Background. Balloon sinuplasty is a relatively new surgical technology proposed as a less invasive way of treating chronic rhinosinusitis and frontal sinus disease. It is crucial to monitor safety and efficacy to allow informed clinical decisions and appropriate counselling of patients. There are few papers with long-term follow up.Method. Patients were selected for surgery based on symptoms of frontal pain and pressure or headache, pre-operative Sino-Nasal Outcome Test-22 scores, and computed tomography findings. All were resistant to appropriate medical therapy. Balloon sinuplasty was performed followed by a Sino-Nasal Outcome Test-22 questionnaire at two months and then two years. Results. All patients underwent successful operations with no failure of technology or technique. There were no significant complications. The average Sino-Nasal Outcome Test-22 score reduced from 46 pre-operatively (standard error: +/- 5.7, n = 9) to 23 at 2 months (standard error: +/- 7.6, n - 7). At 2 years, the average Sino-Nasal Outcome Test score was 23 (standard error: +/- 4.3, n = 6). There was an even larger lasting benefit when pain or pressure symptoms were analysed in isolation.Conclusion. This study adds to the evidence of technique safety and feasibility. The procedure resulted in a significant long-term improvement in symptoms.
