The treatment and prevention of chronic otorrhoea in the Northland health district.

The operation of a mobile ear clinic within the school medical service in Northland is described. The major justification for the use of a sophisticated unit lies in the opportunity which it affords for the education of children and adults on aural health. The higher costs of treatment may well be more than offset by the long-term benefits resulting from increased awareness and better understanding in our population on the causation of supporative otitis media.
