In the present study, we investigated the influence of function of musculi suprahyoidei to facial pattern. Subjects consisted of 67 Japanese males. Lateral cephalograms were taken for each subjects. So the relation between the position of hyoid bone and cranium viscerale was studied. The findings were as follows. 1. The higher the hyoid bone to SN was, the more posterior the facial pattern was. The lower the hyoid bone to SN was, the more anterior the facial pattern was. 2. The higher the hyoid bone was, the more posterior the points A, B and Pog. to SN were. The maxilla and mandible tended to be in a retruded position. 3. As the hyoid bone was higher, ∠SN-Ar・G was more increased and ∠SN-NF, ∠SN-Occ and ∠SN-Mp were more increased. Mandibular plane tended to be steep. The results suggested that maxillofacial pattern was correlated with hyoid bone. Therefore, maxillofacial pattern must be grasped from the functional aspect of musculi suprahyoidei and musculi infrahyoidei.
