title: [Aspergillosis of the paranasal sinus and environmental factors].
abstract: Paranasal sinus aspergilloma is a non-invasive form of Aspergillus infection being encountered more often during the last decade.
  
  
  METHODS
  A survey of specialists in France was carried out in 1998 to investigate the role of environment in the pathogenesis of the disease.
  
  
  RESULTS
  A total of 402 patients' reports were reviewed, most of which involved unilaterally the maxillary sinus. We observed a predominance of women (sex ratio 1.9) and dental care in the past of 338/402 patients (84.1%). Environmental exposure that could interfere with aspergilloma were found in only 136 patients (33.8%) and in 21/48 (43.8%) patients who had had no dental care.
  
  
  CONCLUSIONS
  Aspergilloma of the paranasal sinus has probably a multifactorial etiology, we could not point out environmental factors in this survey.
