Devices and methods for creating a breathing passage and/or for maintaining a position of a septum. An exemplary device includes a base member, a first side member extending upward away from a first edge of the base member and being configured to contact a septum of a nasal cavity, and a second side member extending upward away from a second edge of the base member and being configured to contact a turbinate. The first and/or second side members are made of a flexible material. An exemplary method includes inserting a septum support into one side of a nasal cavity for creating a breathing passage, placing a first side member and a second side member of the septum support into contact with a septum and a turbinate, respectively. The first and second side members are biased away from one another such that pressure is applied to the septum.
