Stereotactic Gamma Knife Radiosurgery for Vestibular Schwannomas: Trade-offs between Total Tumor Resection and Postoperative Sequelae

Abstract

Since schwannonmas are abnormal nerve sheath neoplasms that may originate from any cranial, peripheral or autonomic nerves. In this article we object to clear the differences between the traditional operation and Gamma knife radiosurgery where the schwannomas are large enough. We might trade off both complete remove with nerve injury and part resection with nerve reservation. We find that Gamma knife radiosurgery is currently an optimal treatment option for patients with higher residual intracranial tumors. The benefits include nerve function preservation and significantly decreased risk of recurrence. This stereotactic radio surgery works does not remove the tumor completely, rather it distorts the DNA of tumor cell and causes these cell s to lose their ability to re-grow. We surveyed patients with an uneventful postoperative period who were usually given the option to be discharged within a postoperative day after a contrast enhanced computed tomography or magnetic resonance imaging of the vestibular schwannomas. This stud y observed some cases of postoperative sequelae and examines the trade-off between such damage and nerve function preservation on patients by using Gamma knife radiosurgery.
