[An African disease: 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].

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.

Adult

[Extra-osseous mandibular ameloblastoma].

Gingival ameloblastoma is a rare odontogenic tumor which shares the same histology as endo-osseous ameloblastoma but from which it differs in terms of its course by the absence of "local malignancy". There would appear to be two probable origins concerning this lesion: Serre debris and the epithelium of the gingival mucosa. However, the etiopathogenesis remains controversial, raising problems of pathological distinction from gingival basal cell carcinoma.

[Maxillofacial localization of Burkitt's lymphoma. Apropos of 5 cases].

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.
