[Malignant fibrous histiocytoma of the maxillary sinus. Clinical and therapeutic aspects]. / Histiocytome fibreux malin du sinus maxillaire. Aspects cliniques et thérapeutiques.

Malignant fibrous histiocytomas, or MFH, have been individualized only since the last two decades. These sarcomas which usually develop from soft tissues are no longer considered rare, except in some of their facial sinus localizations. Two chapters will be particularly developed: the paramount significance of anatomopathological investigations owing to the difficulty in establishing the diagnosis, since MFHs may be mistaken for benign processes; the treatment which is, generally speaking, the same as for bone sarcomas.

[Clinical and therapeutic aspects of maxillofacial lesions of Paget's disease]. / Aspects cliniques et thérapeutiques des atteintes maxillo-faciales de la maladie de Paget.

Histopathology of mandibular swellings in two women aged 68 and 73 years respectively provided a diagnosis of Paget's disease. The complementary biological tests (phosphorus-calcium metabolism, alkaline phosphatase, hydroxyprolinuria) performed showed the increase in bone metabolism, while imaging techniques (conventional radiography, scintigraphy, CT scan) demonstrated numerous subclinical bony foci. Treatment of the facial deformity, if desirable esthetically or functionally necessary (alveolitis, osteitis) can only be surgical. If there is biological bone hypermetabolism, medical (diphosphonate, calcitonin) can be discussed with the rheumatologists. Evolutive risks are represented by rare sarcomatous transformations, osteomyelitis on Paget and monstrous deformities of the face, as in one of the patients reported who had refused all treatment over 37 years.

[Malignant non-Hodgkin's lymphoma at a dental site. A case report]. / Lymphome malin non hodgkinien à point de départ stomatologique. Un cas.

The authors report on a case of non-Hodgkin type malignant lymphoma in which signs of the disease develop initially in the upper maxilla. The authors were able to observe the patient over a period of 3 years. They used this opportunity, as follows: -to grade the tumour according to the different classification schemata proposed for these tumours, -to attempt to assess the changes and progress in drug therapy for these conditions, while at all times keeping an open mind regarding the value of results obtained in this manner.

[Treatment of mandibular fractures in children. Our therapeutic approach (author's transl)]. / Traitement des fractures mandibulaires chez l'enfant. Notre attitude thérapeutique.

This is a study of 15 fractures of the mandible in children. We were able to make the following conclusions: --the usual causes of these fractures are road traffic accidents or accidents at play, --the fracture is usually single (7 cases) multiple (8 cases) and in 13 children out of 15 there was a fracture of the condyle. --the presence of the first dentition and dental germs posed special problems. The treatment is mainly orthopedic, and the fracture is maintained in place by metallic arches which may or may not be completed with a resin dropper. Condyle fractures are treated classically by functional mechanotherapy. The indications of osteosynthesis seem to be limited to cases of very unstable fractures or where these are comminutive. The treatment of sequelae requires techniques very similar to orthodontic apparatuses.
