Familial Osteoma of the Middle Ear

Abstract

described with the help of photographs two cases of osteoma of the middle ear occurring in a brother (age 10), both ears, and sister (age 6) left ear. The two older children in this family do not appear to have this condition and there is no family history of deafness. X-rays of the boy's mastoids do not^demonstrate these small tumours and both are reasonably well pneumatized. Each child had previously undergone tonsillectomy and adenoidectomy for indications which included exudative otitis media. This had recurred later and was not relieved permanently by suction myringotomy.In the boys case exploration by the Rosen approach revealed on each side a smooth broad-based osteoma arising in the region of the pyramid. The tumour had extended forward to become adherent to the incudostapedial joint which it had immobilized. As much as possible of the tumour was drilled away and the ossicular chain mobilized. The drums now appear normal and the hearing is audiometrically normal.In the girl's case an excess of clear mucus was the only abnormality visible in the right ear. In the left ear a tumour similar to the brother's but slightly smaller was found and drilled away. The drum and hearing are now normal.The aetiology of this condition is obscure. Exostoses outside the drum have been attributed to swimming; but the children although they visited * A paper read at a

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

“…The first report cases involved a pair of siblings and thus a genetic etiology was suggested [7]. However other possible causes, such as chronic inflammation due to exudative otitis, have also been proposed and the precise etiology of middle ear osteoma has yet to be clarified.…”

Since osteomas of the middle ear were first described by Thomas in 1964 which occurred in a brother and sister [9], only a few cases have been reported in the English literature.
