[Radiographic anomalies and obstructive sleep apnea syndrome].

BACKGROUND: The purpose of this study was to identify the particular cranio-facial pattern observed in patients with obstructive sleep apnea syndrome and to search for possible correlations between morphological anomalies and disease severity. MATERIAL AND METHODS: The study group included 49 dentate patients, mean age 47.7 years suffering from obstructive sleep apnea syndrome. Most of the patients were overweight. RESULTS: Typical features observed in these patients were a short craniospinal field, a retro-maxillary, a retro-mandibula, antero-inferior vertical excess of the face, and class II malocclusion. No correlation between severity of obstructive sleep apnea syndrome and craniofacial morphology could be identified. DISCUSSION: These results are in agreement with data in the literature. The absence of a morphological correlation appears to be related to the type of patients studied (overweight). Indeed, two categories of sleep apnea patients have been identified: obese patients who have few or no anomalies of the facial skeleton and thin patients with characteristic open bite class II malocclusion.

[The management of anterior transversal mandibular deficiencies by distraction osteogenesis. Preliminary results and report of 3 cases].

During the last ten years, osteodistraction genesis appeared as being a treatment of some maxillo-facial transversal deficiencies. A new technique have been develop in Lille Maxillo-Facial Department (Pr Ferri, France). This new technique is used in cases of mandibular hyposymphysis, which induce most of the time a mandibular incisor crowding. This distraction osteogenesis performed after sagittal osteotomy of the mandibular symphysis and associated with orthodontic treatment is a solution to avoid teeth extractions. Other treatments could be used to solve anterior mandibular teeth crowding but they have disadvantages: teeth slicing, teeth extraction or orthodontic teeth tilting. This new technique is performed with intra oral-device, small enough to be placed under mandibular periosteum. Three patients have been treated by this technique, they got a stable result. In these three cases, alveolar and basal bone is present. So for us, symphysis osteogenesis distraction appears to be an alternative treatments to mandibular incisor crowding.

[Growth: responses to pathology. Preliminary study].

Many pathologies involve face. Among them, many have craniofacial growth consequences. The authors' aims are to analyze some of these pathologies, where clinical observations emphasize the role of the different craniofacial growth patterns. Despite a complex relation between the malformative part and the deformative one, untreated observations provide a better understanding of some craniofacial growth defects. Syndromes can be classified in 4 categories, involving the primitive causes of the clinical finding: 1. organic abnormalities of one or many functional matrix, 2. localized abnormalities of the anatomical structures, 3. general abnormalities of the conjunctive tissue, 4. mixed syndromes. Many observations will presented.
