Tuberculosis of middle ear cleft.

ABSTRACT

Three cases of tuberculosis of middle ear cleft who presented with ear discharge, postaurale swelling post-aural fistula and facial nerve palsy in one case are reported. Audiometry showed conductive deafness in two cases and sensorineural deafness in one case. Roentgenograms revealed bony erosion of the mastoid bone in two cases and coalescence of mastoid air cells in one case. Modified radical mastoidectomy was done in all the three cases and histopathology of tissue removed on operation revealed tuberculosis. All the symptoms except facial nerve palsy improved and post-aural wound healed completely with anti-tubercular therapy. Early recognition and specific therapy may avoid these complications like fistula formation, facial nerve palsy and deafness and may well reduce the need for surgical procedure.
