Epidemiology of acoustic neuromas

The Journal of Laryngology & Otology, 1984
In Denmark one surgical team, during the last 7 years, has performed about 80 per cent of all acoustic neuroma surgery. Because of this centralization, in such a limited population as that of Denmark, we have attempted to make a epidemiological survey of all diagnosed tumours in the period from 1976 to 1983. Systematic and prospective records were made

Management of Acoustic Neuromas

Acta Oto-Laryngologica, 1991
A survey of the management of acoustic neuromas in the broadest sense is given. The epidemiology and pathogenesis is described. The clinical development may take any imaginable course, and even though a slowly progressing unilateral hearing impairment, of the sensorineural type, is the main pattern of presentation, it is stressed that any type of ...

Hypervascular acoustic neuroma

Neurological Research, 1998
The authors present a patient with a large acoustic neuroma that exhibited an unusual vascular architecture. Magnetic resonance imaging demonstrated multiple flow voids in and around the mass. At surgery, intra- and extratumoral vascularity was arterialized due to luxurious shunting.

Calcified Acoustic Neuroma

Southern Medical Journal, 1989
As our case indicates, it should be kept in mind that calcification, though unusual, does occur in acoustic neuromas. The statistical tendency of acoustic neuroma and meningioma to have different signal characteristics on magnetic resonance imaging may make MRI useful in increasing specificity in preoperative diagnosis.

Diagnosis of Acoustic Neuromas

Archives of Otolaryngology - Head and Neck Surgery, 1969
THE EXPERIENCE of the last few years has proven that the number of acoustic tumors found is in direct relationship to the index of suspicion for such a lesion by the otologist. The possibility of an acoustic tumor should be entertained in all cases of unilateral cochlear or vestibular loss of unknown origin.

Acoustic Neuroma Update

Otolaryngologic Clinics of North America, 1996
We have described refinements and alternative techniques in the management of acoustic neuromas. The outcome for patients with both unilateral and bilateral tumors continues to improve.

Acoustic Neuromas in the Elderly

Otology & Neurotology, 2001
To determine if an "observation" protocol with serial scanning is a safe and effective management paradigm for acoustic neuromas in the elderly.A retrospective case review was performed.This study was performed in an academic, tertiary care center.Forty-one patients over the age of 65 years were identified with the primary diagnosis of unilateral ...

Bilateral acoustic neuromas

Clinical Otolaryngology, 1993
This article reviews 12 patients with bilateral acoustic neuromas. The sex incidence was equal and the mean age at diagnosis was 26.2 years. The family history was positive in nine of the patients. Five patients have had incomplete surgical removal of acoustic neuromas on both sides.

Bilateral Acoustic Neuromas

Journal of Speech and Hearing Disorders, 1972
A case is presented of a 17-year-old female with bilateral acoustic neuromas not associated with multiple neurofibromatosis. The progressive nature of the hearing loss, retrocochlear audiometric test results as well as physical symptoms suggested bilateral acoustic neuromas. Both neuromas were removed with resulting total hearing loss.

The Origin of Acoustic Neuromas

Acta Oto-Laryngologica, 1987
Small acoustic neuromas, operated on through transpetrosal approaches were studied by light and transmission electron microscopy. All schwannomas were found to interpenetrate the vestibular ganglion without a space or a capsule. In the abnormal ganglion areas, free tumour Schwann cells were observed.
