Balloon Catheter Dilation of the Frontal Sinus Ostium.

The decision to operate on the frontal sinus is based on persistent symptoms that have been refractory to appropriate medical therapy with associated radiographic evidence of disease by computed tomography. There is currently no evidence to support operating on radiographically negative frontal sinuses, regardless of the availability of technology or site of service options. There are many surgical procedures as well as a variety of different technologies available for the treatment of symptomatic, medically refractory frontal sinus disease. Balloon catheter dilation can be performed safely in an office setting with outcomes comparable to those in traditional operating room settings.
