[Endoscopic treatment of iatrogenic rhino-csf fistulas: notes of surgical techniques]

The Authors describe an endoscopic technique which may be employed in closing an iatrogenic rhino-CSF fistula, today one of the most frequent complication of endonasal surgery performed in the treatment of polyposis. The technique is relatively simple for surgeons with a certain amount in expertise in endoscopic surgery of the nose. Offering the possibility of being repeated without creating great problems, the procedure also allows the surgeon to avoid much more destruction techniques carried out externally.
