Cluster headache is a primary headache condition characterized by clusters of one-sided, high-intensity pain attacks. The headache may be episodic or chronic. Treatment options are limited and their effects unsatisfactory. An important nerve pathway involved in the pain attacks has a switching station at the sphenopalatine ganglion (SPG) located in the depth of the facial bones. SPG is a known therapy target for cluster headache. The area can be identified on CT images, but is difficult to access due to its location. Thus, the Multiguide navigation system has been developed to enable precise delivery of the drugs that target SPG activity. In Trondheim, two phase 1 / Phase 2 study have been carried out using botulinum toxin A (Botox®) against SPG in patient with chronic cluster headache and chronic migraine. The results indicate that such a treatment strategy is safe and beneficial. The current study is a randomized, placebo-controlled, triple-blinded study to investigate whether precise single-injection of botulinum toxin A reduces the frequency of attacks in chronic cluster headache .

Subject has undergone facial surgery in the area of the pterygopalatine fossa or zygomaticomaxillary buttress ipsilateral to the planned injection site that, in the opinion of the Investigator, may lead to an inability to properly conduct the procedure.
Facial anomaly or trauma which renders the procedure difficult.2
Subject currently has an active oral or dental abscess or a local infection at the site of injection based on present symptoms.
Subject has been diagnosed with any major infectious processes such as osteomyelitis, or primary or secondary malignancies involving the face that have been active or required treatment in the past 6 months.
Patients exhibiting a high degree of comorbidity and/or frailty associated with reduced life expectancy or high likelihood of hospitalization, at the discretion of the investigator.
Patients with comorbid psychiatric disorders with psychotic or other symptoms making compliance with the study protocol difficult, at the discretion of the investigator.
Patient with active infectious disease or infections that warrants special infection control measures, such as human immunodeficiency virus, tuberculosis, or chronic hepatitis B or C infection.
Patient with disorders that are known contraindication for Botox® treatment, especially neuromuscular disorders such as motorneuron disorders and myasthenic syndromes
Subject has had previous radiofrequency ablation, balloon compression, gamma knife, or chemical denervation (e.g. glycerol treatments) of the ipsilateral trigeminal ganglion or any branch of the trigeminal nerve.
Subject has had previous radiofrequency ablation (including non-lesional pulsed radiofrequency), balloon compression, gamma knife, or chemical denervation (e.g. glycerol treatments) of the ipsilateral SPG.
Subject has had blocks of short-acting anaesthetics of the ipsilateral SPG in the last 3 months.
Subject has undergone onabotulinumtoxinA injections of the head and/or neck in the last 3 months.
Subject is anticipated to require any excluded medication, device, or procedure during the study.
Subject has a history of bleeding disorders and in the opinion of the Investigator, may lead to an inability to properly conduct the procedure.
Subject has a history of coagulopathy.
Subject is unable to stop antithrombotic medication, eg. anticoagulants and/or antiplatelet therapy, before procedure.
The subject has been diagnosed with another trigeminal autonomic cephalalgia or trigeminal neuralgia.
The patient cannot participate or successfully complete the study, in the opinion of their healthcare provider or the investigator, for any of the following reasons:
The patient is a study centre employee who is directly involved in the study or the relative of such an employee.
