A series of 309 awake surgeries with transcortical approach for IDH-mutant low-grade glioma involving the insula: long-term onco-functional outcomes in 253 consecutive patients

This is the largest homogeneous surgical experience of LGGs involving the insula that were resected through the opercula based on awake mapping. The results show a high percentage of functional preservation and return to work, with a high overall survival rate.
