[Variation in the lateral plate of the pterygoid process and the lateral subzygomatic approach to the mandibular nerve].

Abstract

While applying conductive anaesthesia on mandibular nerve by lateral subzygomatic route, variable ossificated formations at lateral plate's posterior border of pterygoid process should be kept in mind. It is possible that a needle, at a depth of 35 mm, comes across incompletely or completely ossificated lig. pterygospinale et crotaphitico-bucciantorium. Based on ours anatomy research we concluded that these formations are more oftenly present on males aged over 50, and that one-sided presence is more often on the left side. Ossificated formations which were the object of our research are not an obstacle to high-quality applying of conductive anaesthesia on trigeminale ganglion et mandibular nerve each time when they exist, but only when they are located laterally from foramen ovale, what appeared at 12 sculls (3.93%) in our case.
