Occult Cholesteatoma of the Middle Ear
ORL, 1978A clinico-pathological study of 10 cases (including histopathology) indicates that occult cholesteatoma is neither a congenital cholesteatoma nor an epidermoid cyst, originating in the attic through a melaplastic process of middle ear mucosa behind an intact tympanic membrane.

Congenital Middle Ear Cholesteatoma
Archives of Pediatrics & Adolescent Medicine, 1983A congenital aural cholesteatoma is a cystic epithelial remnant of embryonal origin found medial to the intact tympanic membrane. This entity may be identified in young children who have not had perforated eardrums and who have had no history of otitis media.

Cholesteatoma is a serious form of chronic otitis media. The aim of this paper is to present the state of the art of disease management, including recent data from the literature and the authors' derived from their Mentors' teaching, Professor Pierre Roulleau (Paris, France) and Professor Robert Charachon (Grenoble, France).

MRI of a middle ear cholesteatoma in a cat
Veterinary Radiology & Ultrasound, 2022AbstractA 9‐year‐old Maine coon cat presented with right‐sided Horner and facial nerve paralysis. Magnetic resonance imaging (MRI) showed a heterogeneously contrast‐enhancing mass occupying the right dorsolateral compartment of the tympanic cavity and extending into the ventromedial compartment, which was expanded and fluid filled.

Integrin Expression In Middle Ear Cholesteatoma
Acta Oto-Laryngologica, 1994Cholesteatoma is lined by a squamous keratinizing epithelium exhibiting most of the features of normal epidermis. In this study, we investigated by immunohistochemistry the expression of integrin adhesion molecules in primary acquired and recurrent cholesteatomas, and compared it with common epidermal cysts and normal human skin.

Middle ear cholesteatoma: An animal model
American Journal of Otolaryngology, 1985Topical otic preparations now in clinical use contain a variety of antibiotics and solvents that may produce severe inflammation if they reach the middle ear cavity. This report describes the response of the chinchilla middle ear to direct application of one such preparation that appears to act as a nonspecific irritant.

Cholesteatoma is the most severe middle ear disease. In most cases cholesteatoma results from under-aeration of the middle ear cleft. It is characterized by otorrhea and hearing loss, and may lead to severe complications, intra- and extra-cranial. There is no non-surgical treatment for cholesteatoma. Surgical treatment is the only option. Cholesteatoma

Tomographic Examination of Cholesteatomas in the Middle Ear
Acta Oto-Laryngologica, 1970A retrospective investigation of the diagnostic certainty in radiological examinations of cholesteatomas in the middle ear has been made. Through a period of six years the security has proved to be more than 90%. Small cholesteatomas which have not yet caused osseous destruction and cholesteatomas in earlier operated ears are barely accessible to ...

Lymphotoxin in Human Middle Ear Cholesteatoma
The Laryngoscope, 1991The progressive growth of epidermis appears to be a crucial factor in the pathogenesis of cholesteatoma. How this growth is encouraged is still not well understood. In the present study, lymphotoxin was found in human middle ear cholesteatoma tissues by the immunoperoxidase method using rabbit anti‐human lymphotoxin immunoglobulin G (IgG).

[Angiogenesis in cholesteatoma of the middle ear].
Acta otorrinolaringologica espanola, 1996Middle ear cholesteatoma is characterized by the presence of a keratinizing squamous epithelium with hyperproliferative features. Such growth can only be supported by abundant blood vessels. The presence and distribution of blood vessels in cholesteatoma was studied to determine the mechanisms responsible for its origin and maintenance.
