title: Medical treatment of pediatric subperiosteal orbital abscess secondary to sinusitis.
abstract: BACKGROUND
  Subperiosteal abscess may accompany orbital cellulitis secondary to sinusitis. Common surgical principles include incision and drainage of all abscesses. Previous evidence suggests that some orbital abscesses may be treatable with intravenous antibiotics, especially in young children. Children's hospital records were reviewed to determine which abscesses may be treated medically.
  
  
  METHODS
  Records of patients admitted for orbital cellulitis from 1993 to 1996 were reviewed. Patients with subperiosteal abscess on CT scan were included. Clinical outcomes for initial surgical versus medical management of medial abscesses were compared. Differences in age, hospital stay, and intracranial involvement were analyzed for medial versus nonmedial abscesses.
  
  
  RESULTS
  All patients had abscesses adjacent to infected sinuses. Eighteen young children had medial abscesses. Twelve of 13 were cured by initial medical treatment; 4 of 5 underwent successful initial drainage. Outcomes were not statistically different (P > .490). Seven children with nonmedial abscesses were older (P < .001) and had more complicated courses than those with medial abscess. Three of 6 children with superior orbital abscess also had intracranial abscess. Intracranial complication was more likely with superior versus medial orbital abscess (P < .01).
  
  
  CONCLUSIONS
  Medial subperiosteal orbital abscesses secondary to sinusitis in children 6 years of age and younger are highly amenable to treatment with intravenous antibiotics. Older children and children with nonmedial abscesses may have more complicated infections. Children with superior orbital abscesses are at higher risk for intracranial abscess.
