2/89. External cholesteaoma and fibrous dysplasia of temporal bone.cholesteatoma is a disease that involves almost exclusively the middle ear structures and the mastoid bone. In rare cases it involves the external auditory canal. The author would like to present case report of a patient affected by external ear canal cholesteatoma associated to fibrous dysplasia of the temporal bone. The problems related to the pathogenesis and the diagnosis of the disease are presented and discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = cholesteatoma (Clic here for more details about this article) |
3/89. Acute mastoiditis and cholesteatoma.Acute coalescent mastoiditis is an uncommon sequela of acute otitis media. It occurs principally in the well-pneumatized temporal bone. The findings of fever, pain, postauricular swelling, and otorrhea are classic. cholesteatoma, on the other hand, being associated with chronic infection, usually occurs in the sclerotic temporal bone. The signs and symptoms are isidious in nature and consist of chronic discharge and hearing loss which result from its mass, bone erosion, and secondary infection. Of 17 consecutive cases of acute mastoiditis over a six-year period, four were atypical because they were complications of chronic otitis media and cholesteatoma, yet they had the physical findings of acute mastoiditis-subperiosteal abscess and purulent otorrhea, plus radiographic evidence of mastoid coalescence.- - - - - - - - - - ranking = 0.83333333333333keywords = cholesteatoma (Clic here for more details about this article) |

5/89. Congenital cholesteatoma of the tympanic membrane.We present two cases of congenital cholesteatoma of the tympanic membrane. Congenital cholesteatoma within the tympanic membrane is a rare entity with only few cases documented. The aetiopathogenesis of this lesion is still unknown. An embryologic origin is hypothesized when cholesteatoma develops in patients without previous history of otitis as in the two cases we report. In cases with previous history of inflammatory process of the external or middle ear an acquired origin is suspected due to the proliferation of the basal cell layer of the tympanic membrane epithelium. Despite the rarity of the congenital tympanic membrane cholesteatoma, we think that its early diagnosis is of utmost importance to allow an easy removal and avoid middle ear involvement.- - - - - - - - - - ranking = 1.3333333333333keywords = cholesteatoma (Clic here for more details about this article) |
6/89. Spontaneous external auditory canal cholesteatoma complicated by rheumatoid arthritis--case report and review of the literature.A 63-year-old woman with rheumatoid arthritis sought medical assistance for dull and chronic pain in her left ear two and half years after her initial diagnostic examination. Otoscopic examination revealed that the posteroinferior wall of the bony external ear canal was eroded and that the small cavity was filled with squamous debris. The condition was diagnosed as external auditory canal cholesteatoma (EACC). The existence of EACC might suggest complications of bone disease, aging cerumen gland, or a low migratory rate of the epithelium.- - - - - - - - - - ranking = 0.83333333333333keywords = cholesteatoma (Clic here for more details about this article) |
7/89. The natural history of congenital cholesteatoma.OBJECTIVES: To describe the natural history of congenital cholesteatoma (CC) and to determine whether such a description provides clues about the origins and end points of these lesions. DESIGN: A retrospective qualitative analysis of intraoperative illustrations of 34 consecutive patients with 35 CCs (1 bilateral). SETTING: Two tertiary care children's hospitals. patients: Thirty-four children with CC, mean age, 5.6 years (range, 2-13 years). RESULTS: Congenital cholesteatoma originates generally, but not universally, in the anterior superior quadrant. The progression of growth is toward the posterior superior quadrant and attic and then into the mastoid. Contact with the ossicular chain generally results in loss of ossicular continuity and in conductive hearing loss. CONCLUSIONS: Congenital cholesteatoma appears to have a predictable trajectory of growth, starting as a small pearl in the middle ear, eventually growing to involve the ossicles and mastoid, and causing varying degrees of destruction and functional impairment. The clinical picture of a young child with otorrhea, conductive hearing loss, tympanic membrane perforation in a nontraditional location, and a mastoid filled with cholesteatoma may represent the end point in the natural history of CC, despite the fact that this type of lesion is outside the accepted definition of CC.- - - - - - - - - - ranking = 1.3333333333333keywords = cholesteatoma (Clic here for more details about this article) |
8/89. otitis media and CNS complications.Intracranial complications from otitis media can be quite devastating to the patient if an early diagnosis is not made. patients may develop meningitis, venous sinus thrombosis or cranial nerve palsies, as well as intracranial abscess. The presenting features in such cases may be subtle and include headache, nausea, vomiting, personality changes and signs of increased intracranial pressure as well as focal neurological deficits. A case of intracranial brain abscess is presented in a patient with a history of chronic otitis media with cholesteatoma. Delay in the diagnosis of intracranial complications of otitis media can lead to improper treatment with increased morbidity and mortality. The etiology and treatment of complications affecting the CNS is discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = cholesteatoma (Clic here for more details about this article) |
9/89. facial nerve paralysis secondary to chronic otitis media without cholesteatoma.Numerous papers have been written on facial nerve paralysis caused by chronic suppurative otitis media. However the authors found none documenting the results of therapy in a series of patients in whom facial nerve dysfunction was caused by chronic otitis media without cholesteatoma. Thus, there is little factual information available to help select a specific therapeutic plan for such cases. Over the past decade, the senior author has managed five cases (6 ears) of chronic suppurative otitis media without cholesteatoma in which facial paresis (4 ears) or paralysis (2 ears) developed 10 days or less before surgery. The chronic otitis media involved the mastoid and middle ear in five cases; and the mastoid, middle ear, and petrous apex in one case. Modified radical mastoidectomy was performed in four ears, tympanomastoidectomy with facial recess exposure in one ear, and complete mastoidectomy with middle cranial fossa petrous apicectomy in one ear. Five patients had complete recovery of facial nerve function (House grade I), and one patient had 90 percent recovery (House grade II). The results provide support for semi-emergent surgery in the management of chronic suppurative otitis media when facial nerve paralysis supervenes.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
10/89. Pediatric external canal cholesteatoma with extensive invasion into the mastoid cavity.cholesteatoma in the external auditory canal (EAC) is an uncommon situation, and is especially rare in pediatric patients. We report two pediatric cases of external canal cholesteatoma with extensive invasion into mastoid cavity. Both cases had otalgia and poor hearing as the initial symptoms, and received operation according to the extent of the lesions. Since external canal cholesteatoma with extensive invasion into the mastoid cavity has the propensity to involve the vertical segment of the facial nerve, extreme care should be taken when performing any procedure in this area. Through thorough pre-operative evaluation and adequate surgical procedures, good outcomes can be achieved and hearing as well as facial nerve function can be preserved.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
