In-Office Sinus Dilation Now Available!

Sinus dilation is a minimally invasive option that can be performed by Dr. Chilson right in the office. The procedure utilizes small balloons placed in key places in the nose and sinus, which are then dilated to expand the sinus pathways. It may be an effective, lasting option for some patients whose symptoms do not resolve with medication.
