[Revision intranasal sphenoethmoidectomy in recurrent nasosinusal diseases especially polyposis].

A 16 case series of intranasal revision sphenoidecthmoidectomies is presented in this study concerning 10 patients with recurrent polyposis after 245 intranasal ethmoidectomies performed between 1986 and 1990 (6.5%). The modalities of surgical decision are precisely described, pointing out the correlation between clinic and endoscopic arguments. The CT-Scan is particularly appreciated for the details of recurrence sites and the anatomical dangers along these recurrences. Comparison is established with the most recent publications in this field and the discussion is open to express the rules of this surgery. 80% of good and excellent results are obtained in this series, justifying the procedure. The causes of bad results are evocated, especially allergy and the age of polyposis.
