Balloon catheter sinusotomy: one-year follow-up--outcomes and role in functional endoscopic sinus surgery.

The primary objective was to assess the long-term effectiveness of balloon catheter sinusotomy.


Patients who had sinus ostia dilated with balloon catheters were prospectively evaluated 1 year after surgery with nasal endoscopy, a CT scan, and the Sino-Nasal Outcome Test (SNOT-20).


Sixty-six patients (202 sinuses) were examined. One hundred seventy-two of 202 sinus ostia (85%) were endoscopically patent, 1 percent (2/202) were nonpatent, and ostial patency could not be determined by endoscopy in 28 of 202 (14%). In these "indeterminate" sinuses, the CT scans were normal in 13, implying functional patency in 91.6 percent of sinuses (185/202). Sinus CT scan scores were 1.95 at 1 year versus 8.89 at baseline (P < 0.001), and 1-year SNOT-20 scores (0.91) were significantly improved from baseline (2.14, P < 0.0001).


Balloon catheter sinusotomy results were durable over the study period, showing long-term effectiveness.
