AI Article Synopsis
- Peripheral nerve blocks for headache relief, like those targeting the supraorbital nerve, often provide only temporary relief, prompting the study of supraorbital nerve stimulation.
- In a case series involving patients with persistent frontal headaches who responded positively to initial nerve blocks, 16 patients underwent a trial of nerve stimulation.
- Results showed significant decreases in headache scores and a 50% reduction in opioid consumption over 30 weeks post-implantation, indicating that this method may be effective for chronic frontal headaches in selected patients.
Article Abstract
Peripheral nerve blocks of the supraorbital, supratrochlear or occipital nerve have been utilized for the relief of headaches, although relief may be short-lasting. The purpose of this study was to evaluate the efficacy of supraorbital nerve stimulation for treatment of intractable supraorbital neuralgia. Patients presenting to the pain clinic with refractory frontal headaches who responded to a diagnostic supraorbital nerve block were selected for this case series. Patients underwent a trial of supraorbital nerve stimulation, and efficacy was assessed after 5-7 days (n = 16). From the trial, 10 patients consented to undergo permanent implantation of the stimulator. Opioid consumption and headache scores were monitored preoperatively and at timed intervals for 30 weeks. Headache scores decreased, and opioid consumption was reduced in half, and these beneficial accomplishments were maintained up to 30 weeks after implantation. In selected patients, supraorbital nerve stimulation for the treatment of chronic frontal headaches appears to be efficacious.
