Your Visit to Cal Sinus

During your visit to Cal Sinus, you will undergo a sinus examination with a nasal endoscope. The endoscope will allow your provider to look deeper into your sinuses than with traditional instruments. Your safety and comfort are our top priorities; prior to your nasal endoscopy, you will be sprayed with medication that will decongest and numb your nasal passages. Additionally, you'll be able to view your exam in real-time with personal video glasses.

Low Dose CT Scan

A CT scan is a common diagnostic tool used to get an inside view of your sinuses. For your safety and convenience, we offer low-dose CT imaging at many of our locations. The Xoran MiniCAT CT pictured above provides a 10-50 fold reduction in effective radiation compared to conventional CT imaging and ensures the safety and comfort of our patients.
