[Intubation using a submental approach]. / Intubation par voie sous-mentale.

Authors report a case of sub-mental approach for endotracheal intubation in maxillo-facial surgery. This unusual technique was simple to perform and remained uncomplicated.

[Dedifferentiated chondrosarcoma with maxillary involvement. An anatomo-clinical study, surgical treatment and prosthetic rehabilitation. Apropos of a case]. / Chondrosarcome dédifférencié à localisation maxillaire. Etude anatomo-clinique, traitement chirurgical et réhabilitation prothétique. A propos d'un cas.

A 19 year old girl presented with a dedifferentiated chondrosarcoma of maxilla. The recurring tumor, diagnosed initially from the provoked pain, appeared on the scan image as a heterogeneous mass containing numerous calcifications. Histology showed, within a well differentiated chondrosarcoma, an anaplastic sarcomatous zone of the malignant fibrous histiocytoma (MFH) type. This histologic appearance is consistent with a poorer clinical prognosis. Radical surgery of the 4th tumor recurrence was combined with maxillofacial prosthetic rehabilitation. This appears to be first reported case of a dedifferentiated chondrosarcoma of the MFH type located in the maxilla.

[Dentascan in dental implantation]. / Le dentascan en implantologie dentaire.

The software called dentascan utilizes the data acquired during a conventional CT examination to reconstruct accurate images with a 1/1 scale, both of sections taken at right angles to the axis of curvature of the bony relief of the maxillary or mandibular arch and of sections taken parallel to this axis. This means of investigation proves to be practical and useful for assessment before implantation.

[Dental implantology and expertise. Apropos of 6 cases]. / Implantologie dentaire et expertise. A propos de 6 cas.

Dental implants are used with increasing interest each day. This costly material, which is reimbursed neither by Public Social Protection Agencies nor by private health insurance companies, has become a cause for lawsuits. We analyzed the experts' conclusions regarding legal mementos and expert reports, wherein medical liability (4 cases) and repair of dental injury (2 cases) were put into question. The experts stress the need to regard this technique as surgical, and to have it necessarily yield results. Repair of damage caused by dental trauma using implants does not alter conventional approaches in terms of social security cover for maintenance and replacement of dental prosthesis. Difficulties encountered by experts in evaluating injuries sustained by bone-adapted implants are evoked.

[Temporomandibular joint dysfunction and neurofibromatosis. Apropos of a case]. / Dysfonctionnement des A.T.M. et neurofibromatose. A propos d'un cas.

The authors report one case of Von Recklinghausen's disease localized to the temporomandibular joint capsule and unilaterally associated with other cephalic manifestations. Although no other study, notably a CAT-scan, showed this tumor localization, surgical exploration was imperative and led to exeresis of the lesion which proved to be the treatment of choice.
