Abstract:
1. A method for locating a sinus ostium, said method comprising the steps of: inserting an endoscope through a nostril of a patient and advancing the endoscope along a longitudinal path toward a location of the sinus ostium; positioning the distal end of the endoscope such that a pathway toward the sinus ostium is within the field of view of the endoscope; inserting an illuminating guidewire through the nostril and advancing a distal end portion of the illuminating guidewire distally of a distal end of the endoscope, wherein the acts of inserting the illuminating guidewire and advancing the distal end portion are performed while maintaining the longitudinal position of the endoscope along the longitudinal path to keep the pathway toward the sinus ostium within the field of view of the endoscope; and viewing, through the endoscope, the advancement of the distal end portion of the illuminating guidewire into the field of view including the pathway toward the sinus ostium.
