A comparative study of microsurgery and gamma knife radiosurgery in vestibular schwannoma evaluating tumor control and functional outcome

Abstract

<i>SRS</i> can achieve similar tumor control compared to <i>SURGERY</i> in smaller VS (Koos I and II)-with similar postinterventional morbidities. In large VS (Koos III and IV), long-term tumor control of <i>SRS</i> is inferior to <i>SURGERY</i>. Based on these results, we suggest that if combination therapy is chosen, the residual tumor should not exceed the size of Koos II.
