title: The groove of the mandibular neck as a risk factor in vertical osteotomy of the ramus of the mandible.
abstract: Surgical damage of anatomical structures within the mandibular canal represents one of the risks of dysgnathia operations performed on the ramus of the mandible. The paper presents a review of the various measurements of anatomical landmarks available in the pertinent literature. The occurrence of the sulcus coli mandibulae, as well as the depth of the groove have been studied. In some cases the groove has to be considered as a surgical risk factor. On the basis of the examination, attention is called to the individual variations and to the necessity of a cautious surgical technique.
