Keratosis obturans – http://id.who.int/icd/entity/634950675

A localised accumulation of desquamated keratin in the external auditory canal, thought to be due to a defect in normal epithelial migration. It is usually bilateral and typically presents at a younger age than external auditory canal cholesteatoma. There is conductive hearing loss, sometimes with otalgia.
