Sinus Home... Welcome to my virtual sinus laboratory. If you follow the 3D Sinus Pictures links on the left from top to bottom, you will learn about the inside of your nose and sinuses. These images are from the virtual reality environment that I have created. Its purpose is to help explain sinus and nasal topics to patients, primary care physicians, and specialists. In my lectures, participants wear polarized glasses to decode the 3D images from special projectors, giving a true 3D stereoscopic experience. I hope you enjoy and learn. If you have 3D glasses or hardware, you can view these images in true 3D here. 1999 Peter Casano, M.D .
