4. Age range: 18-70 years
5. Difficult-to-treat CCH with documented previous complete failure, insufficient efficacy, intolerance, or contra-indications to most preventive CH treatments among which are oral steroids or suboccipital infiltrations, verapamil, lithium carbonate and topiramate.
6. No preventive CH treatment or stable preventive CH medication for ≥ 2 weeks before enrolment. Subject agrees not to change existing treatment during the whole duration of the trial.
7. Subject written informed consent provided before enrolment
8. Subject willing and capable of subjective evaluation and to fill in an electronic CH diary, to understand questionnaires, and to read, understand and sign the written informed consent form.

5. Subjects at high risk of suicide/suicidal ideation in the past one year assessed with the C-SSRS
6. Having another active implanted device such as a cardiac pacemaker, a spinal cord, peripheral nerve, sphenopalatine ganglion, or deep brain hypothalamic stimulator, and/or a drug delivery pump, etc.
7. Cranial botulinum toxin injections in the past 3 months before enrolment. Administration of the following treatments in the last month before enrolment: monoclonal antibodies blocking calcitonin gene-related peptide transmission, suboccipital infiltrations with steroids and/or local anaesthetics, oral steroids, radiofrequency procedure or infiltrations of the sphenopalatine ganglion, opioids WHO 3.
8. Medication overuse headache (ICHD 3 8.2)
9. Inability to fill out an electronic diary.
10. Previous surgery or trauma involving the cervical spine or the occipital bone
11. Coagulopathy or required anticoagulant medications that cannot be safely discontinued in the perioperative period.
12. Concurrent participation in another clinical study
13. Planned pregnancy, pregnancy, or breastfeeding.
