Feasibility of In-Office Endoscopic Sinus Surgery with Balloon Sinus Dilation:

BackgroundBalloon sinus dilation (BSD) tools are increasingly used in endoscopic sinus surgery (ESS) and may cause less tissue trauma/bleeding, potentially enabling office-based ESS. We evaluate the feasibility of ESS performed in-office using BSD instrumentation.MethodsAll patients had a diagnosis with chronic rhinosinusitis. Because of symptom resolution failure post maximal medical therapy (prolonged antibiotics, corticosteroids, and other adjuvant therapies), all patients were candidates for ESS. In-office ESS using BSD tools was performed on 37 subjects at nine sites. Procedure feasibility was assessed prospectively through technical success rate, procedure tolerability, quality of life, and radiographic outcomes. Subjects were followed at 1, 4, 24, and 52 weeks.ResultsIn-office technical success by subject was 89% (33/37). There was one nonserious adverse event. In-office BSD was tolerable, with 93% (27/29) of patients reporting the procedure as tolerable or highly tolerable. Two in-office subjects ...
