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 ...

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 ...

Another Etiology of Middle Ear Cholesteatoma
Archives of Otolaryngology - Head and Neck Surgery, 1971Cholesteatomata have developed away from the annulus in noninfected middle ears which have sustained perforation secondary to blast trauma. In this series of blast perforations, 12% have had epithelium located in the middle ear away from the malleus and annulus.

To establish comprehensive transcriptomic profiles of cholesteatoma perimatrix tissue and granulation tissue from chronic otitis media (COM) that did not develop cholesteatoma, which can indicate molecular pathways involved in the cholesteatoma ...

Bilateral congenital middle ear cholesteatomas
The Laryngoscope, 1984AbstractCongenital middle ear choleslcatomas remain of interest because of their relative rarity and unknown origin. A 4‐month‐old child presenting with bilateral congenital middle ear cholestcatomas forms the basis for this report. The nature of the epithelial debris found suggests an external origin.

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.

MR Imaging of Middle Ear Cholesteatomas
Journal of Computer Assisted Tomography, 1991We prospectively evaluated MR images of 14 patients who had chronic otitis media and who were suspected of having cholesteatomas on otologic examination and/or on high resolution CT. Cholesteatomas were verified in the middle ear and/or mastoid at surgery in nine patients.

Cholesteatoma of the external and middle ear in the childhood
Vestnik otorinolaringologii, 2015The objective of the present work was to enhance the effectiveness of diagnostics of cholesteatoma of the external and middle ear in the children. The study included 66 patients presenting with chronic suppurative otitis media and one child having cholesteatoma of the external auditory meatus. All the patients were examined with the use of otoendoscopy

Epidemiology and Aetiology of Middle Ear Cholesteatoma
Acta Oto-Laryngologica, 1999A total of 500 patients with cholesteatoma diagnosed and operated during 1982-91 in the region of Tampere University Hospital and Mikkeli Central Hospital in Finland were analysed retrospectively. The mean annual incidence was 9.2 per 100,000 inhabitants (range 3.7-13.9) and during the study period the annual incidence decreased significantly.

[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.
