Marston AP, et al. - This research was conducted with the intention of better defining the impact of pediatric facial skeletal growth on techniques for accessing the pterygopalatine fossa (PPF). A substantial rise was noted in the distance from the skin to the foramen rotundum with age. Nonetheless, the angles of re-orientation with respect to the original needle entry site illustrated up to only 3° of variability between the youngest and oldest age groups examined in this pediatric cohort.
