Peripheral Nerve Stimulation for Facial Pain Using Conventional Devices: Technique and Complication Avoidance.

Abstract

The introduction of peripheral neuromodulation to treat headache and facial pain two decades ago opened up the field to non-neurosurgical practitioners, given the relatively low risk and technical ease of the procedure. These procedures, primarily occipital nerve stimulation (ONS) and trigeminal branch stimulation such as supra- and infraorbital nerve stimulation, are now established to be effective in a number of facial pain and headache syndromes, despite their lack of approval by regulatory agencies such as the US Food and Drug Administration (FDA). For that reason and others, dedicated hardware for these procedures has not yet been developed, thus relying on hardware designed for placement in the epidural space for spinal cord stimulation (SCS). This has led to a series of technical issues and device-related complications not traditionally seen with SCS. I will review the surgical technique of ONS and peripheral nerve stimulation of the head and face utilizing this equipment, and discuss methods learned by experienced practitioners over the years to minimize device-related complications.
