This is a histological and biochemical study of cholesterol in the middle ear in various chronic otitis media syndromes of 22 cholesteatomatous temporal bones and 52 bioptic specimens. Only three of the temporal bones and 11 surgical specimens showed cholesterol crystals, all of which were in the granulation tissue surrounding the cholesteatoma and ...

'Cholesteatoma' of the orbit is a variant of pseudotumor histologically characterized by masses of cholesterol crystals. We propose the term "epidermoid or true cholesteatoma" for lesions containing epithelial elements and refer to those nonepithelium-containing pseudotumors as "cholesterol granulomas." Important clinical features distinguish between ...

The special kind of keratoma found in the temporal bone, which has been called cholesteatoma by our otologic forefathers, was an unsolved problem in Virchow's time. It still is. I feel that a careful scrutiny of some classic words concerning cholesteatoma is in order.

Acquired cholesteatoma is a disease of the posterior superior part of the middle ear cleft that may arise from the external epithelium of the tympanic membrane. Three distinct epithelial zones of differing thicknesses characterize the development of this latter epithelium, and the thickness differences and their distribution in the eardrum and deep ...

Acquired cholesteatoma of the middle ear is usually diagnosed by otoscopy and treated by exploratory surgery. The role of imaging for such cases is as controversial now as it was 10 years ago, despite significant improvements in spatial and contrast resolution resulting from computerised sectional imaging.

Congenital cholesteatomas have historically been considered a rare disorder. However, a review of the literature reveals an incidence ranging from 4 to 24%, and these values are probably underestimated. This article summarizes the general diagnostic criteria of congenital cholesteatomas, their usual presenting symptoms and findings, perioperative ...

Aural cholesteatoma Is a disease entity well known to the otologic community. Complications of cholesteatoma, although uncommon, are not usually life threatening. We present two cases in which a unique and hitherto unreported pathway of spread of a cholesteatoma is noted.

Cholesteatoma in children falls into two main categories: congenital and acquired. Though they present in different ways, both are potentially destructive lesions that are managed surgically. The goals of treatment are to eradicate keratinizing squamous epithelium from the temporal bone and to preserve or restore hearing.

Congenital cholesteatoma of the temporal bone may be encountered by the otologist in the cerebellopontine angle, petrous bone, or middle ear cleft; the latter occurrence seems most likely. The etiology, epidemiologic factors, location of intracranial occurrence, clinical features, methods of diagnosis, differential diagnosis, gross and microscopic ...

Although the effective control of acute otitis media has reduced the number of cases of acute coalescent mastoiditis, the incidence of chronic mastoiditis caused by cholesteatoma has not been decreased with antibiotic usage. Surgery is required for management. This article outlines preoperative management of patients with cholesteatoma and the approach
