Functional endoscopic sinus surgery: evaluation, surgery, and follow-up of 250 patients.

Although much has been written about the surgical technique of functional endoscopic sinus surgery, little has appeared about its long-term results. Two hundred fifty patients underwent endoscopic nasal office evaluations and subsequent functional endoscopic sinus surgery (42 unilateral + 208 bilateral = 458 procedures) for nasal polyposis and chronic sinusitis from January 1986 to June 1988. Immediate postoperative data indicated that 8.3% developed minor complications and 0.7% developed major complications. Two hundred twenty-one patients were available for long-term follow-up at 12 to 42 months (mean = 17 months) with success rates of 89.7% for relief of sinonasal polyposis and 80.2% for relief of chronic sinusitis.
