The preoperative extent of disease was graded radiologically in each frontal sinus as total opacification, partial opacification, or mucosal thickening.

Patency was achieved after our first procedure in 107 sinusotomies. These were considered successes. Ten required revision surgery, and an additional 13 were not patent at last follow\u2010up. These 23 sinusotomies were considered failures. Among those failing our initial surgery, 19\/23 (83%) were partially or totally opacified preoperatively. In contrast, only 47\/107 (44%) in the success group contained partial or total opacification preoperatively (<jats:italic>P<\/jats:italic> = 0.003), with the majority exhibiting mucosal thickening only. Mean follow\u2010up was 8.3\u00a0months for the successes and 10.7\u00a0months for the failures (<jats:italic>P<\/jats:italic> = NS). No significant differences were observed between the success and failure groups with respect to the prevalence of asthma, aspirin sensitivity, or allergic fungal disease. Patients in the failure group, however, had a higher mean number of prior surgeries before undergoing frontal sinusotomy at our institution (1.8 vs 0.9, <jats:italic>P<\/jats:italic> =
