Neuronavigated fiber dissection with pial preservation: a laboratory model to simulate opercular approaches to insular tumors

Background Advances in the oncological and functional results of insular surgery have been reported recently. Such successes have been made possible by the advent of the transopercular approach under awake monitoring and by the improved anatomical and functional knowledge of the white matter pathway...
