Multiple Osteomas in Middle Ear

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.

Middle ear osteoma causing Eustachian tube obstruction: A case report and literature review

“…Osteomas of the temporal bone are rare tumors of unknown origin ( Li et al., 2012 ). Thomas has suggested a genetic etiology in two cases occurring in siblings ( Thomas, 1964 ).…”

Treatment approaches to temporal bone osteomas

“…Nadiren kemikçik zinciri etkileyerek iletim tipi işitme kaybına, DKY ve kulak zarına doğru büyüyerek patolojik görünümlere, yuvarlak pencereye ulaşarak vestibüler semptomlara, fasiyal paraliziye, otore ve tinnitus gibi durumlara neden olabilir. [19] Tomografi görüntüleri, osteomun orijini ve ilişkili olduğu yapıları belirlemede oldukça faydalıdır. [20] Tedavide, olası komplikasyonları göz önüne alındığında asemptomatik hastalarda cerrahi tedaviden kaçınılması, rutin fizik muayene ve görüntüleme ile takibi önerilir.…”

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

“…In most cases, the confirmation of a diagnosis requires CT imaging, along with visual inspection during surgical exploration with histopathological analysis of the biopsied or excised specimen [6]. …”

“…Only one other case of middle ear osteoma presenting with facial nerve weakness is found in the literature [ 5 ]. In most cases, the confirmation of a diagnosis requires CT imaging, along with visual inspection during surgical exploration with histopathological analysis of the biopsied or excised specimen [ 6 ].…”
