Though its effect on pain is understood to be primarily peripheral, via the decreased release of neurotransmitters, recent evidence supports an additional central mechanism. OnabotulinumtoxinA (ONA), commonly known by the brand name Botox, has been utilized in nerve blocks to treat a variety of neuropathic pain syndromes, including chronic migraine.

Anesthetic nerve blocks are used for diagnosis and treatment of occipital neuralgia, but treatments with the potential for longer-term relief, including nerve stimulation, pulsed radiofrequency, cryoablation, C2 ganglion decompression, and botulinum toxin have recently been utilized. While usually idiopathic, occipital neuralgia is a common form of posttraumatic headache, and is also associated with the elderly population, postoperative complications, vascular compression, and infectious diseases. Tenderness and trigger points in the distribution of the affected nerves are characteristically present. The pain is typically severe and shooting, stabbing, or sharp in quality. Occipital neuralgia is characterized by unilateral or bilateral pain in the distribution of the greater, lesser, and/or third occipital nerves. Received 7 April 2016 accepted 5 July 2016 published 8 July 2016 Our results support the hypothesis that use of Onabotulinum-toxinA in occipital nerve blocks leads to significant decreases in pain, while possibly exhibiting a longer duration of action than that of local anesthetic. Opioid use did not exhibit significant change, regardless of treatment type. Treatment with local anesthetic suggested equally efficacious reduction of VAS scores however, treatment with ONA showed a significantly higher percentage of overall pain relief leading to follow-up.

Patients treated with ONA exhibited significant decreases in average VAS pain scores from 4.1 ± 2.6 pre-procedure to 2.1 ± 2.4 post-procedure (p = 2 × 10 -5), and 3.0 ± 2.5 4 weeks later (p = 0.0234).

Information on opioid use, overall pain relief, and duration of full relief was also recorded upon follow-up. Patients reported VAS pain scores before and after their procedures, and again during 4-week follow-up visits.

A total of 61 patients, including 17 of those subsequently treated with ONA, were treated with local anesthetic, using a 1:1 mixture of 0.25% bupivacaine and 1% lidocaine, plus triamcinolone.

80 - 155 units of ONA were administered bilaterally in the surrounding musculature. Our study retrospectively examined 63 patients treated for occipital neuralgia, including 19 with ONA. OnabotulinumtoxinA (ONA) has recently been utilized in nerve blocks to treat occipital neuralgia, with the potential for a longer duration of pain relief than local anesthetic. Typical treatments include nerve blocks with local anesthetic, nerve stimulation, pulsed radiofrequency, and cryoablation. Occipital neuralgia is typically idiopathic, but also is characterized as a common form of posttraumatic headache. Occipital neuralgia is characterized by severe pain, accompanied by tenderness and trigger points, in the distribution of the greater, lesser, and/or third occipital nerves.
