Symptom assessment and archived endoscopic photographs were prospectively collected on patients who underwent frontal sinusotomy between 7\u20101\u20101999 and 12\u201031\u20102000. Subjective symptom improvements were evaluated using the SNOT\u201020 = 20\u2010item Sino\u2010Nasal Outcome Test.

The patient population was divided into two groups: 58 patients had eosinophilic CRS (ECRS), and 103 patients had CRS without eosinophils (non\u2010ECRS). The mean follow\u2010up for patients with ECRS is 61.6 months and 37.0 months for non\u2010ECRS patients. The non\u2010ECRS patients had a documented endoscopic frontal sinus patency of 90%, and the ECRS patients had an endoscopic frontal sinus patency of 85%. The overall frontal ostium patency rate for all patients was 88.0%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>Long\u2010term endoscopic confirmation of frontal ostium patency demonstrates that endoscopic frontal sinusotomy can yield high quality, durable results.
