Revision functional endonasal sinus surgery.

Revision functional endonasal sinus surgery (FESS) is recommended for patients whose symptoms of chronic or recurrent sinusitis persist despite primary FESS, long-term maximal medical therapy, and no sign of other abnormalities as demonstrated by computed tomography. After analyzing the charts of 673 patients who underwent primary FESS, we reviewed the 63 cases of revision surgery performed between 1986 and 1989. This retrospective analysis presents the management and outcome of 16 children (less than 16 years) and 47 adults who had revision FESS. The overall success rate of revision FESS was 78%, with no major complications, reflecting the improved management of sinus disease offered by this procedure.
