An expandable nasal stent for postoperative nasal packing, comprising:
- (a) a body having outer surfaces corresponding generally to the mucosal surfaces that define a human nasal cavity;
- (b) the body being formed of a unitary layer of inherently porous foam material capable of expanding outwardly, and having a nonadherent surface for absorbing fluids from the nasal cavity without adhering to the mucosal surfaces of the nasal cavity;
- and
- (c) the body being capable of providing a nasal stent for postoperative nasal packing so as to prevent adhesions and scar formation between the mucosal surfaces.
