INTRODUCTION: Infiltration of the greater occipital nerve (GON) with local anaesthetics and corticosteroids is a treatment option for cluster headache.

METHODS: We retrospectively analysed the efficacy and safety of 121 GON injections in 60 patients with episodic or chronic cluster headache over a period of 4 years.

RESULTS: Almost 80% of the infiltrations were at least partially effective (reduction of attack frequency, duration or severity) and 45% resulted in a complete response (no further attacks). The effect was maintained for 3.5 weeks on average in chronic cluster headache. In episodic cluster headache, the effect lasted for most of the bout. In 18 infiltrations, transient side effects were reported, such as local pain, steroid effects (facial oedema, sleeping disorders, acne), bradycardia or syncope.

CONCLUSION: Our data show that GON infiltration is a valuable and safe option in the clinical setting to treat patients suffering from cluster headache, especially for the episodic form of the disorder.
