[Inverted nasosinusal papilloma. 11 cases and bibliographic revision].
BACKGROUND
We present the cases registred from 1998 to 2003 and a revision of the bibliography.


METHODS
In the section of Rhinology of a second level Hospital 11 patients affected by inverted papilloma type 1 of the OMS classification were diagnosed aged between 40 and 79, 9 men and 2 women. They were explored through endoscopy and biopsy and the exeresis of the lesion was done by endoscopic polipectomy with microdebrider (PEM).


RESULTS
All the cases at stage I, II and III of the Krouse classification. Treated by CEN, 6 by mixed endonasal approach and through the canine fossa 4 by nasal approach only and 1 by Caldwell-Luc approach. The follow-up was done between 9 to 64 months and there was a recidive who was operated by open surgery and no one malignant transformation was seen.


CONCLUSIONS
We coment the aspects related to etiology, the symptons and the surgical technics.


CONCLUSIONS
We propose to stage the tumor and the realisation of a PEM with topic anesthesia with deep biopsies in all unilateral poly formations to avoid a retarded diagnosis and to be able to apply endoscopic technics.
