“…169 Although previous invasive procedures include destructive lesions such as trigeminal nerve sectioning, 170 these have largely been replaced by implantable neuromodulation devices. Occipital nerve stimulation was found to be effective in several open label studies of 44-105 patients, [171][172][173][174] and more recently in a randomized dose controlled trial of 131 participants with medically refractory chronic cluster headache (defined as non-response to, intolerance of, or a contraindication to verapamil, lithium, and one other preventive drug). 174 Greater occipital nerve blocks were not predictive of response to occipital nerve stimulation, 175 but occipital nerve stimulation likely has a similar mechanism of action via modulation of the trigeminocervical complex.…”

Complications of occipital nerve stimulation included infection, stimulator lead problems such as migration and fracture, and pain at the lead or generator sites.…”

“…In a unique international, multicentre, randomised, double-blind, phase 3, electrical dose-controlled clinical trial, 131 patients with drug-resistant CCH underwent 24 weeks of ONS at either 100% ( N = 65, verum) or 30% ( N = 66, sham) of the individually determined range between paraesthesia threshold and near discomfort [ 122 ••]. At the end of the randomisation phase, both groups achieved a 50% response rate in 44.6% of the cases.…”

“…Serious adverse events, such as pain, were reported in 26% of the high-stimulation and 12% of the lowstimulation groups. 33 Non-invasive stimulation of the vagus nerve has been studied for acute treatment of cluster headache in two randomised, sham-controlled trials. There was a significant response in episodic cluster headache, but not chronic cluster headache.…”
