Abstract
Generally, abnormal pressures in the sinus cavity can have physiological effects due to stimulation or injury of various nerves that are in proximity to the sinus, including increased or decreased pressure on the nerves as well as extrusion of the nerves into the sinus cavities due to bony dehiscence. Methods and devices for alleviating disorders associated with the sinus cavities are described. Embodiments herein include diagnosing these disorders by occluding or restricting the sinus ostium and assessing the physiological effects caused by the occlusion/restriction and treating these disorders by navigating/directing a dilating device to the sinus ostium and dilating the sinus ostium. Other embodiments are directed to devices for maintaining the ostial opening.
