Ganglion impar block is a safe and useful treatment for chronic sympathetic pain in the anal region. The current ganglion impar block methods include the curved needle approach from the tip of the coccyx, the vertical approach from the sacrococcygeal or intercoccygeal region, and the lateral (parasacrococcygeal) approach. This article describes the lateral approach.
