A rhinological implant for straightening the nasal septum is fastened on both sides of a septum (S), separating left and right sides of a nasal cavity of a human nose, on the outer surface of the septum (S), in the left and the right sides of the nasal cavity. Before implantation, the implant is folded up from an initially flat blank into an implantable three-dimensional shape. The implant has a central back section which in an implanted state wraps around the free lower edge of the septum. Two side sections are provided on either side of the central back section to extend symmetrically with respect to the central back section. In the implanted state, the two side sections bear via the entire surface against the two diametrically opposed outer surfaces of the septum (S).
