Occipital nerve stimulation (ONS) is shown to be effective in treating various forms of headache. Most studies describe the treatment of occipital neuralgia (ON), but in many patients, the clinical description could also correspond to cervicogenic headache (CGH) or occipital migraine (OM). These different entities (ON, CGH, and OM) may be grouped together under the term occipital headaches. ⋯ The results of this large series confirm that ONS is an effective treatment option for patients with intractable occipital headaches, but the frequency of complications remains quite high and must be taken into account in the surgical decision.

Objective real-world experience with peripheral nerve stimulation (PNS) is limited. Furthermore, the lack of robust outcome metrics, long-term follow-up and data comparing responders and nonresponders limit the refinement of selection criteria to better identify patients likely to benefit from PNS. ⋯ The present study adds to the PNS literature by providing long-term data and multiple outcome metrics in a subset of patients. We suggest that BDI, PCS, and MPQ may provide more insight into meaningful response over time. Evaluating functional and quality of life outcomes in patients with craniofacial pain may be more informative than assessing benefit solely based on pain intensity and responder rates.

In vagal nerve stimulation (VNS) therapy, the release of VNS model 106 (AspireSR) allowed for responsive VNS (rVNS). rVNS utilizes a cardiac-based seizure detection algorithm to detect seizure-induced tachycardia to trigger additional stimulation. There are some studies suggesting clinical benefits of rVNS over traditional VNS, but the performance and significance of autostimulation mode in clinical practice are poorly understood. ⋯ The initiation of autostimulation mode in VNS therapy increased the total number of stimulations. Shortening the OFF-time leads to a decreased number and share of automatic activations. Epilepsy type may affect autostimulation activity.
