OBJECT: The standard treatment for @entity1653 is complete resection, but the proximity of skull base @entity1653 to @entity531 makes complete excision of the lesion difficult or impossible. The authors analyzed the mid- and long-term results obtained in @entity1 treated with postresection Gamma Knife surgery (GKS) for residual or recurrent @entity1653 of the cranial base. METHODS: Thirty-six @entity1 with residual or recurrent @entity1653 of the skull base following one or more surgical procedures underwent GKS. There were 31 @entity1 and five @entity1 , ranging in age from 22 to 73 years. The median @entity5 volume was 4.1 ml (range 0.8-20 ml) and the median radiation dose to the @entity5 margin was 16 Gy (range 15-16 Gy). RESULTS: @entity1 were followed for a median of 81 months (range 30-141 months) after GKS. At the end of the follow-up period, overall neurological improvement was observed in 16 @entity1 (44.4%), whereas the condition in 20 @entity1 (55.6%) was unchanged. One @entity1 suffered transient @entity2657 6 months after GKS. Based on imaging documentation, a partial response was seen in five @entity1 (13.9%), the disease remained stable in 30 @entity1 (83.3%), and in one @entity1 (2.8%) there was an increase in @entity5 size. The actuarial progression-free survival rate was 100% at 5 years and 94.7% at 10 years. CONCLUSIONS: Gamma Knife surgery was shown to be an excellent adjunct to resection because of its durable rate of @entity5 control and low @entity137 . It should be initially considered along with surgery for the treatment of complex skull base @entity1653 .

Postoperative Gamma Knife surgery for XXXX of the cranial base.
