Many of our new patients are nervous about undergoing sinus examination with a nasal endoscope. Your safety and comfort are our top priorities. Prior to your nasal endoscope exam, you will be sprayed with medication that will decongest and numb your nasal passages. The endoscope will allow your provider to look deeper into your sinuses than with traditional instruments. You will be able to view your exam at the same time.
Many of our new or return patients will need a CT scan of their sinuses at their visit. For your safety and convenience, we offer low-dose CT imaging at many of our offices. Low dose CT scanners such as the Xoran MiniCat CT system pictured here allow a 10-50 fold reduction in effective radiation dose compared to conventional CT imaging of the sinuses. A CT scan is a common diagnostic tool in our practice and our imaging protocols ensure that this procedure is both safe and convenient for our patients.
