The oral zone reflects the relational modalities of the child: the sensorimotor physiological and psychological behaviour is established according to the development of the facial sphere and its aero-digestive crossroads. In the baby, the mandibular equilibrium and position and the dimensions of the lower part of the face essentially depend upon praxic activities, which drive the mandibular and hyoid displacements. During the period of immaturity, the lingual area is brought into movement with each "sucking-swallowing" action that characterises breast-feeding: the mandibulo-hyoid swing is subordinate to the pharyngo-lingual complex. The analysis of this psycho-motor behaviour reveals imperfect and upsetting "mimics" that modify the balance of the jaw and of the hyo-lingual area during swallowing, which is the second phase of the reassurance breast-feed. The lingual ptosis causes congestion of the airways. These lax children, with a receding chin, are deformed by their oral habits. The clinical picture evidences the constitutional hyperlaxity by examining the parental group -the same facial dystrophies, the same habits resulting in various disorders of general or cervical statics. At the level of the temporomandibular joint, the dysfunction is also accompanied by claudication by mandibulo-hyo-lingual tipping. The general and cervical statics of the baby are thus affected in the course of sleep. It is during paradoxical sleep that the baby's head tips on to the thorax, due to the resultant atonia of the neck muscles. The head, insufficiently supported on its cervical pillar accentuates the asphyxial mechanism provoked by the tipping of the lingual area on the epiglottis.(ABSTRACT TRUNCATED AT 250 WORDS)
