Abstract

The musculus masseter, ensuring movements of the mandible, displace the osseous pieces at its fracture up/down in the lateral and medial sides. Morphometrical investigation of the musculi depressores++ mandibulae has been performed. As a whole 33 corpses (29-78 years of age) of normosthenic++ complexion have been studied. The measurements have been performed by means of a special compasses and a ruler with an approximation to 1 mm and 1 degree. The length of the digastric muscle belly is 55.3 +/- 1.1 mm. The length of the geniohyoid muscle is 44.5 +/- 0.9 mm. The distance between the centers, where the digastric muscle are fixed on the hypoglossal bone is 46.1 +/- 1.1 mm, and on the mandible--25 +/- 9 mm. The width of fixation of the musculus mylohyoideus on the mandible is 52.6 +/- 1.2 mm. The angles between the masseter muscles, the mandibular body and the occlusive plane have also been determined.
