ABSTRACT
OBJECTIVE: To assess clinical, laboratory, and microbiological differences between children with simple and complicated mastoiditis. PATIENTS AND METHODS: Data on all children who were hospitalized at a tertiary center for acute mastoiditis over a 5-year period were collected from the computerized files. Findings were compared between those with simple mastoiditis vs. cases with intra- or extra-cranial complications. RESULTS: Of the 308 children with acute mastoiditis, 55 (17.9%) had complicated disease. This group was characterized by a significantly higher maximal fever at presentation and higher absolute neutrophil count and C-reactive protein level than the children with simple disease. There was no statistically significant between-group difference in age, history of otitis media, prior antibiotic treatment, days of illness before presentation, absolute leukocyte count, and platelet count. No difference was detected between the groups in the penicillin and ceftriaxone susceptibility of the Streptococcus pneumoniae isolates. CONCLUSION: High-grade fever, high absolute neutrophil count, and high C-reactive protein level may serve as clinical and laboratory markers of complicated mastoiditis. Children with these findings warrant close follow-up and perhaps, earlier surgical intervention.
