| 1. A method for enlarging a natural paranasal sinus ostium that has not previously been surgically altered, the method comprising
the steps of:
inserting and advancing an elongate guide having a preset shape, a distal end and a lumen to a position within or near the
natural paranasal sinus ostium;
advancing a dilator through the lumen of the elongate guide and positioning the dilator and guide such that the dilator is
located beyond the distal end of the guide and within the natural paranasal sinus ostium; and
using the dilator to dilate the natural paranasal sinus ostium causing breakage of bone that underlies the mucosa of the natural
paranasal sinus ostium.
