The early detection and follow up of oral mucosa lesions are a must for every dentist. The importance of these activities is tremendous for oral cancerous and precancerous lesions, so every dentist is officially responsible for this important role in the public health. The modalities of such early detection and follow up are described.
The management of lesions of the oral mucosa requires precise knowledges and expertise in clinical care. This review article summarise the principles of the most validated therapeutical features about lesions of the oral mucosa. Global management procedures are described. Therapeutic modalities involving drugs, surgery, radiotherapy, chemotherapy, immunotherapy, electrotherapy, gene therapy and photodynamic therapy are detailed as well.
We describe a case of amyloidosis with oral involvement as a complication of multiple myeloma. Through a review of the literature, the classification, the pathogenesis, the epidemiological and clinical aspects, the prognosis, the diagnosis and medical treatment of amyloidosis are discussed.
The in 1994 published work in an issue of the Revue Belge de Médecine Dentaire devoted to oral cancer, aimed to describe and analyse the treatment modalities of oral cancer. Surgical treatment, radiotherapy and chemotherapy were systematically detailed. The esthetic and functional problems inherent to radical oncological surgery in the face and mouth were analysed. In most cases, surgical and/or prosthetic rehabilitative or reconstructive methods could limit these functional and esthetic inconvenient to acceptable sequelae. Dental prosthetic rehabilitation could with some limits benefit from dental osseointegrated implants: the problematic of dental implants in irradiated jaws has been claimed. The genuine indications of external radiotherapy and of brachytherapy were described and the risks so as the primordial prevention of jaw osteoradionecrosis were pointed out. Chemotherapy, either as palliative, adjuvant or as inductive treatment, had clearly shown important therapeutic limits. This presented work compares the actual treatment modalities of the oral cancer, pointing the main therapeutic acquisitions in the last 5 years and gives some optional indications for the future.
Salivary calculi are frequently formed in the submandibular duct. The most common sites are where the duct turns round the distal edge of the mylohyoid, where the duct crosses the lingual nerve, and just distal to the duct orifice. Untreated calculi can cause obstruction and glandular atrophy, and then may exfoliate through the floor of the mouth. An unusual case of cutaneous exfoliation of a salivary gland stone is presented. The importance of early diagnosis and treatment of sialolithiasis are discussed.
The authors report the first case of mandibular distraction osteogenesis applied to a fibula microvascularized flap used to reconstruct an almost entire mandible. The technique and complications are described. The literature is reviewed. The biological and physiological process of bone elongation by Ilizarov's method is explained according new studies on chondroid tissue. Preoperative planning of vectors of device placement and trajectory is essential for good results.
The management of oral injuries requires expertise in dental and medical cares. The need for a multidisciplinary assessment, including medical, has to be ascertained early. Diagnostic and management procedures are described as well as concomitant lesions such as maxillofacial bony fractures.
Gustatory rhinorrhea consists of free discharge of thin mucus from the nose during ingestion or after other gustatory stimulus. At maxillectomy, the nerve fibers going both to the salivary glands of the palate and to the secretory glands of the nasal mucosa may be damaged. A misdirection between the regenerating fibers of these two groups produces gustatory rhinorrhea.
While raising a standard radial forearm free flap, the ulnar artery was inadvertently cut. Therefore, the flap was raised, pedicled on the ulnar artery and vein. The case is discussed in the light of alternative solutions. Sommaire. Durant le prélèvement d'un lambeau radial libre classique, l'artère cubitale a été accidentellement sectionnée. Le lambeau a donc été prélevé, pédiculé sur les vaisseaux cubitaux. Les solutions alternatives possibles devant cette complication et les raisons de notre choix sont discutées.
This is the first report of a bilateral mandibular angle functional reconstruction with a single fibula free vascularized flap. This case provides a new application of the fibula flap in mandibular reconstruction. Its particular vascularization allows not only osteotomies but also ostectomy of a middle shaft.
We describe a case of osteosarcoma of the mandible presenting as a soft tissue mass associated with an enlargement of the mandibular canal at imaging work-up. Radiographic, isotopic, CT and MR features are reported.
Lithiasis of minor salivary glands is often considered to be extremely rare. However, recent publications reveal that minor salivary gland calculi are not so rare. Clinical features are not always typical, so clinical misdiagnosis is possible. Clinicians have to be aware to make a correct diagnosis. A case of sialolithiasis of minor salivary gland mimicking a mucous cyst is reported.
Acute or chronic sinusitis may be odontogenic. Bacteria involved in odontogenic sinusitis are specific organisms associated with the teeth (Streptococcus sanguis, Streptococcus salivarius, Streptococcus mutans, anaerobic germs). They are often secondary to an intrasinus foreign body following periodontitis. The treatment is both naso-sinusal and dental. Cysts of the maxilla can also invade the sinus. In particular, radiculo-dental cysts (periapical) must be surgically excised, in some cases associated with a middle meatotomy. Finally, one should look for oro-antral fistulae. The surgical technique for its closure should take into account the reversibility of the sinus lesions.
An 18-year-old male patient treated for Crohn's disease for 3 years developed buccal manifestations. The oro-facial symptoms disappeared completely with systemic corticosteroid treatment. Diagnosis, pathological features, treatment and pathogenesis hypotheses are discussed.

The authors report their experience of microsurgical reconstruction of the maxillofacial region with the radial forearm flap in 40 patients. After a brief historical and anatomical description, the cases are presented and specific considerations on the author's operative technique are detailed. The discussion on the advantages and the disadvantages of this flap ends the paper.
This retrospective study presents a clinical analysis of 41 patients with salivary gland calculi. Epidemiological, clinical, radiological, mineralogical and therapeutical aspects are presented and discussed. Surgical treatment is the most used but new technics of lithotripsy and/or ultrafine fibroscopy, which are more comfortable and less invasive, may reduce the surgical indications.
