A Rare Presentation Of Osteoma Of External Auditory Canal

Osteoma of external auditory canal is a rare, slow growing benign tumor with an estimated incidence of 0.05%. Osteoma in external auditory canal is usually asymptomatic but can cause symptoms such as conductive hearing loss, aural fullness in large osteoma occluding the external auditory canal. Osteoma is diagnosed by clinical presentation, radiological and histological investigations. We present a case report of 28year old female with left external auditory canal osteoma with dehiscent facial ridge and complete tympanic membrane and malleus erosion

Osteoma of external auditory canal associated with external auditory canal cholesteatoma and exuberant granulation tissue in mastoid air cell system: a rare association.

Osteoma of EAC is a rare tumour. Cholesteatoma of EAC associated with osteoma is consequence of osteoma of EAC. Its incidence is rare and very few cases have been reported in the literature. Its association with exuberant granulation tissue in the mastoid air cell system without extension of Cholesteatoma into middle ear cleft is even rare. This association has been reported for the first time as evident from review of literature.

External auditory canal osteoma resulting in cholesteatoma which is complicated with menengitis

Osteoma of external auditory canal is a unilateral benign tumor which usually presents with no symptoms. They only cause symptoms when cerumen collection or conduction type hearing loss occurs. They are the most common osseous lesions of the temporal bone. It very rarely presents with cholesteatoma. So far, no osteoma case concomitant with, cholesteatoma and meningitis has not been reported. In this article, we report an interesting case presenting with external auditory canal osteoma, cholestatoma and meningitis concomitantly who was treated successfully using the canal Wall-down mastoidectomy technique.

Osteoma of the External Auditory Canal Masquerading as an Aural Polyp: Case Report and Review of Literature

Osteoma of external auditory canal is a rare benign tumour. Usually slow growing, found incidentally and often symptomless. Rarely an osteoma may present as a simple aural polyp and may be mistaken as polyps arising secondary to tuberculous,chronic otitis media or carcinoma. The presentation of an osteoma as an aural polyp is extremely rare, and there have been very few reports published Here we have a case of osteoma in an eighteen years old male arising from the postero-superior wall of the external auditory canal masquerading as an aural polyp, causing decreased hearing and aural fullness which was relieved by removal of the tumour.

Multifocal osteoma of external auditory canal in a child. A case report

Abstract Osteomas of external auditory canal are most often unilateral, solitary, pedunculated hard tumors located on the anterior and superior wall of the structure in its distal part. They have to be distinguished from exostoses of external auditory meatus. Osteomas of external auditory canal are very rare and apart from isolated cases are not described in children population. The case presented in the paper shows the possibility of a presence of unilateral multifocal osteoma of an external auditory canal in a child, which is not described in the literature concerning the topic.
