“…Some authors have indicated that clini-caIly osteomata (sensu Sheehy, 1958) are very rare; one survey of the literature noted only five cases in 15 years of combined medical practice (Kline and Pearce, 1954). Obviously with such a small clinical sample the etiology of this type of lesion has not been clearly established nor has it been established that the two forms differ in etiology.…”

The frequency of auditory exostoses was examined by latitude. It was found that discrete bony lesions of the external auditory canal were, with very few exceptions, either absent or in very low frequency (less than 3.0%) in 0-30 degrees N and S latitudes and above 45 degrees N. The highest frequencies of auditory exostoses were found in the middle latitudes (30-45 degrees N and S) among populations who exploit either marine or fresh water resources. Clinical and experimental data are discussed, and these data are found to support strongly the hypothesis that there is a causative relationship between the formation of auditory exostoses and exploitation of resources in cold water, particularly through diving. It is therefore suggested that since auditory exostoses are behavioral rather than genetic in etiology, they should not be included in estimates of population distance based on nonmetric variables.

“…Typically, these tumors appear as solitary, unilateral, and pedunculated lesions located in the lateral bony ear canal [3]. Osteomas can be differentiated from exostoses, since the latter usually presents as multiple, bilateral, and broad-based elevations of the medial bony external auditory canal [4].…”

“…Lesions arising from the temporal bone itself are rare [ 1 , 2 ]. Osteomas are the most widespread neoplasms of the temporal bone [ 3 ]. They tend to occur in the external auditory canal but can also occur in other parts of the temporal bone, such as the middle ear space [ 3 , 4 ], where the facial nerve is situated.…”

Middle ear osteoma causing progressive facial nerve weakness: a case report

et al. 2014

IntroductionFacial nerve weakness is most commonly due to Bell’s palsy or cerebrovascular accidents. Rarely, middle ear tumor presents with facial nerve dysfunction.Case presentationWe report a very unusual case of middle ear osteoma in a 49-year-old Caucasian woman causing progressive facial nerve deficit. A subtle middle ear lesion was observed on otoscopy and computed tomographic images demonstrated an osseous middle ear tumor. Complete surgical excision resulted in the partial recovery of facial nerve function.ConclusionsFacial nerve dysfunction is rarely caused by middle ear tumors. The weakness is typically due to a compressive effect on the middle ear portion of the facial nerve. Early recognition is crucial since removal of these lesions may lead to the recuperation of facial nerve function.

“…An erosive benign fibro-osseous lesion of the external auditory canal (EAC) is rarely seen. We found only four cases during our review of literature spanning the last 15 years [ 1 ]. The term fibro-osseous lesion is a generic term encompassing a wide range of disorders ranging from inflammatory to neoplastic that microscopically exhibit a connective tissue matrix, which contains a variable amount of mineralized substance that may be osteoid or cementum-like.…”

The term fibro-osseous lesion encompasses a spectrum of disorders ranging from inflammatory to neoplastic that microscopically exhibit a connective tissue matrix containing formless trabeculae of compact bone. Characteristically, they are located over healthy bone, from which they are abruptly differentiated. The majority of the lesions arise from the maxillofacial region; the occurrence of a lesion in the external auditory canal (EAC) being extremely rare as is in our case. The lesions present with a range of symptoms ranging from conductive hearing loss, Eustachian tube obstruction to bone erosion that develop due to the mass effect. We report a case of a 35-year-old male patient who presented with insidious onset left aural fullness, decreased hearing followed by intermittent mucopurulent discharge from the ear, who was eventually diagnosed with a benign fibro-osseous lesion of the external auditory canal.
