[Diffuse sclerosing osteomyelitis of the mandible and SAPHO syndrome].

Background: Diffuse sclerosing osteomyelitis of the mandible (DSOM) and SAPHO (synovitis, acne, palmo-plantar pustulosis and psoriasis, hyperosteosis, osteitis) syndrome are not commonly associated. SAPHO has not been described to date in the stomatology and maxillo-facial surgery literature in French. Were report here a homogeneous series of 12 patients with DSOM.

Combined benign odontogenic tumors: CT and MR findings and histomorphologic evaluation.

Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma.

Myositis ossificans progressiva: five generations where the disease was exclusively limited to the maxillofacial region. A case report.

Myositis ossificans progressiva is an unusual autosomal-dominant inherited disease characterized by congenital malformations and osseous metaplasia of the fascia of the muscles and connective tissue leading to ossification of the relevant area. The case report is remarkable in that eight members of the same family over five generations manifested the exclusive localization of the disease in the maxillofacial region.

Infrahyoid myocutaneous flap in reconstructive maxillofacial cancer and trauma surgery.

We report the use of an island infrahyoid myocutaneous flap, pedicled on the superior thyroid vessels, in a group of 21 patients. This flap allows reconstruction of intraoral defects or defects of the lower portion of the face, as large as 10 x 4 cm. We used it in 15 cases to repair parts of the oral cavity, after tumour resection, in 2 patients with mandibular osteoradionecrosis and in 4 patients with gunshot injuries.

[Diffuse cervical cellulitis apropos of 15 cases].

A homogeneous series of 15 cases of diffuse cervical cellulitis originating in the oropharyngeal area were collected from December 1990 to April 1995. Despite early management, diffusion of the infectious processus was rapid with extension and development of severe mediastinal or pulmonary complications. When diffuse cervical cellulitis is suspected, early and adapted aggressive treatment must be initiated immediately: suppression of the causal factor, surgical exploration with repeated drainage depending on the clinical course assessed on CT scans, antibiotics effective against the aero-anaerobic flora.
