First Branchial Cleft Fistula Associated with External Auditory Canal Stenosis and Middle Ear Cholesteatoma

چکیده
INTRODUCTION First branchial cleft anomalies manifest with duplication of the external auditory canal. CASE REPORT This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a sinus in the helical root, may explain this feature. A canal wall down mastoidectomy with canaloplasty and wide meatoplasty was performed. The branchial cleft was excised through parotidectomy and facial nerve dissection. CONCLUSION It should be considered that canal stenosis in such cases can induce cholesteatoma formation in the auditory canal and middle ear.

We herewith report 2 patients with congenital aural stenosis who developed cholesteatoma related to the external ear canal (EEC) stenosis. One of the cases, had previously undergone craniotomy for intracranial complication of the disease, and also had postauricular fistula, whereas in the second patient it was silent and confined within the relatively enlarged stenotic ear canal in front of a r...
متن کاملFibrous Dysplasia of the Temporal Bone with External Auditory Canal Stenosis and Secondary Cholesteatoma.
Fibrous dysplasia is a slowly progressive benign fibro-osseous disease, rarely occurring in temporal bones. In these cases, most bony lesions developed from the bony part of the external auditory canals, causing otalgia, hearing impairment, otorrhea, and ear hygiene blockade and probably leading to secondary cholesteatoma. We presented the medical history of a 24-year-old woman with temporal mo...
متن کاملI. Srebniak Management of External Auditory Canal Cholesteatoma
External ear canal cholesteatoma (EAC) is a rare destructive lesion within temporal bone and may occur in 1:1000 new patients with ear diseases [1, 3]. EAC cholesteatoma was first described by Toynbee in 1850. Since that time, it had confused to keratosis obturans. First description of keratosis obturans was presented by Piepergerdes et al., in 1980 [6]. Keratosis obturans (KO) is a similar to ...
