[Hyoglossal balance and vertical morphogenesis of the 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.
