An insert (1) for treating human or animal body cavities, in particular ear cavities, comprises an operating element (2) which is located at one end of the insert intended to be introduced into the cavity and to come into contact with the internal walls of the latter, and is expandable from a radially compressed configuration, in which it may be introduced into the cavity without substantial interference with the internal walls, to a radially expanded configuration having a substantially larger cross-section relative to the compressed configuration, in which radially expanded configuration the operating element (2) is pressed against the internal walls of the cavity.
