Unilateral occipital nerve stimulation for bilateral occipital neuralgia: a case report and literature review

Atypical refractory occipital neuralgia treated with a unilateral dual-lead occipital nerve stimulator: a case report

Aim: To describe the successful treatment of atypical occipital neuralgia (ON) using a unilateral dual-lead occipital nerve stimulator. Setting: Outpatient clinic/operating room. Patient: A 53-year-old male with atypical ON. Case description: Patient was previously diagnosed with treatment-refractory left-sided trigeminal neuralgia with atypical occipital distribution. On presentation, his symptoms were consistent with ON with distribution to the left fronto-orbital area. He received a left-sided nerve stimulator implant targeting both the greater and lesser occipital nerves. Results: Patient reported pain relief from a numerical rating scale 10/10 to 3-4/10. Conclusion: ON with referred ipsilateral trigeminal distribution should be considered when patients present with simultaneous facial and occipital pain. Further, a dual-lead unilateral stimulator approach may be a viable treatment.

Neuromodulation in headache and craniofacial neuralgia: guidelines from the Spanish Society of Neurology and the Spanish Society of Neurosurgery

INTRODUCTION

Numerous invasive and non-invasive neuromodulation devices have been developed and applied to patients with headache and neuralgia in recent years. However, no updated review addresses their safety and efficacy, and no healthcare institution has issued specific recommendations on their use for these 2 conditions.

METHODS

Neurologists from the Spanish Society of Neurology's (SEN) Headache Study Group and neurosurgeons specialising in functional neurosurgery, selected by the Spanish Society of Neurosurgery (SENEC), performed a comprehensive review of articles on the MEDLINE database addressing the use of the technique in patients with headache and neuralgia.

RESULTS

We present an updated review and establish the first set of consensus recommendations of the SEN and SENC on the use of neuromodulation to treat headache and neuralgia, analysing the current levels of evidence on its effectiveness for each specific condition.

CONCLUSIONS

Current evidence supports the indication of neuromodulation techniques for patients with refractory headache and neuralgia (especially migraine, cluster headache, and trigeminal neuralgia) selected by neurologists and headache specialists, after pharmacological treatment options are exhausted. Furthermore, we recommend that invasive neuromodulation be debated by multidisciplinary committees, and that the procedure be performed by teams of neurosurgeons specialising in functional neurosurgery, with acceptable rates of morbidity and mortality.
