CONGENITAL AURAL ATRESIA WITH CHOLESTEATOMA-A CASE REPORT

Abstract

The external auditory canal opens medial to lateral in embryonal development. It is obvious that a developmental arrest anywhere during this stage would produce an absence or discontinuity of the canal, that is, congenital atretic ear. Microtia is usually associated with an atretic meatus, and it may involve the possibility of epithelial cyst or cholesteatoma1. The diagnosis can usually be made by the finding of tender swelling in the deformed auricle or its surroundings. On occasions, it may become necessary to distinguish these conditions from secondary infection of an epidermal cyst on the auricular surface. Several recurrent painful swellings on the deformed auricle in spite of               conservative treatment indicate the need for routine otologic radiographs. A 21 year female reported to our ENT                 department with right ear microtia with complaints of ear  discharge and post auricular ear pain for past 1 month and right facial nerve palsy from birth, for which modified radical mastoidectomy with type 3 tympanoplasty done.
