Systems and related methods treat snoring and other sleep related disorders by stabilizing the position of a tongue in an oral cavity. The systems and methods employ an operative element sized and configured to be fitted to less mobile tissue in the oral cavity. The operative element is further constructed and arranged to interact with a tongue in the airway to stabilize a preferred tissue orientation. The operative element can comprise a suction source sized and configured to draw more mobile tongue tissue toward the suction source. The operative element can comprise a magnetic source sized and configured to magnetically attract material fitted to more mobile tongue tissue in the airway.
