Pearls and Nuances in Vagal Nerve Stimulator Implantation Surgery

Abstract

Vagal nerve stimulation (VNS) is a proven effective modality of treatment for drug refractory epilepsy and major depression. Recently, the indications have been expanded to various other non-neural indications. The key to a successful surgery includes identification of the vagus nerve and proper application of the device. Meticulous dissection and proper handling of the nerve leads to maximizing therapeutic effect and minimizing complications. In the current article, we describe the technical aspects of performing VNS, focusing on the anatomical variants and intraoperative adjuncts to identify the vagus nerve accurately.
