Abstract
Stereotactic cerebral irradiation is a radiotherapeutic technique for precise delivery of ionizing irradiation to an intracranial target with simultaneous sparing of adjacent parenchyma. Treatment can be administered by a multi-source cobalt-60 device (gamma knife) or a dedicated linear accelerator.The target dose can be delivered in a large, single fraction (stereotactic radiosurgery SRS) or in multiple, daily increments (stereotactic radiotherapy SRT). The latter approach combines the physical dose localization advantages of SRS with the radiobiologic benefits of dose fractionation. This literature review will present the rationale and clinical results of SRS and SRT for the treatment of acoustic neuromas. Emphasis will be placed on tumor control, imaging outcome and cranial nerve preservation. The findings demonstrate that SRS and SRT represent reasonable therapeutic options for patients with acoustic neuromas.
