    Abstract: A device (1) for cleaning the external auditory canal, which device (1) includes a guide sleeve (30), with a proximal outlet portion (31) for partial insertion into the auditory canal, and an instrumentation rod (10) that can be guided axially through the guide sleeve (30). At a proximal end region, the instrumentation rod (10) has a cleaner (20) with at least one circumferentially extending cleaning element (21) which is elastically expandable in a radial direction. An internal cross section of the proximal outlet portion (31) is smaller than an external cross section of the cleaning element (21) in a radially expanded state.
