Decompression of the greater occipital nerve improves outcome in patients with chronic headache and neck pain - a retrospective cohort study

Background Compression of the greater occipital nerve (GON) may contribute to chronic headache, neck pain, and migraine in a subset of patients. We aimed to evaluate whether GON decompression could reduce pain and improve quality of life in patients with occipital neuralgia and chronic headache and neck pain. Methods In this retrospective cohort study, selected patients with neck pain and headache referred to a single neurosurgical center were analyzed. Patients (n = 22) with suspected GON neuralgia based on nerve block or clinical criteria were included. All patients presented with occipital pain spreading frontally and to the neck in various degree. Surgical decompression was performed under local anesthesia. Follow-up was made by an assessor not involved in the treatment of the patients, by telephone 2-5 years after the surgical procedure and an interview protocol was used to collect information. The data from the follow-up protocols were then analyzed and reported. Results When analyzing the follow-up protocols, decreased headache/migraine was reported in 77% and neck pain was reduced in 55% of the patients. Conclusions Decompression of GON(s) may reduce neck pain and headache in selected patients with persistent headache, neck pain, and clinical signs of GON neuralgia. Based on the limitations of the present retrospective study, the results should be considered with caution.
