Infraorbital nerve block is used for intraoperative and postoperative analgesia in nasal and oral surgery procedures, as well as in the chronic pain settings. Ultrasound guidance has not been described in the literature. The aim of the study was to assess the quality of ultrasound imaging of the infraorbital foramen and develop an "in-plane" technique of the block using a skull model. ⋯ This experimental study suggests that the infraorbital foramen is easily located using ultrasound and an "in-plane" ultrasound-guided technique for infraorbital nerve blockade is feasible on the model.
