[Mesenchymatous chondrosarcoma of the superior maxillary bone. A case report]. / Chondrosarcome mésenchymateux de l'os maxillaire supérieur. A propos d'un cas.

The authors report a new case of mesenchymal chondrosarcoma (MCS), occurring in the upper jaw bone of a 19 year-old woman. Radiographic picture in the bone shows an aggressive osteolytic tumor suspect of malignancy. An incisional biopsy was practiced and the histologic examination has confirmed the diagnosis of MCS. Treatment have consisted of a large resection of maxilla with additional irradiation therapy. The postoperative course was marked by recurrence of the lesion one year later.

[An African disease: noma]. / A propos d'une maladie africaine: le noma.

Cancrum oris, formerly a fatal disease, is seen in poor regions of Africa. The starting point of the disease is acute ulceronecrotic gingivitis which results in an extensive gangrenous plaque destroying, from inside working outwards, the dental arch, the maxilla and all of the soft tissues of the face. At the stage of sequelae, the therapeutic problem is twofold: functional and morphological. It is based on a panoply of technical procedures of surgical reconstruction.

[Maxillo-mandibular osteotomy]. / Les ostéotomies maxillo-mandibulaires.

The authors present their experience of maxillo-mandibular osteotomies performed at the Charles Nicolle Hospital in Tunis. The objective of this paper is to describe the preliminary steps (clinical, radiographic, photographic, modelling, cephalometric) in order to obtain a precise diagnosis of the dysmorphosis. They use Burstone's cephalometric analyses which allow evaluation of the relations between soft tissues which do not correspond to the relations of bony and dental displacement. They also present several clinical cases, the pre-operative steps and, most importantly, Burstone's cephalometric analyses demonstrating that, after osteotomies, the cephalometric values for soft tissues approach normal values. Complete analysis of the naso-maxillary profile may correct the motivation for consultation in some cases. The indication for Lefort I osteotomy is sometimes more appropriate than rhinoplasty. Preoperative orthodontic preparation is often required. Functional rehabilitation is necessary to adapt the orofacial muscles to the new shapes of the dental arch and to prevent recurrence.

[Maxillofacial localization of Burkitt's lymphoma. Apropos of 5 cases]. / Localisations maxillo-faciales du lymphome de Burkitt. A propos de 5 cas.

Five children presented with a Burkitt's lymphoma localized to the maxillofacial region. The disease and its clinical manifestations are reviewed briefly, and the frequency of this tumor in Tunisia is emphasized. The Tunisian Burkitt tumor appears to be an intermediate entity between the "non-endemic" form and the African form.

[A new ligation method in treating maxillary fractures in children]. / Un procédé nouveau de ligature dans le traitement des fractures des maxillaires chez l'enfant.

A new method for orthopedic treatment, based on the ligature procedure described by Popov E. in Bulgaria, has been adapted for therapy of mandibular fractures in children.
