Frameless stereotactic dual lead placement through single burr hole: A technical report.

Deep Brain Stimulation (DBS) surgery is a neurosurgical procedure involving the placement of stimulatory leads in subcortical structures. Rarely, DBS requires placement of dual ipsilateral leads. Previously, techniques for placing dual ipsilateral leads through a single burr hole were reported using a traditional stereotactic frame. Here, we demonstrate that dual ipsilateral leads can be safely and effectively placed through a single burr hole using a frameless stereotactic DBS system (NexFrame®) with only simple modifications to existing equipment.
