Objective To determine the efficacy of endoscopic surgery for chronic frontal sinusitis.
Design A prospective analysis of established measures of clinical outcome (Chronic Sinusitis Survey and Short Form 36) that was administered to patients before frontal sinus surgery and at intervals of 3 months, 6 months, and 1 year after surgery.
Interventions For limited disease, the frontal recess was opened and the frontal ostium probed or enlarged. For more severe cases, a drill was used to resect the frontal sinus floor and interfrontal septum.
Setting Private and institutional-based practices at an academic medical center.
Subjects Eighty-seven patients who underwent endoscopic surgery for frontal sinusitis, including 24 patients with severe disease who underwent a frontal sinus drillout procedure.
Main Outcome Measures Scores on the Chronic Sinusitis Survey, Short Form 36, and surgical revision rate.
Results Significant improvement in facial pain, nasal drainage, and congestion was observed 1 year after surgery (P<.01). Medication use was also significantly reduced during this period (P<.01). Quality-of-life measures showed greatest improvement in the domain of social functioning (P<.05). Three (12.5%) of 24 patients who underwent a frontal sinus drillout procedure did not respond to surgery secondary to restenosis of the frontal ostium.
Conclusions Although the long-term results of endoscopic surgery for frontal sinusitis are unknown, this approach appears to be effective for most patients and may provide a reasonable alternative to frontal sinus obliteration surgery in selected cases.
