[Morphogenetic role of the trigeminal nerve. A new approach to facial architecture]. / Rôle morphogénétique du nerf trijumeau. Une approche nouvelle de l'architecture faciale.

Trigeminal nerve acts a main part in morphogenesis and facial pattern. Its contribution to skeletal building and fibrous distribution according to those of different anatomo-functional matrixes allow a radiographic approach of the mesofacial morphology. Excluding anterior exofacial structures, the first statistical results lays the foundations of an accurate and promising architectural cephalometric analysis of mesofacial part.

[Facial aging. The evolution of the soft tissues]. / Contribution à l'étude du vieillissement facial. Evolution des tissus mous.

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.

[Functional hierarchy and mandibular esthetics]. / Hiérarchie fonctionnelle et esthétique mandibulaire.

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?

[Craniofacial anatomo-morphological profile of black African Ivory Coast children]. / Recherche d'un profil anatomo-morphologique cranio-facial de l'enfant ivoirien de type negro-africain.

An African Negroïd ivorian child's facial, cranial, morphological and anatomical profile research The cephalometric study of telerdiography negatives of profile carried out on a sample of 52 Ivorian children from 11 to 14 years old, has shown some particularities which characterize the face and skull architecture. These particular features differentiate the Ivorian from the west Africans and from the French. According to the authors it would be better to establish the Ivorian's specific norms and to consequently adapt the face and tooth orthopedie therapeuties.

[Hyoglossal balance and vertical morphogenesis of the face]. / Equilibre hyo-lingual et morphogenèse verticale de la face.

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.
