The use of cone beam computed tomography of paranasal sinuses in the investigation and management of rhinosinusitis: a national survey and our 'one-stop' rhinology clinic experience.

Objective: Cone beam computed tomography is an imaging technique that can be used for the paranasal sinuses. This study assessed how widely it is used and the impact it has on chronic rhinosinusitis management in the ENT department of one hospital.

Method: A nationwide survey was conducted to assess the use of cone beam computed tomography throughout ENT UK members. A retrospective analysis of four-year rhinology clinic data for patients presenting with chronic rhinosinusitis symptoms was subsequently performed to assess how many scans were achieved the same day and the subsequent patient management.

Results: The survey results indicated that a majority of staff do not use cone beam computed tomography to image sinuses (86.5 per cent), and this was largely because of lack of access (92 per cent). This study assessed 355 cone beam computed tomography requests. Overall, 306 cases had a cone beam computed tomography scan on the same day as their clinic appointment with the majority seen back in clinic during the same hospital attendance for the results. Overall, 97 patients were discharged on the same day.

Conclusion: This study suggested a lack of awareness and understanding of cone beam computed tomography in managing rhinosinusitis. The 'one-stop' rhinology clinic model offers benefits including reduced patient hospital attendance.
