Osteomas of the middle ear are rare benign neoplasms. Most of the cases caused conductive hearing loss and others were asymptomatic and diagnosed incidentally. We report a case of a huge middle ear osteoma along with compatible radiological findings filling the whole tympanum and the Eustachian tube, which caused intermittent otorrhea and conductive hearing loss.
"The most common symptom of osteomas in the middle ear is a progressive conductive hearing loss, occasionally accompanying otorrhea, and/or tinnitus. The mechanism responsible for this hearing loss involves ossicular chain fixation , dislocation , round window obliteration by the osteoma , or impingement on the tympanic membrane . The obstruction of eustachian tube by osteomas may cause chronic otitis media or otorrhea, and recurrent "
[Show abstract][Hide abstract] ABSTRACT: Since the first description of middle ear osteomas by Thomas in 1964, only few reports were published within the English literatures (Greinwalid et al., 1998; Shimizu et al., 2003; Cho et al., 2005; and Jang et al., 2009), and only one case of the multiple osteomas in middle ear was described by Kim et al., 2006, which arose from the promontory, lateral semicircular canal, and epitympanum. Here we describe a patient with multiple middle ear osteomas arising from the promontory, incus, Eustachian tube, and bony semicanal of tensor tympani muscle. This patient also contracted the chronic otitis media in the ipsilateral ear. The osteomas were successfully removed by performing type III tympanoplasty in one stage.
[Show abstract][Hide abstract] ABSTRACT: Osteomas in the middle ear are extremely rare and are generally solitary and small. We present a case of a 28-year-old female patient with multiple middle ear osteomas which arose from the promontory, epitympanum, and lateral semicircular canal. The osteomas were successfully removed by tympanomastoidectomy. This is the first reported case of a patient with middle ear osteomas arising from multiple sites.

[Show abstract][Hide abstract] ABSTRACT: Osteomas of the middle ear are rare benign tumors. They commonly arise from the promontory. To date, a total of three cases of osteomas of the ossicles, inseparable from malleus and incus, have been described in the English literature. Among them, only one case osteoma with congenital cholesteatoma has been reported. Recently a 6-year-old boy with osteoma associated with congenital cholesteatoma presented to our service. The osteoma and congenital cholesteatoma were removed successfully by canal wall up mastoidectomy with staging operation. A rock-hard mass was separated from the footplate. The malleus and short process of incus were intact. Histopathological examination confirmed the presence of the osteoma.
