Outline of Final Research Achievements

Age-related muscle loss also occurs in the muscles around the mouth, as well as the skeletal muscles of the body. The supra-hyoid muscles which attached to the mandible and hyoid bone, pulls the hyoid bone up, then the epiglottis covers the trachea during swallowing phase so that food does not enter the lungs. It is supposed that the maxillofacial skeleton might be related to swallowing performance. The aim of this study is to clarify the skeletal factors that affect swallowing with cephalometric and statistics analysis. The results showed that the mandibular anteroposterior position may be related to swallowing performance.
