title: [Application experience of endoscopic treating sinus bone fibrous dysplasia under navigation guidance].
abstract: OBJECTIVE
  Research for surgical methods and experience of sinus fibrous dysplasia treatment by auxiliary nasal endoscopy image navigation.
  
  
  METHODS
  Retrospective analysis of the records of 4 patients from March 2006 to December 2011 who were diagnosed as fibrous dysplasia of nasal sinuses, 2 male and 2 female, aged from 19 yrs to 55 yrs and average age was 38 yrs; 3 of them were destroyed of sinus floor, the other who had the bone fiber of sphenoidal sinus. By using 16 multi slice spiral CT and 3D reconstruction, the 4 cases were all treated by drill grinding abnormal fibrous tissue in the nasal sinus cavities with auxiliary nasal endoscopy image navigation, to achieve contour in the bone fiber cavities.
  
  
  RESULTS
  Lesions of 4 cases were accurately found and grinded under auxiliary nasal endoscopy image navigation. For 3 patients, headache, nasal congestion, facial discomfort and other symptoms have gradually disappeared after operation. However, one patient with sinus floor destroyed suffered facial swelling and pain 3 month after operation, with ineffective conservation treatment outcomes. After CT re-scan, it showed that there were a large number of bone residue in maxillary sinus during the re-operation. The reason was that the surgical cavity was not rinsed off which leaded to maxillary sinus congestion. With the methods of expansion of the maxillary sinus, flushing the cavity, and postoperative nasal and maxillary sinus rinse, symptoms disappeared 1 month later without recurrence.
  
  
  CONCLUSIONS
  Patients with fibrous dysplasia of nasal sinuses are treated thoroughly, securely, and effectually, by drill grinding abnormal fibrous tissue in the nasal sinus cavities with auxiliary nasal endoscopy image navigation, to achieve contour in the bone fiber cavities.
