Quality and rate of preserved hearing are crucial to make hearing preservation surgery a viable treatment. A long-term experience with hearing preservation surgery, with tumour size and hearing as admission criteria, was evaluated to assess which size and hearing allowed a high rate of success. The hearing outcome in relation to size of tumour and pre-operative hearing was retrospectively revie...

Despite the potential importance of the cell cycle and apoptosis pathways in brain tumor etiology, little has been published regarding brain tumor risk associated with common gene variants in these pathways. Using data from a hospital-based case-control study conducted by the National Cancer Institute between 1994 and 1998, we evaluated risk of glioma (n = 388), meningioma (n = 162), and acoust...

BARROW QUARTERLY • Vol. 20, No. 4 • 2004 Acoustic Neuromas: Symptoms and Diagnosis A understanding of the clinical manifestations of acoustic neuromas is essential for diagnosis. Once this lesion is suspected, the appropriate diagnostic tests are vital for treatment planning and pretreatment discussions with the patient. This article reviews the clinical presentation and diagnostic evaluation o...

The response of patients with tinnitus to the suppressive effects of IV furosemide is about 50%. Since furosemide is a drug without known effects on the central nervous system but with well documented effects in the auditory periphery, we hypothesized that it suppressed tinnitus of peripheral origin and that the response rate was due to that selectivity. To test this hypothesis we recruited 14 ...

Although the diagnostic reliability of auditory brainstem responses (ABR) in acoustic neuromas has been revised due to its poor sensitivity (demonstrated above all in smaller tumours), and its limited specificity, this method is still used as the initial otoneurological approach. To contribute to the clinical use of this method, in particular with the aim of reducing the number of false positiv...

OBJECTIVE To evaluate the complications and sequelae of acoustic neuroma surgery, according to tumour size. PATIENTS AND METHOD A retrospective analysis of 120 patients who underwent microsurgical resection of vestibular schwannomas between November 1994 and September 2006 was undertaken. Tumour size, extent of removal, preservation of facial and cochlear nerves, complications, and sequelae w...

  Background and Objective: Approximately 45% of benign peripheral nerve sheath tumors (PNST) occur in head and neck regions. Malignant peripheral nerve sheath tumors (MPNST) are less common and only 8-15% of these tumors occur in head and neck region. In this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family h...
