A Cure for PAINS? A Novel Approach to Management of Proton-Associated Internal Nasal Valve Stenosis.

Acquired internal nasal stenosis as a result of radiotherapy to the sinonasal region can be highly distressing for patients and difficult to correct surgically. We describe our experience using a controlled radial expansion balloon to dilate the area of stenosis, followed by stenting to the region. We achieved excellent results in 3 patients using this technique, with improvement in subjective nasal airflow across 100% of stenoses and complete resolution in 83%. This technique offers a simple and low-morbidity option for the management of acquired anterior nasal stenosis and is of particular value in cases of irradiation, which has the potential for poor tissue healing.
