The medical records of these patients between January 13, 2016 and August 25, 2021 were retrieved, and the patients were followed up for 6 months. Follow-up outcomes were Numerical Rating Scale (NRS) scores, medications and dosage. The effective rate was defined as the number of cases with NRS score reduction of > 50%/total number of cases× 100% at 12 weeks postoperatively.Results: The postoperative NRS scores were significantly decreased in all patients (P 50% was 56.4% and the effective rate was 66.7% in all patients, at 3 months after the block treatment. There was no significant difference in the reduction of medication use value of > 50% and the effective rates between the two groups. There were no intracranial hemorrhage, infection or other serious adverse effects in either groups.Conclusion: CT-guided gasserian ganglion block with local anesthetics and steroids can be an effective and safe technique to relieve the pain of acute/subacute zoster-related trigeminal neuralgia.Keywords: acute/subacute zoster-related trigeminal neuralgia, gasserian ganglion block, local anesthetics, steroids, multicenter retrospective study
