A pressure equalizing assembly (10) comprises a face mask (12) having a seal (20) disposed about the outer periphery which is specifically dimensioned and configured to surround the nose and nostrils of the user in an outwardly spaced relation. The seal effectively isolates the nasal cavity and nasopharynx when the user swallow and defines direct fluid communication with a vacuum chamber and a pressure regulating assembly (33) serving to create an initial negative pressure within the nasal cavity and nasopharynx. Fluid in the form of mucous, liquid and/or air is transferred from the sinus cavities which may define a zone of relative high pressure such that the pressure is effectively regulated between the sinus cavities, middle ear, nasal cavities and nasopharynx through the selective manipulation of the pressure regulating assembly thereby providing immediate relief from sinus pain while helping to relieve middle ear pressure and associated symptoms. |
