Abstract
Some anatomical variations make often a successful conduction anaesthesia of the ganglion semilunare Gasseri and of the mandibular nerve in the region of the oval foramen impossible. In blockage by the extraoral i. e. by the lateral subzygomatic way the ossified ligaments in the region of the oval foramen: the ligamentum pterygospinale Civinini and the ligamentum crotaphitico-buccinatorium Hyrtl may cause an obstacle. The authors have investigated on 530 macerated skulls the frequency of development of these ligaments i. e. the formation of the foramen pterygospinale and of the foramen crotaphitico-buccinatorium. They have established that these foramina are more often developped than it is cited in the literature. The incomplete foramen pterygospinale was present in 7,64% of case and the complet foramen in 3,96% of cases. The incomplete foramen crotaphitico-buccinatorium was present in 4,90% of cases and the complete foramen in 2,55% of cases. The authors point out finally that the existance of the incomplete and especially of the complete foramen crotaphitico-buccinatorium can be an obstacle to conduction anaesthesia which should always be kept in mind.
