Abstract
Objective: Occipital Nerve Stimulation (ONS) is increasingly used to treat a range of chronic, refractory headache conditions, most notably chronic cluster headache (CCH). Despite this, there is still no consensus on the optimal implantation technique. Clinical reports and reviews in the field have reported remarkably high complication rates of which several can be directly related to the surgical approach. We here describe a comprehensive and detailed surgical approach used at Aarhus University Hospital, Denmark, aiming to improve paresthesia coverage and minimize complications.
Methods: The implantation procedure described here is performed with a sleep-awake anesthetic regimen in a lateral position using anatomical landmarks and perioperative testing based on patient feedback. A single lead is subcutaneously implanted from behind the ear and across the back of the head, and the implantable pulse generator (IPG) is placed below the right clavicle.
Results: From March 2018 to June 2024, 45 CCH patients were implanted using this approach and followed up for a total of 86.3 patient years. A total of 22 adverse events (AEs) occurred in 17 patients, with nine AEs requiring revision surgery. Notably, no instances of lead migration, lead breakage, or muscle/neck stiffness were observed. Temporary occipital dysesthesia was the most frequent non-surgical AE, resolving spontaneously within weeks. The rate of serious adverse events (SAEs) was one per 9.6 patient years. Six patients had the ONS system explanted due to lack of efficacy.
Conclusions: The surgical approach described here in detail offers several advantages, with a favorable complication profile, satisfactory paresthesia coverage, and good perioperative patient comfort. Advances in the surgical technique are vital to both patients and healthcare providers, and we believe this approach is a valuable contribution toward improved patient outcomes and procedural efficiency.
期刊介绍：
Pain Practice, the official journal of the World Institute of Pain, publishes international multidisciplinary articles on pain and analgesia that provide its readership with up-to-date research, evaluation methods, and techniques for pain management. Special sections including the Consultant’s Corner, Images in Pain Practice, Case Studies from Mayo, Tutorials, and the Evidence-Based Medicine combine to give pain researchers, pain clinicians and pain fellows in training a systematic approach to continuing education in pain medicine. Prior to publication, all articles and reviews undergo peer review by at least two experts in the field.
