In a paper presented at the annual meeting of the American Academy of Otolaryngology—Head and Neck Surgery, San Diego, Calif, September 1990, Randy H. Lazar, MD, Ramzi T Younis, MD, and Charles W. Gross, MD, reviewed their experience with revision endoscopic sinus surgery. They found that revision surgery was required in 9.4% of 673 patients who had undergone functional endoscopic sinus surgery. The rate for pediatric patients was 7.6% (16/210), and for adults, 10.2% (47/463). Indications for the revision surgery included persistent symptoms that were not relieved by initial surgery or with 4 to 6 weeks of treatment with antibiotics and nasal steroids. These patients were also evaluated for allergy and other systemic problems prior to any revisions. Revision surgery was successful in 78% (47/63) of the cases. Restenosis of the ostia was found in nine cases and adhesions between the middle turbinate remnant and the lateral wall were noted
