A method of treating a constricted sinus passageway in a frontal sinus of a patient includes forming an artificial passageway into the frontal sinus of the patient with a tool. An elongate member having an inflation member thereon is inserted through the passageway. The inflation member is positioned with the constricted sinus passageway and the inflation member is expanded so as to expand at least a portion of the constricted sinus passageway.
