The treatment of giant acoustic neuromas
It is widely accepted that giant acoustic tumors (4 cm or more in diameter) require surgical treatment. However, this is a demanding technical procedure, with possible postoperative neurological dysfunction and complications. Giant tumors are frequent in specialized centers, representing about 15% of the total number of acoustic neuromas. The size of the tumor is an important factor concerning ...
متن کاملHearing preservation in acoustic neuroma resection: Analysis of petrous bone measurement and intraoperative application
BACKGROUND There is an increased risk for labyrinthine injury for the resection of acoustic neuromas (AN) on the suboccipital, retrosigmoid approach. Prognostic factors should be analyzed for the postoperative hearing function. METHODS We examined 51 patients with ANs using preoperative intact hearing function. Audiological data were obtained by pure tone audiogram (PTA) and speech audiogram....
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.
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 کاملOutcome of hearing preservation related to tumor morphologic analysis in acoustic neuromas treated by gamma knife radiosurgery
BACKGROUND Gamma Knife radiosurgery (GKRS) is an important part of the neurosurgical armamentarium in the treatment of acoustic neuromas. However, the treatment outcome related to the morphology of the tumor has not been rigorously studied. In this cohort, we evaluated the morphological features of the tumor in the tumor response and neurological outcomes after GKRS. MATERIAL AND METHODS From...
