Facial nerve stimulation in adult cochlear implant recipients with far advanced otosclerosis.

Objectives: The objective of this study was to predict occurrence of facial nerve stimulation (FNS) in cochlear implanted patients for far-advanced otosclerosis (FAO) by correlating preoperative computed tomography (CT)-scan data to FNS and to evaluate FNS impact on hearing outcomes.

Methods: Retrospective analysis on 91 ears (76 patients) implanted for FAO. Electrodes were straight (50%) or perimodiolar (50%).

Internal auditory canal osteoma: Case report and review of the literature.

We report a case of internal auditory canal osteoma and discuss this entity's etiology, natural history, and treatment options. The internal auditory canal osteoma is a rare entity with only a few reports published in the medical literature. Its diagnosis is based on two complementary imaging modalities: thin-slice computed tomography and magnetic resonance imaging.

Temporal bone central giant-cell granuloma presenting as a serous otitis media.

Central giant cell granuloma is a benign intraosseous lesion that most commonly occurs in the facial bones. Its location in the temporal bone is extremely rare and only 20 cases have been reported in the literature. We report a case of an adult female patient presenting with a right serous otitis media and mastoiditis associated with a mixed hearing loss during 6 months.

Diagnosis and management of intracochlear schwannomas.

Objective: To describe and analyze a series of intracochlear schwannomas.

Methods: From 1987 to 2005, 19 patients with schwannomas involving the cochlea were included in this series. Clinical, audiovestibular, and imaging data concerning initial and follow-up visits were collected.

Atypical haemangioma of the internal auditory meatus: a case report.

Haemangiomas involving the internal auditory meatus (IAM) are rare and can mimic other frequent lesions of the IAM such as schwannomas by their clinical and imaging aspects. The case of a patient with an atypical IAM haemangioma fluctuating in size is reported to highlight this diagnostic possibility. A 36-year-old female presented with a sudden and recurrent left sensorineural hearing loss (SNHL).

Langerhans' cell histiocytosis of the labyrinth in adults.

Objective: To describe and analyze three unusual cases of Langerhans' cell histiocytosis of the temporal bone in adults.

Study Design: Retrospective case review.

Setting: A tertiary referral center.

Auditory brainstem implant in bilateral and completely ossified cochleae.

Objective: To report and evaluate the results of auditory brainstem implantation in a case of postmeningitis hearing loss with totally ossified cochleae on both sides.

Study Design: Case report.

Setting: Tertiary referral center.

Management of cholesterol granulomas of the petrous apex based on clinical and radiologic evaluation.

Objective: The purpose of this study was to analyze the imaging characteristics of 12 cholesterol granulomas as a function of their clinical symptoms. The results of the different surgical approaches and the management of these lesions are discussed.

Study Design: Retrospective case review.
