[Radiation Therapy for Cerebellopontine Angle Tumors:In the Standpoint of Gamma Knife Radiosurgery].

Stereotactic radiation therapy, including stereotactic radiosurgery, is a well-established and effective treatment for cerebellopontine angle tumors such as meningiomas, vestibular schwannomas, trigeminal and jugular foramen schwannomas, and glomus tumors. It offers high rates of tumor control while preserving neurological function, particularly in tumors smaller than 3 cm, which are ideal candidates for stereotactic radiosurgery. Large tumors or those extending beyond the skull base can also be managed effectively using fractionated stereotactic radiation therapy. As such, a multidisciplinary approach that combines surgical resection with stereotactic radiation therapy is a valuable strategy, especially when functional preservation is a key therapeutic goal.
