We introduce our IGS reference frame for easy and rapid registration. we produced dentally affixed reference frame tailored for each patient. This reference frame is detachable and has both fiducial markers and reference markers. So, by taking patient's CT scans with this reference frame, we can finish the registration without patient, before surgery. The only preparation for IGS in the operating room is to attach the reference frame on the patient again. This dentally affixed reference frame is suitable for image guided ENT surgery where invasive or time-consuming registration method is unmatched.
