Aim. To examine the anatomical and radiological features of mental area of the mandible. Material and Methods. In the course of this anatomical study was made craniometric measurement of 50 corpses, aged 18-70 years without maxillofacial pathology. For histological research were taken neurovascular bundle length of 0.1-0.2 cm of the channel region of mental spine (MS). The material was impregnated with silver nitrate by Christensen. Results and Discussion. As a result of anatomical and radiological examinations were found 3 types of mental spine channels. I type: a narrow channel having a main direction of the mouth opening and MS down the center of the mandible projection falling into the channel of intraosseous part of the mental nerve; II type: channel having a wavy line from the mouth of the hole MS and down to the center of the mandible, perforating channel of intraosseous part of the mental nerve; III type: crumbly channel having a main direction from the MS foramen and chin pronounced curvature in the lower third, projecting of the envelope channel intraosseous part of the mental nerve. Histological confirmed presence of nerve fibers in the composition of the bundle passing in the canal of the mental spine. Conclusions. The presence of a system of canals in the chin awn containing thin nerves is proved. Based on the pilot study, it is possible to predict the relationship between the type of the skull and the shape of the channels.
