Abstract

A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. An elongate member is inserted through the passageway, the elongate member having an inflation member such as a balloon disposed thereon. The inflation member is positioned within the constricted passageway. The inflation member is expanded so as to expand at least a portion of the constricted sinus passageway.
