Brief Summary
Cluster headache (CH) is the most common of the trigeminal autonomic cephalalgias and one of the most severe pains known to man, having a large impact on the sufferer's quality of life. A parasympathetic dysfunction in CH has been suggested. The sphenopalatine ganglion has been a target for treatment of primary headache disorders for more than a century but there are several anatomic and physiologic studies that suggest that another cranial parasympathetic ganglion, the otic ganglion (OG), might be also relevant in CH. In this study OG will be blocked with botulinum toxin type A in a pilot study in 10 patients with chronic cluster headache. Recruitment of patients will be solely in Norway. There is no data available to determine the correct dosage of botulinum toxin. A similar neural structure that has been blocked with botulinum toxin in humans is the sphenopalatine ganglion. The investigators injected 10 patients suffering from intractable chronic cluster headache with botulinum toxin in the sphenopalatine ganglion. 5 patients were given 25 IU and 5 patients were given 50 IU. Even though the number of treated patients is low, there did not appear to be differences in the adverse events profile between those who received 25 Iu and those who received 50 IU. The investigators also previously injected 25 IU botulinum toxin towards the sphenopalatine ganglion bilaterally (i.e. 25 IU in each side) in 10 patients suffering from intractable chronic migraine. Doses of up to 25 IU have been injected in structures adjacent to the otic ganglion, for instance in dystonia towards the lateral pterygoid muscle. Thus it was decided for this study on injection towards the otic ganglion, to explore the safety of 12.5 and 25 IU of botulinum toxin.

Outcome Measures
Primary Outcomes (1)
Number of adverse events (AE)
All adverse events will be registered. The likelihood of a relationship between the AE and the pharmacological substance or the procedure will be evaluated. Data will be collected from the headache diary (free text) and open questions at the office follow up visits.
for the follow-up period of 6 months
Secondary Outcomes (12)
Number of cluster headache attacks per week
for the follow-up period of 6 months
Duration of cluster headache attacks
for the follow-up period of 6 months
Days without cluster headache attacks
for the follow-up period of 6 months
Headache intensity on a 0-5 scale
for the follow-up period of 6 months
Mean intensity per attack
for the follow-up period of 6 months
- +7 more secondary outcomes
Study Arms (2)
Botulinum Toxin 25 IU
EXPERIMENTAL5 patients will be injected with 25 IU of Botulinum Toxin Type A towards the otic ganglion in the symptomatic side (ipsilateral to the pain)
Botulinum Toxin 12.5 IU
EXPERIMENTAL5 patients will be injected with 12.5 IU of Botulinum Toxin Type A towards the otic ganglion in the symptomatic side (ipsilateral to the pain)
Interventions
injection with 25 IU botulinum toxin towards the otic ganglion (symptomatic side) using image-guided navigation and the MultiGuide device
injection with 12.5 IU botulinum toxin towards the otic ganglion (symptomatic side) using image-guided navigation and the MultiGuide device

You may qualify if:
- Informed and written consent
- Fulfilling International Classification of Headache Disorders (ICHD) -3 Beta criteria for chronic cluster headache
- Mean attack frequency of four attacks per week or more
- Agreeing to refrain from starting new prophylactic cluster headache medication, including steroids, or any other therapy aimed at cluster headache, and agreeing to maintain existing prophylactic cluster headache medication from 4 weeks before entering the baseline period throughout the duration of the study
- Intractable cluster headache, i.e. unsatisfactory effect, intolerable side effects or contraindication of at least 2 of the following medications: Verapamil, Lithium, Suboccipital steroid injection,
- Able to distinguish between cluster headache attacks and other types of headache.
