title: [Exophthalmos arising from paranasal sinuses].
abstract: BACKGROUND
  Proptosis due to intraorbital process is frequent and secondary to various aetiologies. Its findings in ENT practice is the sign of a serious complication. The purpose of this study is to review a series of patients who presented an exophtalmy.
  
  
  METHODS
  We conducted a retrospective analysis of 15 patients with exophthalmos complicating a rhinosinusal benign disease, diagnosed and treated in our department between January 2003 and December 2010. As their management is different, we excluded all cases of orbital cellulitis.
  
  
  RESULTS
  Average age of presentation was 38 years, without sex predominance. Exophthalmos was unilateral, non axial and irreductible in all cases. The average duration of symptoms installation was 18 months. The most common aetiology was fronto-ethmoidal osteomas (9 cases), followed by fronto-ethmoidal mucoceles (5 cases) and spheno-orbito-frontal fibrous dysplasia (1 case). The functional prognosis of the affected eye depended on the aetiology and the degree of ocular injury.
  
  
  CONCLUSIONS
  In our experience, sinusal causes of exophthalmos comprise osteomas and ethmoidal mucoceles. Medical history, clinical and radiological data as provide the diagnostic. In case of benign tumours, surgery is the curative treatment.
