Abstract
Tympanokeratoma is an otic affliction, frequently known as cholesteatoma or epidermoid cyst, being characterized as an non-neoplastic mass formation at the level of the middle ear. This mass is compose of keratin debris covered with keratinizing squamous epithelium, with multiple layers. It presents a continuous growth and determines the destruction of the tympanic bulla wall. Imaging examination reveals the presence of a soft tissue-like material in the middle ear and with different grades of affliction of the tympanic bulla wall integrity. The imaging examination helps to identify the tympanokeratoma, but the final diagnosis is establish by histopathological examination.
