Introduction. Intracranial extension of cholesteatoma is rare. This may occur de novo or recur some time later either contiguous with or separate to the site of the original cholesteatoma. Presentation of Case. A 63-year-old female presented to a tertiary referral hospital with a fluctuating level of consciousness, fever, headache, and right-sided otorrhoea, progressing over several days. Her p...

Cholesteatoma is a destructive lesion involving the temporal bone, which may induce severe complications due to its expansion and erosion of adjacent structures. Bacterial biofilm plays a crucial role in the pathogenesis of many otolaryngologic inflammatory/infectious chronic diseases. In this pilot study, we investigated, by means of cultural examination and with scanning electron microscope, ...

Diagnosis of acquired middle ear cholesteatoma on MR imaging is mostly done on late postgadolinium T1-weighted MR images and/or echo-planar (EPI) diffusion-weighted (DWI) MR images. We describe the appearance of a case of a complicated attical middle ear cholesteatoma on single-shot (SS) turbo spin-echo (TSE) DWI compared with EPI-DWI. This case suggests a higher reliability of SS TSE-DWI in th...

Congenital cholesteatomas are epithelial lesions that present as an epithelial pearl behind an intact eardrum. Congenital and acquired cholesteatomas progress quite differently from each other and progress patterns can provide clues about the unique origin and pathogenesis of the abnormality. However, the exact pathogenic mechanisms by which cholesteatomas develop remain unknown. In this study,...

BACKGROUND Aural cholesteatoma is an epidermal cyst of the middle ear or mastoid that can be eradicated only by surgical resection. It is usually managed with radical or modified radical mastoidectomy. Clinical diagnosis of recurrent cholesteatoma in a closed postoperative cavity is difficult. Thus, the accepted protocol in most otologic centers for suspected recurrence consists of second-look ...

INTRODUCTION Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease. OBJECTIVE This study aimed to determine the prevalence of cholesteatoma in patients with chron...

BACKGROUND AND PURPOSE Non-EPI DWI is a promising alternative to second-look surgery for the detection of residual and/or recurrent cholesteatoma. We evaluated the diagnostic accuracy, expressed as a positive predictive value, of MR imaging for the detection of residual and/or recurrent cholesteatoma in our hospital. MATERIALS AND METHODS Fifty-six MR imaging studies were performed from 2005 ...

Authors debate about cholesteatomas, from the first time this word was employed, by Muller, in 1838, until the recent updates. They dissert about its definition, etiology and pathology and present basic concepts about its biology. They also make a wide review about pediatric cholesteatoma, its epidemiology and biology, and compare it with adult cholesteatoma. Finally, they describe some article...

Background: our research discovered that cholesteatoma development was more prevalent in those who have a central perforation and persistent otitis media. Physical exams meticulous reviews of medical records were performed on 100 people had chronic media with perforation. A total four persons, or 4% cases, cholesteatoma. Therefore, it would appear are prone to develop cholesteatoma, necessitati...

Mastoiditis is a common complication of acute otitis media. It in younger age compared to adulthood. occurs when an media infection spread directly involve the bone mastoid air cell causing osteitis. Cholesteatoma can contribute development mastoiditis. This typically leads breakdown some fine bony trabeculae cells producing coalescent mastoiditis with emphyema antrum. The treatment for intrave...
