This article summarizes tumor control and functional outcomes of stereotactic radiosurgery (SRS) for patients with nonvestibular schwannomas, in comparison with those treated with microsurgical resection. To date, surgical resection has been a common treatment for nonvestibular schwannomas. Because these tumors are generally benign, complete tumor resection is a desirable curative treatment. However, it is almost infeasible to completely remove these tumors without any complications, even for experienced neurosurgeons, because of adherence to surrounding critical structures such as cranial nerves, brainstem, or vessels. SRS provides a good tumor control rate with much less morbidity than microsurgical resection.
