title: Complications of acute otitis media in children in southern Finland.
abstract: BACKGROUND
  The incidence of intratemporal and intracranial complications of acute otitis media (AOM) has decreased and the need for operative treatment is declined in developed countries during the antibiotic era.
  
  
  OBJECTIVE
  To establish the clinical picture, diagnostic procedures, outcome and current treatment of pediatric patients with intratemporal and intracranial complications of AOM.
  
  
  METHODS
  A retrospective chart review with a sent questionnaire. All pediatric patients treated for intratemporal and intracranial complications of AOM over the past 10 years (1990-2000) at the Department of Otolaryngology in the Helsinki University Central Hospital.
  
  
  RESULTS
  During the study period 33 children (incidence 1.1/100,000 per year), aged from 3 months to 14.2 years were treated for intratemporal [97% (32/33)] and intracranial [3% (1/33)] complications of AOM. Facial paresis was found in 9% (3/33) of the patients. The only intracranial complication was an extradural abscess with meningitis. Eighteen patients (55%) were on antibiotic treatment because of AOM prior to the diagnosis of complication. Neither the duration or severity of the signs and symptoms of infection at the time of admittance nor a lack of antibiotic treatment before admittance were statistically significantly associated with the need for mastoidectomy or duration of hospitalization. Streptococcus pneumoniae 25% (8/33) and Pseudomonas aeruginosa 22% (7/33) were the most frequently found bacteria in the culture of middle ear and mastoid effusions. Mastoidectomy was performed on 55% (18/33) of the patients. After half a year of follow-up, all the patients had normal hearing and facial function.
  
  
  CONCLUSIONS
  Severe complications of AOM are rare today in southern Finland and the need for mastoidectomy has declined significantly. With early recognition and effective treatment of complications, the prognosis is good.
