Fig. 6. Application of virtual simulation in performing the Gasserian ganglion block. (A, B) Three-dimensional virtual procedural planning. The virtual needle is placed at the most appropriate position with reference to the right foramen ovale. (C) Caudal tilted anteroposterior view of the virtual X-ray image is saved where the needle presented as a pinpoint. (D) Lateral view of the simulated virtual X-ray. (E) The patient’s X-ray image in the caudal tilted anteroposterior view during the procedure. (F) The patient’s X-ray image in the lateral view during the procedure.
