The Incidence of Acoustic Neuromas
Archives of Otolaryngology - Head and Neck Surgery, 1988To the Editor .—Medical literature describes the acoustic neuroma as the most common tumor of the posterior fossa, but its actual incidence or prevalence in the general population is not known. Autopsy studies have found vestibular nerve sheath tumors in 1%, or fewer, of cases.

Management of Acoustic Neuromas
Acta Oto-Laryngologica, 1991A 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 ...

Diagnosis of Acoustic Neuromas
Archives of Otolaryngology - Head and Neck Surgery, 1969THE 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.

Hypervascular acoustic neuroma
Neurological Research, 1998The 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.

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.

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.

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, 1987Small 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.

To define the clinical characteristics of cystic acoustic neuroma, we retrospectively analyzed 22 patients with cystic acoustic neuroma and reviewed the literature with regard to clinical manifestation, imaging features, diagnosis, surgical procedures and prognosis.

The Acoustic Neuroma Association
Otolaryngologic Clinics of North America, 1997The Acoustic Neuroma Association (ANA) was established in 1981 in an effort to improve patients' treatment experiences and subsequent recovery by providing realistic and accurate patient information and by offering opportunities for positive interaction with other acoustic tumor patients.
