title: Orbital subperiosteal hematoma associated with sinus infection.
abstract: OBJECTIVE
  There are few reports of orbital subperiosteal hematomas as a result of sinusitis complications. The present study reports on 2 such cases and presents a literature review regarding this condition.
  
  
  METHODS
  We report 2 cases of orbital subperiosteal hematoma, and reviewed previous literature reports.
  
  
  RESULTS
  Including the 2 current patients, 11 cases of orbital subperiosteal hematoma involving sinusitis appear in the literature. The current cases involved 2 older females presenting with proptosis. One had frontal sinusitis and the other a postoperative frontoethmoid mucocele. Both patients underwent a superior orbitotomy and sinus surgery, which resolved the orbital symptoms.
  
  
  CONCLUSIONS
  Orbital subperiosteal hematomas can develop associated with sinus infection. Such a condition should be treated as a sinusitis complication and the associated sinus infection must be treated concomitantly.
