“…The origin of the osteoma in our patient, as well as that reported by Yamasoba et al [3] and the second patient of Silver et al [2], may have been an inflammatory reaction of the periosteum [4], However, another case described in the literature [5] presented no history of otitis media. The fact that familial cases have been reported [6] and the increased frequency of onset in those regions that, not being covered by mucosa, are not susceptible to infections (temporal squama, the internal auditory canal, the pe trous apex and the styloid process), but are susceptible to injury, seems to indicate that there must be more than one cause for the development of osteomas.…”

Osteomas of the middle ear are rare lesions. We report the case of a 20-year-old male with osteoma originating from the promontory coincident with tympanic membrane perforation. Histopathological diagnosis was performed by means of a superficial curettage during surgery, to avoid a cochlear fenestration. Postoperative closure of the air-bone gap after myringoplasty confirmed the presumed asymptomatic nature of these lesions.

<p>Osteoma is a benign slow growing bone tumour with predominance in long bones, and is rare in the skull. They are a rare occurrence in the mastoid temporal bone, being usually asymptomatic and treated mainly for cosmetic reasons. We report a case of a young female who presented with a history of swelling in the left post aural region since 10 years. Swelling was gradually increasing in size and was painless. Patient underwent excision of the tumour without any significant complication. As per our knowledge this appears to be the largest tumour reported in literature. The clinical presentation and radiological features of osteoma are characteristic but differential diagnosis should include eosinophilic granuloma, giant cell tumour, monostotic fibrous dysplasia, solitary variant of multiple osteoma, and osteoblastic metastasis. Osteomas present on the mastoid or squamous portion of the temporal bone need to be dealt for cosmetic purposes or if they are causing symptoms, while surgery should include careful removal of periosteal cover and safe margin of the mastoid cortex around it. </p>

Friedberg travmayı izleyen periostitin predispozan faktör olduğunu öne sürmüştür 2 . Birçok yazar osteomların preosseoz konnektif dokudan kaynaklandığını düşünmüş-lerdir karakteristik olmakla birlikte, ayırıcı tanıda eozinofilik granülom, dev hücreli tümör, monostotik fibröz displazi ve osteoblastik metastazlar dikkate alınmalıdır 7 .…”
