory results, treatment approaches, and outcomes of children with complications arising from bacterial sinusitis. Methods Fifty-four pediatric inpatients with sinusitis complications admitted between September 2013 and October 2022 were included in the study. These patients were categorized into two groups: those with preseptal cellulitis (group 1) and those with orbital-intracranial complications (group 2). Results The median age of the patients was 10.8 years, and 61.1% were males. Maxillary sinusitis ( n = 40.74%) was the most common type of sinus involvement. Half of the patients exhibited preseptal cellulitis. The median age of our patients with intracranial complications was 13.7 years, while the median age of patients with orbital complications was 8 years. The predominant orbital-intracranial complication was meningitis, which accounted for 41% of the cases. All patients with a subdural abscess ( n = 6) presented with frontal sinusitis, while all cases of cavernous sinus thrombosis ( n = 3) involved the sphenoidal sinus. Surgical intervention was undertaken in 37% of cases. Streptococcus pneumoniae was the most frequently isolated microorganism. The median duration of hospital stay was 14 days, with a total median treatment duration of 21 days. There were no fatalities, although neurological sequelae were observed in 7.4% of patients ( n = 4). Conclusion Preseptal cellulitis and meningitis remain the most common complications of sinusitis in children. Adolescents with sinusitis should be monitored closely for intracranial complications. The prevalence of S. pneumoniae as the most frequently detected pathogen underscores the importance of vaccination.
