The importance of the auditory evoked potential in acoustic neuromas.
Hearing loss, frequently with tinnitus, is the main symptom of acoustic neuromas (ANs), which compress the cochlear nerve and affect the cochlear blood supply. This vascular mechanism explains why atypical, fluctuating deafness, with audiometric features of retrocochlear involvement, may occur in this condition. An early diagnosis of ANs is essential for a good prognosis. Physicians should reco...
متن کاملInternal auditory canal involvement of acoustic neuromas: surgical correlates to magnetic resonance imaging findings.
OBJECTIVE Factors that play a role in the selection of surgical approach for acoustic neuromas include patient health and age, size of tumor, hearing status, and location of tumor in the internal auditory canal (IAC) and the cerebellopontine angle. Deep extension into the IAC makes hearing preservation extremely difficult when a retrosigmoid craniotomy is used, and the best approach is a middle...
متن کاملAcoustic Neuromas.
Patients with acoustic neuromas have several treatment options that include observation, surgical resection, stereotactic radiosurgery, and fractionated radiotherapy. Resection is indicated for patients with larger tumors that have caused major neurologic deficits from brain compression. Surgeons perform stereotactic radiosurgery as the main alternative to acoustic tumor resection with the goal...
متن کاملFour cases of acoustic neuromas with normal hearing.
In 95 percent of the cases, patients with acoustic neuromas will have some magnitude of hearing loss in the affected ear. This paper reports on four patients who had acoustic neuromas and normal hearing. Results from the case history, audiometric evaluation, auditory brainstem response (ABR), electroneurography (ENOG), and vestibular evaluation are reported for each patient. For all patients, t...
متن کاملAcoustic neuromas in children.
Although unilateral acoustic neuromas in children are rare, they do occur. There is no gender predilection and the clinical symptoms and signs are similar to those seen in adults. They tend to occur in the absence of neurofibromatosis and are usually benign. Our patient is the youngest yet reported with documented unilateral acoustic neuroma; moreover; she is the first child in whom this tumor ...
