title: Subperiosteal abscesses in acute mastoiditis in 115 Swedish children.
abstract: OBJECTIVE
  To study the outcome of different surgical methods of treating subperiosteal abscesses resulting from acute mastoiditis.
  
  
  METHODS
  Medical records for all children from a Swedish retrospective multicentre study, conducted between 1993 and 2007, with acute mastoiditis and subperiosteal abscess, but without predisposing diseases or other complications, were studied. A total of 115 children aged 0-16 years were identified. All patients had received intravenous antibiotics and most had undergone myringotomy.
  
  
  RESULTS
  Thirty-three children had been treated with only minor interventions such as retroauricular needle aspiration and/or incision, while 67 had undergone mastoidectomy. Fifteen had undergone both needle aspiration and mastoidectomy. The group treated with needle aspiration/incision was compared with those treated with mastoidectomy. One of the few significant differences found between the groups was a longer hospital stay in the group that had undergone mastoidectomy.
  
  
  CONCLUSIONS
  Retroauricular needle aspiration and/or incision combined with intravenous antibiotics and myringotomy was an effective first-line treatment for subperiosteal abscesses resulting from acute mastoiditis. In this retrospective study, no greater risk of further complications was seen in this group compared to the group in which mastoidectomy was performed.
