1/249. Multifocal cholesteatoma of the external auditory canal following blast injury.

    Posttraumatic cholesteatoma of the external auditory canal is a rare condition that may present years after the original injury. A unique case of multifocal cholesteatoma of the external auditory canal following blast injury is presented and discussed. ( info)

2/249. 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. ( info)

3/249. 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. ( info)

4/249. Beware of dogs licking ears.

    A patient with right-sided chronic purulent otorrhoea developed meningitis due to pasteurella multocida transmitted by a dog that frequently licked his ear. We suggest that patients with a perforated tympanic membrane should avoid being licked on their ears by animals. ( info)

5/249. Cochleo-vestibular manifestations of jugular foramen pathologies.

    patients presenting pathologies of the jugular foramen are presented, for whom the main symptoms are of cochleo-vestibular nature. A classification of the various pathologies is attempted, the anatomy reviewed and hypotheses capable of producing the symptom elaborated. ( info)

6/249. 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. ( info)

7/249. 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.

8/249. Radiodiagnosis of intracranial pearly tumours with particular reference to the value of computer tomography.

    The radiological appearances of 22 histologically proven epidermoid and dermoid tumours occurring in four sites are presented - (1) the petrous apex and cerebellopontine angle, (2) the suprasellar region, (3) the cerebral hemispheres and (4) the cerebellum and 4th ventricle. Pathognomonic radiological changes are only uncommonly demonstrated by conventional neuroradiological techniques. Computer assisted tomography employing an EMI scanner has demonstrated diagnostic appearances. The availability of detailed density changes occurring within the tumours together with additional intracranial information makes computer tomography the investigation of choice. ( info)

9/249. 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. ( info)

10/249. 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. ( info)
