Imaging of postoperative middle ear cholesteatoma

Clinical Radiology, 2011
Cholesteatoma 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, 1992
Mucosubstance 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, 2015
It 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.

Another Etiology of Middle Ear Cholesteatoma

Archives of Otolaryngology - Head and Neck Surgery, 1971
Cholesteatomata 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.

Bilateral congenital middle ear cholesteatomas

The Laryngoscope, 1984
AbstractCongenital 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.

MR Imaging of Middle Ear Cholesteatomas

Journal of Computer Assisted Tomography, 1991
We 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.

Epidemiology and Aetiology of Middle Ear Cholesteatoma

Acta Oto-Laryngologica, 1999
A 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.

Cholesteatoma of the external and middle ear in the childhood

Vestnik otorinolaringologii, 2015
The 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
