Middle Ear Osteoma Causing Mixed Hearing Loss: A Case Report

Middle Ear Osteoma With Assimilation of Ossicles: An Unusual Case of Conductive Hearing Loss

We present a case report of a middle ear osteoma presenting as gradual unilateral conductive hearing loss in a healthy 32-year-old lady. The decision for treatment was influenced by the relatively small burden of the disease, and the size and location of the osteoma, which made the decision for surgical excision prohibitively difficult. Taking patient wishes and circumstances into account, the decision was made for a bone conduction hearing implant in conjunction with close follow-up.

Ossicular osteoma of the malleus—A rare diagnosis of middle ear mass

Osteoma of the middle ear (MEO) is a rarity. Due to the benign nature and slow growth rate, MEO are often occasionally found by chance. Possible unspecific clinical symptoms may be conductive hearing loss, tinnitus, effusion, and a sense of fullness. If the osteoma is small and not visible in the otoscopic inspection, it may be confused with other conductive hearing loss etiologies, such as otosclerosis. Nevertheless, one should be aware of this rare but important differential diagnosis of middle ear lesions. This article presents an MEO case causing conductive hearing loss and outlines the diagnostic approach with computed tomography.

An Unusual Cause of Hearing Loss: Incudal Osteoma

Osteoma is common in the temporal bone but extremely rare in the middle ear cavity and incus. Computed tomography plays an important role in the diagnosis of this slow growing benign osseous mass. The treatment of this lesion, which usually causes conductive type hearing loss, includes follow-up and surgery according to the patient's condition.

Benign bony tumors of the paranasal sinuses, orbit, and skull base

Benign bony tumors of the skull base and paranasal sinuses are uncommon entities, with an overall higher incidence in males. Benign bony tumors may lead to local expansion with resultant mass effect of potentially critical structures. Some benign bony tumors may undergo malignant transformation. This article reviews the presentation and management of benign bone tumors of the skull base and paranasal sinuses with special consideration to involvement of the adjacent orbit, intracranial and critical neurovascular structures. This review covers tumor incidence, location, gross and histologic appearance as well as radiographic findings, treatment, and recurrence rates. Tumors discussed in this article include osteochondromas, osteomas, osteoid osteomas, aneurysmal bone cysts, fibrous dysplasia, giant cell tumors, cemento-ossifying fibroma, ameloblastic fibro-odontoma, ecchordosis physaliphora, chondromyxoid fibroma, primary chronic osteomyelitis, primary chronic osteomyelitis, osteochondromyxoma, and dense bone islands.

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

Middle ear osteoma is an extremely rare benign tumor of the middle ear. Due to its very slow growth rate and benign nature, osteoma of the middle ear can be found incidentally without causing any symptoms. The most common clinical signs are conductive hearing loss, the sense of fullness in the ear, tinnitus, and otorrhea. Small-sized osteomas can be misdiagnosed as otosclerosis without showing any signs other than conductive hearing loss. When the mass becomes very large, and symptoms caused by the tumor increase, treatment also becomes difficult. In this paper, we report a case of middle ear osteoma causing conductive hearing loss and effusion due to the effect of pressure on the middle ear ossicles and the Eustachian tube. We also present a review of the pertinent literature.

An uncommon cause of conductive hearing loss

The current video presents the surgical management of a middle ear osteoma through a retroauricolar endocanalar approach, under local anesthesia. The video contains patient's medical history, pre-operative radiological evaluation, surgical approach to the lesion and clinical follow up.

[Middle ear osteoma: case report and literature review]

The short literary review of frequency of occurrence, complaints, results of diagnostics and surgical treatment of patients about osteomine is presented to a drum cavity in article. Two own cases of clinical inspection and surgical treatment of patients about osteomine of a drum cavity are described.

Promontory osteoma mimicking otosclerosis: case report

OBJECTIVE

This case report presents a middle-ear osteoma mimicking otosclerosis that was located at the promontory. The osteoma was successfully excised using an endoscopic transcanal approach without any complication.

CASE REPORT

A 21-year-old man presented with a 4-year history of progressive conductive hearing loss (47 dB with a 30-dB air-bone gap) with intermittent tinnitus of recent onset in his right ear. Endoscopic transcanal middle-ear exploration showed that an osteoma located on the promontory was restricting the mobility of the stapes by affecting the anterior crus of the stapes. After transcanal resection of the osteoma, pure tone audiometry improved to 23 dB with a 5-dB air-bone gap. Tinnitus resolved spontaneously without any additional treatment.

CONCLUSION

Promontory osteomas, a rare and usually asymptomatic clinical entity, should be taken into consideration in the differential diagnosis in patients with progressive conductive hearing loss and tinnitus with intact stapedial reflexes and normal otoscopic findings.
