- 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.

- BACKGROUND: Trigeminal neuralgia (TN), a severe type of facial pain, is mainly caused by a neurovascular conflict (NVC). The severity of the NVC seems associated with the outcome following microvascular decompression (MVD) surgery. This study aimed to investigate the outcome after MVD and whether it is affected by NVC severity and sex.METHODS: TN patients (n = 109) were followed for 5 to 10 years after MVD. Barrow Neurology Index (BNI), Patients Global Impression of Change (PGIC), complications, and time to relapse were evaluated. The NVC severity was retrospectively reviewed from presurgical MRI. Demographic and clinical factors and NVC severity were analyzed for potential association with outcome after MVD.RESULTS: The success rate (BNI ≤ 2) was 80% after 5 to 10 years follow-up for TN patients with severe NVC (grade 2-3) and 56% for TN patients with mild NVC (grade 0-1, P = 0.003). No sex difference was observed in outcome for patients with both mild (P = 0.924) and severe NVC (P = 0.883) respectively. Three patients (2.8%) during the hospital stay, and two patients (1.8%) at 6 weeks, experienced a complication requiring invasive treatment. At long-term 52/109 patients (47.7%) reported some type of persistent adverse event, of which the majority were mild and required no treatment.CONCLUSIONS: MVD offers an 80% probability of long-term pain relief in TN patients with severe NVC, with low frequency of serious complications. NVC severity significantly affects outcome after MVD, while no sex differences in outcome were found. In consistency with previous work, the results stress the importance of adequate neuroradiological assessment of the NVC for preoperative patient selection.
