[Vertical alveolar distraction osteogenesis of the posterior edentulous mandible: a case report]. / Distraction alvéolaire des secteurs postérieurs mandibulaires: à propos d'un cas clinique.

When it is necessary to increase the vertical height of the residual alveolar ridge, alveolar distraction osteogenesis has numerous advantages compared to other preprosthetic surgical procedures. It is frequently used for this purpose in the anterior region because of the obvious accessibility. The authors present a clinical case of edentulous posterior mandible, with insufficient vertical alveolar bone height, treated by alveolar distraction osteogenesis leading to three titanium fixtures. They explain their choice and discuss the preliminary results.

[Dentigerous cysts. Developmental aspects. Apropos of 3 cases]. / Les kystes dentigères. Aspect évolutif. A propos de trois observations.

Dentigerous cysts, also called follicularor corono-dental cysts, are malformative odontogenic cysts in the WHO classification of odontogenic tumors. We review the general characteristics of these frequent odontogenic tumors which always occur in associated with an included tooth. Diagnosis is based on clinical features, X-ray findings and pathology results. We report the evolutive aspect in three patients of different ages.

[Mandibular and malar tuberculosis. Apropos of a case]. / Tuberculose mandibulaire et malaire. A propos d'un cas.

A rare case of mandibular, malar and vertebral tuberculosis is reported. Special diagnostic and therapeutic features are discussed.

[Albers-Schönger disease disclosed by maxillary osteitis. Apropos of a case in an African]. / Maladie d'Albers-Schönberg révélée par une ostéite maxillaire. A propos d'une observation chez un africain.

The authors reported here a case of dominant form of osteopetrosis. The patient was a 28 years old man hospitalized for a mandibular osteitis consecutive to a tooth extraction. The clinical examination detected a splenomegaly. The laboratory tests showed anemia and thrombopenia. A radiographic skeletal survey detected a typical generalized osteocondensation. The authors pointed out the radiologic signs of the disease and underscored the difficulties in managing osteomyelitis of the jaw in such patients.

[Surgical treatment of acquired massive loss of substance of the roof of the mouth]. / Traitement chirurgical des grandes pertes de substance acquises du plafond buccal.

Surgical treatment of post-traumatic major loss of substance of the palate is reviewed, injuries in the series studied resulting from projectiles. The extensive loss of substance excludes the use of a mucous reservoir and skin grafts have to be employed. Free micro-anastomotic flaps represent a marked progress, as rapid results can be obtained, but these are not always totally effective. Pedicular flaps may have to be used, either of regional origin (cheek, neck, forehead, pectoral region) or from other zones (abdomen, internal surface of the arm). This allows effective, durable obturation of the palatine breach, and the application of the mobilized tissue to associated lesions that, because of the etiology, are almost always present.
