2/183. External acoustic meatus cholesteatoma.cholesteatoma is a condition usually affecting the middle ear and mastoid, but in certain cases it can be found in the external ear canal. It usually affects elderly people and presents with chronic otorrhoea and dull otalgia. The disease can progress to extensive mastoid destruction. Small lesions can be treated with regular microscopic debridement in out-patients while larger lesions require surgery to eradicate the cholesteatoma sac. We present 2 cases of external ear cholesteatoma to add to the less than 50 cases reported to date.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
3/183. Congenital cholesteatoma and malformations of the facial nerve: rare manifestations of the BOR syndrome.We describe a 14-month-old girl with unilateral congenital cholesteatoma and anomalies of the facial nerve in addition to the more common branchial arch, otic, and renal malformations comprising the branchio-oto-renal (BOR) syndrome. Her mother also has the BOR syndrome and unilateral duplication of the facial nerve. This is the first study of a BOR patient with congenital cholesteatoma and the second family in which cholesteatoma and anomalies of the facial nerve are described in patients with the BO/BOR syndrome. We review the congenital cholesteatoma literature and discuss hypotheses for the pathogenesis of this entity in light of this new report.- - - - - - - - - - ranking = 1.3333333333333keywords = cholesteatoma (Clic here for more details about this article) |
4/183. Schwannoma of the chorda tympani nerve.We report a case of schwannoma of the chorda tympani. This is a very rare benign tumour and only five other cases have been found in the literature. This is the first case to mimic a cholesteatoma presenting as a pearly tumour in the postero-superior segment of the drum with aural discharge and conductive deafness. diagnosis is usually by biopsy and treatment is surgical with preservation of facial and auditory function. A summary of the other presentations of this tumour together with a review of the histopathology of the disease is presented.- - - - - - - - - - ranking = 0.16666666666667keywords = cholesteatoma (Clic here for more details about this article) |
5/183. Congenital maxillary sinus cholesteatoma.cholesteatoma of the paranasal sinuses is a rare condition. The purpose of this paper is to present a child with a congenital maxillary sinus cholesteatoma. An 18-month-old girl presented with a 4-week history of right cheek and intraoral swelling. Examination revealed a smooth swelling of the right hard palate in association with the facial swelling in the maxillary region. An inferior meatal antrostomy revealed pultaceous debris in the right maxillary antrum and biopsy confirmed a maxillary sinus cholesteatoma. The inferior meatal antrostomy was enlarged to allow exteriorisation of the disease. recurrence of the disease has not presented on follow-up. An exteriorisation procedure as performed, in child of this age, allows normal facial growth. If recurrence develops then further treatment may be instituted in a more mature facial skeleton.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
6/183. Positional vertigo as a first symptom of a cerebellopontine angle cholesteatoma: case report.We report a case of a cerebellopontine angle cholesteatoma whose initial sign was benign paroxysmal positional vertigo (BPPV). Positional vertigo caused by a central pathology is extremely rare and is usually accompanied by other suspicious features. In this case, there were no additional neurotologic symptoms or signs. The only abnormalities were seen on Dix-Hallpike testing, but because they were not consistent with a diagnosis of BPPV, the decision was made to proceed to imaging. Diagnostic rigor is required when evaluating positional vertigo, as with all symptoms of imbalance, if such cases are not to be overlooked.- - - - - - - - - - ranking = 0.83333333333333keywords = cholesteatoma (Clic here for more details about this article) |
7/183. Migration of intradural epidermoid matrix: embryologic implications.The migratory behavior of acquired cholesteatoma matrices (those arising from the tympanic membrane) has been described previously. This tissue is derived embryologically from the first branchial groove and represents the only migratory epithelium arising from the branchial groove system. If the matrix from a cerebellopontine angle (CPA) epidermoid tumor exhibits migratory behavior similar to that of acquired cholesteatomas, a first branchial groove site of origin for CPA epidermoids would be supported. Intradural CPA epidermoid cells were grown in alpha-minimum essential medium. The cultures were examined daily, and cell mass migration rates were measured. It was observed that intradural epidermoid tumor matrix harvested from the CPA exhibited migration in vitro. Its migratory properties were indistinguishable from those of acquired cholesteatomas, which are embryologically derived from the first branchial groove. These data support the theory that purely intradural epidermoids are derived from cells of the first branchial groove.- - - - - - - - - - ranking = 0.5keywords = cholesteatoma (Clic here for more details about this article) |
8/183. External canal cholesteatoma.OBJECTIVE: External canal cholesteatoma (ECC) may develop spontaneously or as a consequence of infection, trauma, or surgery. There is little information on the relative incidence of ECC according to cause. An analysis of cases was conducted to compare the clinical, surgical, and radiographic features of different types of ECC. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. patients: All patients with cholesteatoma of the external auditory canal. INTERVENTION: Treatment was variable, ranging from local debridement and topical antibiotics to tympanomastoidectomy. MAIN OUTCOME MEASURE: Assignment of cause is based on the combination of clinical history, physical examination, and radiographic appearance. RESULTS: A total of 39 patients were reviewed, 5 of them with bilateral lesions. The cause was iatrogenic in 15, spontaneous in 13, trauma in 6, congenital in 2, postinflammatory in 2, and postobstructive in 1. Surgery was performed in 25 cases. Successful results were obtained in most patients. CONCLUSION: The cause of an ECC is determined on the basis of clinical features and radiographic appearance. The treatment plan is influenced by the cause of the ECC. Surgery is frequently necessary in congenital, posttraumatic, postobstructive, and iatrogenic ECC. Spontaneous lesions are usually controlled with office debridement.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
9/183. 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) |
