Usefulness of large palatine nerve block for trigeminal neuralgia

Abstract

Objective: We report cases of trigeminal neuralgia that was difficult to treat with medication or other nerve block therapy. Methods: Five patients with trigeminal neuralgia of the second branch of the trigeminal nerve all had inadequate response to medical treatment. 4 patients had difficulty with Gasserian ganglion block or had residual pain even when it could be performed. 1 patient initially opted for large palatine nerve block. Infraorbital nerve block was used in all patients. Results: Compared with fluoroscopic nerve blocks such as Gasserian ganglion block, palatine nerve block is a simple procedure with less invasion and pain for patients. In all patients, the pain disappeared for more than 1 year.
