title: The role of endoscopic surgery in the treatment of nasal inverted papilloma.
abstract: The inverted papilloma is a benign neoplasm, prone to malignancy, and bearing a high rate of post-op recurrence. There is much debate in the literature concerning the issue that an endoscopic approach may offer a benefit over an external approach.
  
  
  OBJECTIVE
  Demonstrate the efficacy of an endonasal endoscopic approach in the treatment of inverted papilloma.
  
  
  METHODS
  Retrospective.
  
  
  METHODS
  Retrospective analysis of patients with inverted papilloma operated at the University Hospital--FMUSP from 1994 to 2004.
  
  
  RESULTS
  Twenty-eight patients records were studied. Nine patients (32.1%) had tumor recurrence, one being operated via the endoscopic method and eight by external approach.
  
  
  CONCLUSIONS
  Krouses staging system for inverted papillomas can facilitate both treatment planning and comparison of surgical outcomes. The use of the endoscopic approach resulted in fewer relapses than when the external one was used in cases with the same tumor staging.
  
  
  CONCLUSIONS
  The use of the endoscope in this type of surgical treatment is an important success factor in the treatment of inverted papilloma.
