Introduction

An increase in both the incidence and severity of acute mastoiditis (AM) has been recently recorded in many different geographical areas. Causes remain unclear.

This study aims to evaluate our clinical and epidemiological data in paediatric patients with AM and to compare them with recent reports.

Material and methods

Retrospective chart review of 145 patients diagnosed of AM from 1999 to 2008 in our tertiary-care centre, including clinical, epidemiological, microbiological, treatment and outcome data.

Results

The annual incidence showed a changeable trend throughout the study period. The average number of cases was 14.5 cases per year, with a median age of 3 years, and 57.9%males. A total of 53.8%received pre-admission oral antibiotics, mainly beta-lactamics. Most frequent presenting clinical findings were fever (77.9%), ear displacement (73.8%), otalgia (71.7%), and postauricular swelling (70.3%). Microbiological cultures were performed in 53 cases; S. pneumoniae was the most isolated microorganism. CT scans were performed in 56.6%cases. All patients received parenteral antibiotic treatment with a median duration of treatment of 5 days. Surgery was performed on 32.6%. Complications were seen in 20%of patients: 13.1%had extracranial complications, and 8.2%had intracranial complications. A significant increase in intracranial complications was detected in the second half of the study period.

Conclusions

A changeable trend in the annual incidence of AM throughout the time of study was observed. A higher proportion of intracranial complications was detected in the last five years of the study period.
