1. A method for measuring the size of a paranasal sinus ostium of a patient, the method comprising the steps of:
- (a) inserting a distal end portion of a paranasal sinus ostium measuring device internally into a patient, locating the paranasal sinus ostium to be measured with the distal end portion of the paranasal sinus ostium measuring device;
(b) positioning the distal end portion of the paranasal sinus ostium measuring device within the patient to enable the target paranasal sinus ostium to be measured;
(c) determining the paranasal sinus ostium size of the targeted paranasal sinus ostium by the paranasal sinus ostium measuring device, wherein the act of determining the paranasal sinus ostium size comprises determining the diameter of the paranasal sinus ostium by identifying a diameter of a portion of the distal end portion of the paranasal sinus ostium measuring device which contacts or closely approximates the walls of the paranasal sinus ostium;
(d) withdrawing the paranasal sinus ostium measuring device from the targeted paranasal sinus ostium;
(e) subsequent to withdrawing the paranasal sinus ostium measuring device, selecting a dilator device based upon the determined size of the targeted paranasal sinus ostium; and
(f) dilating the targeted paranasal sinus ostium with the selected dilator device, wherein the act of dilating comprises remodeling bony structure that surrounds or is adjacent to the targeted paranasal sinus ostium.

Abstract
Devices and methods for accurately determining the size of an ostium of a patient and in particular sinus ostium. Methods for measuring a target ostium comprise inserting the distal end portion of an ostium measuring device into a patient, locating the target ostium with the measuring device, positioning the distal end portion of the measuring device appropriately adjacent to or into the target ostium and determining the diameter(s) of the target ostium by comparing the length, diameter and/or the circumference of the portion of the distal end portion of the measuring device adjacent to or within the target ostium.
