This study compares prospectively 101 patients with vestibular schwannoma (VS), which were treated at one institution with either stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (SRT). For the first time, the effects of radiotherapy on the hearing function are characterized in detail. The tumor control rates of both SRS and SRT noted very high (SRS 95,4%, SRT 97%) and both techniques achieved a high-grade conservation of the hearing function. The SRS-technique was able to preserve hearing longer than SRT and the SRS showed a slight advantage concerning the improvement of facial neuropathy, too. On the other hand, nearly twice as much patients deafend under SRS than under SRT. As well, more trigeminal neuropathies could be healed with the SRT-technique. In this study, different volumes of tumor turned the balance for using one or the other method, so it should be considered that a direct comparison is limited.
