[Cauhépé-Fieux syndrome. Interception in the deciduous dentition of mid-face hypoplasia].

Inadequate transverse development of the milk dentition alveolar arcade (Cauhepe-Fieux syndrome) may have important effects on the constitution of facial architecture and in the medium term require orthognathic surgery. The acquisition of dental arcade contact on deglutition is only possible after normalization of the dimensions of the arch of the palate. The recommended suture inducing prosthesis should obligatorily include intercalating molar plates designed to overcome inadequate occlusion during treatment (on average 9 months). Both stimulation of growth at the level of the intermaxillary suture in this age group, and the stability of the results obtained, have been demonstrated after a period of follow up of more than 10 years taking into account the cybernetic aspects of the studies carried out by Professor Petrovic.

[Mandibular angle and orthodontic treatment. Apropos of the possible therapeutic inversion of the direction of rotation of mandibular growth].

The spontaneous and therapeutic modifications of the mandibular angle suggest that the rotations of growth described by Björk are not inevitable but are due to lingual dysfunction, particularly involving the pharyngeal part. Adequate treatment can modify the widening and narrowing of this angle.

[Facial profile--psychological profile].

The morphological organisation of the face reflects the individual's social context and heredity and also reveal certain personality traits. Emotional facial expression is a very special form of communication. This functional and behavioural dynamic leads to the formation of a certain anatomical structure as a result of repetitive functions. The psychological examination of nineteen retrognathic patients and seven prognathic patients revealed the timid, inhibited of even anxious personality of the first group of patients in contrast with the extraverted and frequently aggressive personality of prognathic patients.

[Lingual vascular malformations, their consequences on the growth of the inferior facial plane. The integration of orthodontic embolization].

Lingual vascular malformations are usually benign, but have repercussions on the growth of the maxillo-mandibular unit in the child. The improvement in the vascular problems at puberty leads the authors to prefer a conservative form of treatment, hence the important role of embolization techniques. These techniques should be followed by the fitting of a lingual guide appliance, similar to the "mono-block" designed by Pierre Robin. This orthesis forces the child to modify incorrect movements due to the volume of the angiomatous tongue and gradually teaches him to automatize the new motor images created based on the dynamics of a virtually normal tongue, within the 6 months following embolization.

["Renal dwarfism". Its impact on dental development and on maxillary growth].

Children with terminal renal failure require iterative dialysis while awaiting kidney graft, and these have to be repeated over a period of years until a suitable graft presenting histocompatibility with the receiver is found. This has a considerable growth retardation effect (-3 to -6 SD, according to the age at onset of terminal failure). Two features appear to be paradoxical in these children. 1) In spite of a high carbohydrate diet and generally poor oral hygiene, they present a low prevalence of caries, probably related to modified salivary components. The only objective finding is an increase in salivary urea levels. 2) In spite of harmonious hypotrophy, no particular encumbrance of the dental arch is observed. Alveolar growth, contemporary with dental eruption, is sufficient to compensate possible hypotrophy of maxillary bone bases.
