HEADACHE, Issue 10 2008

Objective., To determine the efficacy of occipital nerve blocks using reconstituted botulinum toxin type-A (BTX-A) in providing significant and prolonged pain relief in chronic occipital neuralgia. Background., Occipital neuralgia is a unilateral or bilateral radiating pain with paresthesias commonly manifesting as paroxysmal episodes and involving the occipital and parietal regions. Common causes of occipital neuralgia include irritation or injury to the divisions of the occipital nerve, myofascial spasm, and focal entrapment of the occipital nerve. Treatment options include medication therapy, occipital nerve blocks, and surgical techniques. BTX-A, which has shown promise in relief of other headache types, may prove a viable therapeutic option for occipital neuralgia pain. Methods., Botulinum toxin type-A (reconstituted in 3 cc of saline) was injected into regions traversed by the greater and lesser occipital nerve in 6 subjects diagnosed with occipital neuralgia. Subjects were instructed to report their daily pain level (on a visual analog pain scale), their ability to perform daily activities (on several quality of life instruments) and their daily pain medication usage (based on a self-reported log), 2 weeks prior to the injection therapy and 12 weeks following injection therapy. Data were analyzed for significant variation from baseline values. Results., The dull/aching and pin/needles types of pain reported by the subjects did not show a statistically significant improvement during the trial period. The sharp/shooting type of pain, however, showed improvement during most of the trial period except weeks 3-4 and 5-6. The quality of life measures exhibited some improvement. The headache-specific quality of life measure showed significant improvement by 6 weeks which continued through week 12. The general health- and depression-related measures showed no statistical improvement. No significant reduction in pain medication usage was demonstrated. Conclusions., Our results indicate that BTX-A improved the sharp/shooting type of pain most commonly known to be associated with occipital neuralgia. Additionally, the quality of life measures assessing burden and long-term impact of the headaches, further corroborated improvement seen in daily head pain. [source]


Occipital Nerve Blocks: Effect of Symptomatic Medication

HEADACHE, Issue 10 2009
Headache Type on Failure Rate, Overuse
Objective., To explore the effect of symptomatic medication overuse (SMO) and headache type on occipital nerve block (ONB) efficacy. Methods., We conducted a chart review of all of the ONBs performed in our clinic over a 2-year period. Results., Of 108 ONBs with follow-up data, ONB failed in 22% of injections overall. Of the other 78%, the mean decrease in head pain was 83%, and the benefit lasted a mean of 6.6 weeks. Failure rate without SMO was 16% overall, and with SMO was 44% overall (P < .000). In those who did respond, overall magnitude and duration of response did not differ between those with and those without SMO. Without SMO, ONB failure rate was 0% for postconcussive syndrome, 14% for occipital neuralgia, 11% for non-intractable migraine, and 39% for intractable migraine. With SMO, failure rate increased by 24% (P = .14) in occipital neuralgia, by 36% (P = .08) for all migraine, and by 52% (P = .04) for non-intractable migraine. Conclusions., SMO tripled the risk of ONB failure, possibly because medication overuse headache does not respond to ONB. SMO increased ONB failure rate more in migraineurs than in those with occipital neuralgia, possibly because migraineurs are particularly susceptible to medication overuse headache. This effect was much more pronounced in non-intractable migraineurs than in intractable migraineurs. [source]

(615) Combined Use of Cervical Spinal Cord Stimulator (SCS) and Occipital Nerve Stimulator (ONS)

PAIN MEDICINE, Issue 2 2000
Article first published online: 25 DEC 200
Author: Y. Eugene Mironer, Carolinas Center for Advanced Management of Pain A 51-year-old female patient was referred to the clinic in March 1997 with severe cervicalgia and right shoulder girdle pain. She rated her pain at 9/10 on a Visual Analog Scale (VAS). MRI showed multilevel severe spondylosis with significant neural foraminal stenosis at 3 levels. Multiple modalities of treatment (physiotherapy, epidural steroid injections, cervical plexus blocks) and a variety of medications (opioids, NSAIDs, anticonvulsants, antidepressants, etc.) failed to provide any improvement. The patient twice consulted neurosurgeons but was considered a poor surgical candidate. Finally, in July 1997, after a successful trial, a cervical SCS was implanted with the tip of the lead at level C2, achieving excellent coverage of the pain area. For the next 18 months the patient continued to do well, having minimal neck and shoulder discomfort and using only occasional oral analgesics. However, by January 1999, she developed intractable right-sided occipital neuralgia. Occipital nerve blocks were providing extremely short-term relief and the intake of different analgesics, including opioids, started to increase. In March 1999, after successful trial, an ONS was implanted. Unfortunately, it migrated shortly after implantation and had to be revised and re-anchored. After this procedure all headaches were completely controlled without medications. The patient continues to be very active, uses both stimulators daily, does not take any analgesics and rates her pain at 0/10 to 1/10 on VAS. [source]
