  "abstract": "Background and Aims Chronic facial pain is often driven by various underlying mechanisms and can severely impact patients‘ quality of life. Peripheral nerve stimulation (PNS) emerges as a promising therapeutic option for managing chronic facial pain, offering potential relief where conventional treatments may fall short.Methods The patient, a 74-year-old male with a history of post-traumatic refractory facial pain, underwent PNS implantation targeting the Sphenopalatine ganglion (SPG) and auriculotemporal nerve (ATN). Patient consent was secured for the procedure and the case report. The patient received two successful diagnostic blocks, followed by a trial stimulation period of one week, in preparation for permanent implantation.Results nt implantation. Results: The patient reported a significant reduction in headache frequency and intensity following the trial period. The VAS score decreased from 9/10 to 3/10. A decision to postpone definitive implantation was made, and at the 3-month follow-up, the patient continued to experience substantial pain relief with a VAS score of 2/10 and a reduction in headache episodes from daily occurrences to bi-weekly. Surveys were done to reassess the condition after two years with persistent results supporting evidence for long-term pain relief.Abstract P046 Figure 1Fluoroscopy, lateral view, stimulator lead parallel to auriculotemporal nerve trajectoryAbstract P046 Figure 2Lateral fluoroscopy, sphenopalatine ganglion introducer placementAbstract P046 Figure 3Lateral fluoroscopy, stimulator leads in sphenopalatine ganglion and auriculotemporal nerveConclusions PNS with combined SPG and ATN stimulation can offer a viable and effective treatment option for patients with chronic facial pain. The substantial decrease in pain intensity and frequency and its persistence for months after trial removal highlight the value of shorter term implants not only in preparation for future longer lasting implants, but also as a possible standalone therapy. Further studies with larger cohorts are warranted to establish long-term efficacy and safety",
