If the foramen ovale lies mediallyfrom the foramen Civinini, then the transverse way (from beneath the 536 LOCAL ANESTHESIA zygomatic arch) must first go through the foramen Civinini in orderto reach the nervus mandibularis, which in practice must involvedifficulties. Likewise the way from in front through the cheek ormouth can be obstructed by an ossified ligamentum pterygospinosumaccompanied by narrowness of the foramen ovale. However, we havefound this relationship only once among 134 examinations (Table II,No. 3), while we observed the ossification itself 9 times (7 percent). The distance of the poste
