Vestibular schwannoma radiosurgery

Vestibular schwannoma radiosurgery is equally effective for younger and older patients. Complications other than hearing deterioration are uncommon. However, malignant transformation is possible, and long-term post-SRS surveillance MRI is important. These data are useful for decision-making involving young adults with VSs 1).

It is an important management option for patients with small- and medium-sized vestibular schwannomas.

Stereotactic radiotherapy techniques aim to control tumor growth with minimal toxicity. Stereotactic radiosurgery (SRS) using either a cobalt unit or a linear accelerator has given high rates of tumor control and of cranial nerve function preservation with marginal doses range of 12-14 Gy. Fractionated stereotactic radiotherapy (FSRT) is optimal for tumors larger than 3 cm. Doses as low as 50.4 Gy provide excellent control rates and low morbidity. Overall, both SRS and FSRT are equally effective and safe options for neuroma patients who do not need immediate surgical decompression 2).
