Predictors of trigeminal neuropathy in patients receiving Gamma Knife stereotactic radiosurgery for vestibular schwannoma
The only significant factor in the risk of development of Tn after SRS for VS was the volume of CN V that received ≥ 11 Gy. This should be routinely incorporated into dosimetric planning constraints and patients should be counseled about the risk of adverse effects if it cannot be met. For those with growing VS and a gap to the trigeminal nerve, it may be prudent to provide earlier treatment with SRS to enable application of this dosimetric constraint and reduced risk of Tn.
