Ferlito A, Devaney KO, Rinaldo A, et al. Ear cholesteatoma versus cholesterol granuloma. Ann Otol Rhinol Laryngol 1997;106:79–85 This is an excellent histopathology-based review (no images) that defines and differentiates these two entities. Very interesting information. Authors reiterate that cholesteatoma is a misnomer: it is not a neoplasm (-oma), there are no cholesterol crystals (chole-), ...

Congenital cholesteatoma may originate at various sites in the temporal bone. For example, in the petrous apex, the cerebellopontine angle, the middle ear cavity, the mastoid process or the external auditory canal. The least common site being the mastoid process. We present two cases of congenital cholesteatoma of the mastoid process, each presenting with different symptoms and at different age...

The sequence of eustachian tube (ET) dysfunction leading to negative pressure and progressive tympanic membrane (TM) retraction has long been implicated as one of the most plausible hypotheses in the pathogenesis of acquired cholesteatoma.1,2 The objective of this case report is to notify on a patient with a pars tensa cholesteatoma, whose development was closely related to an aberrant course o...

DWI is a useful technique for the evaluation of cholesteatomas. It can be used to detect them when the physical examination is difficult and CT findings are equivocal, and it is especially useful in the evaluation of recurrent cholesteatoma. Initial DWI techniques only detected larger cholesteatomas, >5 mm, due to limitations of section thickness and prominent skull base artifacts. Newer techni...

This article presents accounts of two patients with cholesteatoma of the tympanic part of the temporal bone, located immediately lateral to the tympanic annulus (and with an intact tympanic membrane). The lesions were located deep in the anterior and inferior walls of the canal, especially in the vaginal process of the tympanic part. These more severe cases required surgical correction (removal...

Cholesteatoma of the External Auditory Canal Cholesteatoma of (CEAC) is defined as an accumulation of keratin that produces periosteitis and bone erosion of its walls [1-4] (usually in their lower portions or above) the eardrum and middle ear sometimes not affected [5]. It differs from the keratosis obturans because it produces a circumferential widening of the EAC, chronic Otorrhea and pain, b...

OBJECTIVE To present the experience in the operative management of labyrinthine fistula caused by cholesteatoma. METHODS The clinical charts of 16 patients who underwent surgical procedures for cholesteatoma complicated by labyrinthine fistula between 2003 and 2008 were reviewed retrospectively. In this period, 108 ears were operated for cholesteatoma. In each patient, the site and size of th...

Abstract Background Making the diagnosis of congenital cholesteatoma in adult patients still pose a challenge even among experienced otologists. Case presentation We are discussing case young who was initially treated as Bell palsy different center. Two years later, she presented with marked unilateral hearing loss addition to her ipsilateral non-resolving facial asymmetry. Conclusions Consider...

Introduction and objective: Tympanic Membrane Cholesteatoma (TMC) is a rare pathology of unknown etiology which occurs more frequently in pediatric population, being the presentation adults exceptional. Resection lesion usually surgical treatment through transcanal approach.

Among 30 children with cholesteatoma undergoing surgery at the Bicetre Hospital between 1985 and 1990, 8 had intact tympanic membranes. Since this represents a larger portion of the patient population than would be expected from previously published data, we under-look a critical analysis of the clinical findings. Among these 8 cases, 2 corresponded to the criteria of congenital cholesteatoma w...
