Ageing of the face is one of the most apparent. Face varies in shape and aspect. The reasons of these modifications are various: skin ageing, lost of teeth, changes in facial skeleton and modifications of the whole facial soft tissues. Soft tissues evolution in mentalis and anterior nasal spin regions was studied on a 206, 21 to 101 years old subjects population. It was shown that in both men and women samples the soft tissues thickness increase in the mentalis region and decrease in that of anterior nasal spin.

Is the balance of the hyo-lingual musculature very important about mandibular morphology and orientation of mandibular growth? The purpose of this study is to detect the existence of possible reports between hyo-lingual position and mandibular morphogenesis. The selected population is made of fifty children from eight and a half to ten and a half years old, who are thumb sucking and mouth breathing. The means of study are norma lateralis teleradiographs made when facial musculature is at rest position. The statistical analysis implies a descriptive and correlative analysis of 82 variables, and a comparative study with an other sample. In spite of anatomic bonds, it seems to be a relative independence between lingual morphology and orientation of mandibular growth. Perhaps head posture is it a more important mechanism!

The purpose of the present study based on the comparison of two populations showing a different average of age, was to see the possible action of the tongue on the mandibular morphology. This study included the examination of norma lateralis teleradiographs, while both facial and lingual musculatures were in rest position. If it appears that older subjects show a close correlation between mandibular divergence and lingual height, this relation doesn't take place in younger subjects although they present an earlier mandibular hyperdivergence. May breathing, a function hierarchically of the highest importance be more determinant in lower face organisation than deglutition and lingual equilibrium?

The purpose of this study is to detect the existence of eventual relations between position and dimensions of tongue and pharynx soft tissues and vertical growth of face. The population is made up of 50 children of 9 to 11 years old with sucking habits and difficulties in breathing. The documents are teleradiographies in norma lateralis made when the patient is in rest position. This study expounds vertical facial characteristics of this population through a statistical descriptive analysis and then through a correlative approach of those characteristics and some soft tissues measurements.
