["Functional" genioplasty].

Genioplasty is a treatment method of the long face syndrome by reducing the lower face height to be equal, on lateral cephalometric radiography, to 55% of the total height of the anterior face whereas the height of the upper face is equal to 45% of this one (Wylie). Surgical technique described in this paper is particular by making up a tenon and mortise joint allowing a good stability of the lower fragment of osteotomy whose muscular insertions are preserved. Its effects are simultaneously functional and cosmetic because the oral musculature disorder is suppressed while chin aspect is modified.

[Seckel's syndrome (or bird's head dwarfism). Apropos of a case].

A 13-year-old boy presented with Seckel's syndrome, still called bird's head nanism, characterized by: --nanism, mental retardation, microcephaly, and protrusio of the middle third of the face. The typical facial appearance enabled a detailed study to be conducted of both clinical and radiological features, including, particularly, an architectural and structural analysis of profile teleradiographic images, providing objective data on the craniofacial deformities. Skeletal and systemic anomalies are also described, together with elements documented in the literature but absent in the present case. The etiology of this syndrome remains unknown.

[Otopalatodigital syndrome. Apropos of 3 female cases].

The oto-palato-digital syndrome about which much has been written on the male subject is analysed for a case of a mother and her two daughters which exhibited the main characteristics of the affliction with the exceptions of deafness and cleft-palate. These two manifestations, quoted in the name of the syndrome will be tackled later like its mode of transmission which still remains obscure.

[Functional anomalies of polymorphonuclears in Papillon-Lefèver disease (author's transl)].

Polymorphonuclear functions were studied in 3 patients of the same brotherhood with Papillon-Lefèvre disease (hyperkeratosis palmaris and plantaris and acute periodontosis resulting in loss of teeth) who developed severe and recurrent infections. Chemotaxis, oxygen consumption and production of H2 O2 were investigated by polarography, O2 production by quantitative reduction of nitroblue tetrazolium and iodination by the Pinus and Klebanoff technique. functional anomalies of polymorphonuclears involving chemotaxis, induced O2 consumption and H2 O2 production were detected in all three patients. This study confirms the presence of polymorphonuclear functional anomalies in patients with Papillon-Lefèvre disease. Analysis of the family tree of the patients, which went back to 1761, showed that this was probably not a chance association.

An architectural and structural craniofacial analysis: a new lateral cephalometric analysis.

The architectural and structural craniofacial analysis is based upon mutual balance of the cranial and facial bony structures. With this technique, the bases and calvaria of the cranium and then the face can be studied successively in relation to the cranium and craniospinal articulation. Statistical averages are avoided, and individual proportions influenced by the unique features of each skeleton are relied upon. The dentition is placed within the cephalic context, and therapy etiologic factors of dentofacial dysmorphoses which would not otherwise be demonstrated by conventional analysis are made obvious. This technique is particularly useful to the maxillofacial surgeon, as it clearly demonstrates all of the maxillofacial deformities and the pathologic balances that need to be corrected. In severe craniofacial malformations, it offers better possibilities than other cephalometric analysis methods of detecting the various cranial and facial anomalies which characterize these conditions.

Functional musculoskeletal correction of secondary unilateral cleft lip deformities: combined lip-nose correction and Le Fort I osteotomy.

Secondary cleft lip-palate deformities frequently involve a combination of skeletal, cartilagenous, dental and muscular deformities. Correction of these deformities should be based on normalization of function by restoring normal anatomy as much as possible. Functional correction of the lip musculature is best done at the same time as surgical correction of the skeletal-dental deformities. In this article, we outline a fundamental technique for secondary lip-nose correction based on muscle reorientation and a concomitant Le Fort I maxillary osteotomy.

[Synovial chondromatosis of the temporomandibular joint. A case report (author's transl)].

It is rare to see synovial chondromatosis lesions in the temporomandibular joint. They arise from metaplasic alterations in synovial tissue, to a degree sufficient to produce small rounded masses of cartilaginous tissue which become free intra-articular chondromas. A case of this type is described, this being apparently the first time that these lesions have been reported in the French published literature.

[Gas gangrene of dental origin. Report on four cases (author's transl)].

Four patients developed diffuse cervicofacial cellulitis following an acute circumscribed infection of dental origin. Necrosis of skin, subcutaneous and muscle layers was associated with a severe generalised toxic infective syndrome, producing a clinical picture and following a course identical with that observed in gas gangrene of the limbs. Anaerobic germs, normally present in the buccodental region, were at the origin of the affection in all four cases, chronic dental lesions providing favourable anaerobic conditions for an increase in their virulence. Three factors appear to be of importance for the development of gas gangrene from dental abscesses: insufficient or lack of suitable surgical treatment, the use of antibiotics not active against anaerobic germs, treatment with corticoids or anti-inflammatory drugs. Once gas gangrene has developed, possible intramediastinal spread should be investigated. Treatment is essentially surgical (with excision of necrotic tissue and wide drainage), plus penicillin therapy and hyperbaric oxygen. The prophylaxis of these gas gangrene lesions is discussed.

[Conservative surgical treatment for keratocysts of basal cell naevomatosis. Some results (author's transl)].

Excision of keratocysts of basal cell nevomatosis using the principle of conservative surgical treatment of maxillary cysts is usually followed by good secondary bone reconstruction without recurrence. Certain precautions are however necessary, the most important being the resection of the parts of the gums adherent to the cyst wall (where perhaps the cyst developed and where recurrences are most likely to occur). Any tooth germ which may be attached to the cyst must also be removed. Postoperative follow-up must include supervision of the bone reconstruction and tooth germ which have not yet developed (even in the absence of an image of a cyst) until the end of adolescence. In adult age, however, there is very little risk of new keratocysts cysts developing.
