[Chronic maxillofacial suppuration due to unknown plant foreign bodies. Apropos of 2 cases with CT scanning].

Common features in two patients with chronic suppurative lesions of the maxillofacial region from vegetable foreign bodies were : foreign body origin of the accident ; chronic nature of the suppuration (7 and 23 months respectively) ; multiple operations by different surgical teams ; radiotransparency of the foreign bodies. Positive signs on CT scanning can confirm the diagnosis, but cannot exclude it when normal images are obtained. The number and localization of wood fragments may limit the value of the scan, and fistulography and xeroradiography may then provide confirmation of the diagnosis.

[Malignant non-Hodgkin's lymphoma at a dental site. A case report].

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)].

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.
