ABSTRACT Persistent occipital neuralgia can produce severe headaches that may not be controllable by conservative or surgical approaches. We describe a case series of 6 patients who had chronic headaches over an average of 4.9 yr who underwent occipital nerve electrical stimulation lead implantation using a modified midline approach. The patients had received conservative and surgical therapies in the past including oral antidepressants, membrane stabilizers, opioids, occipital nerve blocks, and radiofrequency ablations. Significant decreases in pain visual analog scale (VAS) scores and drastic improvement in functional capacity were observed during the occipital stimulation trial and during the 3-mo follow-up after implantation. The mean VAS score changed from 8.66 +/- 1.0 to 2.5 +/- 1.3 whereas pain disability index improved from 49.8 +/- 15.9 to 14.0 +/- 7.4. Our midline approach has several advantages compared with the submastoid approach used elsewhere. There is only one small midline incision over the upper neck and the strain on the lead extension occurs only with flexion and is minimal with lateral flexion and rotation, which contributes to overall stability of this system.

    ABSTRACT: Cervicogenic headache (CGH) is defined as referred pain from various cervical structures innervated by the upper three cervical spinal nerves. Such structures are potential pain generators, and include the atlanto-occipital joint, atlantoaxial joint, C2-3 zygapophysial joint, C2-3 intervertebral disc, cervical myofascial trigger points, as well as the cervical spinal nerves. Various interventional techniques, including cervical epidural steroid injection (CESI), have been proposed to treat this disorder. And while steroids administered by cervical epidural injection have been used in clinical practice to provide anti-inflammatory and analgesic effects that may alleviate pain in patients with CGH, the use of CESI in the diagnosis and treatment of CGH remains controversial. This article describes the neuroanatomy, neurophysiology, and classification of CGH as well as a review of the available literature describing CESI as treatment for this debilitating condition.

    ABSTRACT: Peripheral nerve stimulation and peripheral nerve field stimulation are emerging as a viable neuromodulatory therapy in the treatment of refractory pain. Although the technology of percutaneous stimulation has been available for decades, recent advancements have broadened the number of indications. Success of treatment revolves around identifying the correct patient population, and the selection and placement of the appropriate electrodes and implantable pulse generators. Most results to date have come from case reports and retrospective studies. However, given the promising outcomes in reducing otherwise medically refractory pain, future randomized controlled studies are needed to assess this emerging technology.

    ABSTRACT: Patients with medically refractory headache disorders are a rare and challenging-to-treat group. The introduction of peripheral neurostimulation (PNS) has offered a new avenue of treatment for patients who are appropriate surgical candidates. The utility of PNS for headache management is actively debated. Preliminary reports suggested that 60-80% of patients with chronic headache who have failed maximum medical therapy respond to PNS. However, complications rates for PNS are high. Recent publication of 2 large randomized clinical trials with conflicting results has underscored the need for further research and careful patient counseling. In this review, we summarize the current evidence for PNS in treatment of chronic migraine, trigeminal autonomic cephalagias and occipital neuralgia, and other secondary headache disorders.
