  Keratosis obturans is an exceptional, occlusive disease of the external auditory meatus. Characteristically, anomalous accumulation of a wedge of desquamated keratin within the ear canal is delineated. Keratosis obturans is accompanied by accumulation of lamellar keratinaceous debris which distends and obstructs the external auditory canal with consequent occlusion and expansion of bony segment of the external auditory canal.

  Keratosis obturans as a clinical entity can be adequately diagnosed following attempted extrication of accumulated, deep-seated, desquamated keratin confined to the external auditory canal. Keratosis obturans was initially scripted by Tonynbee in 1850 and aforesaid terminology was adopted by Wreden in 1874 [1].
