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.

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.

Annales d'oto-laryngologie et de chirurgie cervico faciale : bulletin de la Societe d'oto-laryngologie des hopitaux de Paris, 2006
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).

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).

Imaging of postoperative middle ear cholesteatoma
Clinical Radiology, 2011Cholesteatoma is often treated surgically using canal wall-preserving techniques. Clinical and otoscopic diagnosis of residual or recurrent disease after this form of surgery is unreliable and thus radiological imaging is often used prior to mandatory "second-look" surgery.

Sialomucin in Middle Ear Cholesteatoma Perimatrix
Acta Oto-Laryngologica, 1992Mucosubstance histochemistry of human middle ear cholesteatoma revealed that sialomucins are abundant and sulfomucins present in small amounts in the glandlike structures of the cholesteatoma perimatrix. Based on the study, various glycoproteins were injected into the dermis of the external ear canal and infiltrated into the tympanic membranes of ...

Osteoclasts are not activated in middle ear cholesteatoma
Journal of Bone and Mineral Metabolism, 2015It is unclear whether osteoclasts are present and activated in cholesteatomas. We explored the expression of messenger RNA (mRNA) for osteoclast biomarkers and regulating factors in middle ear cholesteatomas to elucidate the level of osteoclast activity in this disease.
